Understanding White Lines on Your iPhone Screen
White lines, whether horizontal, vertical, or in a grid pattern, on an iPhone screen are a common indicator of a hardware or software malfunction. These lines can disrupt your viewing experience, making it difficult to read text, view images, or use apps. Before attempting any fixes, it's crucial to understand that while some issues can be resolved by the user, persistent or severe lines often point to a more significant internal problem requiring professional attention. This guide will walk you through the diagnostic and corrective measures you can take.
These visual anomalies can manifest in several ways: thin, solid lines; flickering lines; or even blocky, pixelated white areas. The appearance and location of these lines can offer clues about the underlying cause. For instance, a single, persistent vertical line might suggest a problem with a specific column of pixels or the display's internal circuitry, whereas a broader pattern of white noise or lines could indicate a more general display controller issue or damage to the screen assembly itself. Identifying the pattern helps in narrowing down potential solutions.

Common Causes of White Lines
The appearance of white lines on your iPhone's display isn't typically caused by a single factor. Instead, it often results from a combination of potential issues that affect the screen's integrity or its connection to the device's logic board. Understanding these causes is the first step toward effective resolution. Many of these issues are related to the physical components of the iPhone, particularly the delicate display assembly and its internal connections.
One of the most frequent culprits is physical damage, even if it's not immediately obvious. A drop, impact, or excessive pressure on the iPhone can dislodge the display cable, loosen its connection to the logic board, or even cause micro-fractures within the screen layers. Even if the screen glass appears intact, internal damage can still occur. Water damage is another significant cause; moisture ingress can corrode internal connections and components, leading to display irregularities like white lines or a completely black iPhone screen.
Software glitches, while less common for persistent white lines, can sometimes cause temporary display artifacts. A corrupted operating system file or a bug introduced by a recent app installation or update might briefly affect how the display renders graphics. However, software issues typically result in more transient problems like screen flickering or temporary freezing, rather than distinct white lines that remain visible.
Internal hardware failures within the display panel itself or the graphics processing unit (GPU) can also lead to such visual defects. Over time, or due to manufacturing defects, pixels can fail, or the controller responsible for managing the display signal might malfunction. These failures are often permanent and necessitate a hardware replacement.
The primary drivers behind white lines are typically physical stress, water exposure, or internal component failure.
Prerequisites and Initial Checks
Before diving into more complex troubleshooting, performing a few basic checks can help determine if the white lines are a transient software issue or a more permanent hardware problem. These steps are non-invasive and require no specialized tools, making them the logical starting point for any user experiencing this display anomaly. Ensuring your iPhone is in a state where these tests can be performed accurately is paramount.
First, ensure your iPhone's software is up to date. While white lines are predominantly hardware-related, an outdated or buggy iOS version could, in rare instances, contribute to display anomalies. Navigate to Settings > General > Software Update and install any available updates. If an update is in progress, allow it to complete fully. Sometimes, the update process itself can resolve minor software conflicts that might be impacting the display.
Next, observe the lines carefully. Do they appear immediately after turning the phone on, or do they emerge after a specific action? Do they change or disappear when you apply slight pressure to the screen or casing? Are they present on the iPhone home screen, within apps, or only on specific content? Note any patterns or conditions under which the lines appear or disappear, as this information is invaluable for diagnosis and for communicating with support if needed.
It is also prudent to test the display with different content. Switch between dark and light modes, open various applications, and view photos or videos. If the white lines are consistently present across all interfaces and content, it strongly suggests a hardware issue with the display or its connection. Conversely, if the lines only appear in a specific app or under certain conditions, it might indicate a software conflict or a rendering issue within that particular application, potentially similar to an iPhone pause screen effect.
Always check for software updates before assuming a hardware failure.
Checking for Software-Related Glitches
While white lines are often hardware-driven, it is wise to rule out any software-related anomalies. A simple restart can clear temporary glitches that might be affecting the display's rendering. For most iPhone models, this involves pressing and holding the side button (or top button) and either volume button until the power off slider appears, then dragging the slider. For models without a Home button, press and hold the side button and either volume button until the power off slider appears, then drag the slider. For iPhone 8 or earlier, press and hold the side (or top) button until the slider appears, then drag the slider. After the device powers off, press and hold the side (or top) button again until you see the Apple logo to turn it back on.
A more forceful method to address potential software conflicts is a force restart. This process is different depending on your iPhone model. For iPhone 8 or later (including iPhone SE 2nd and 3rd generation), quickly press and release the Volume Up button, quickly press and release the Volume Down button, then press and hold the Side button until you see the Apple logo. For iPhone 7 or iPhone 7 Plus, press and hold both the Side and Volume Down buttons for at least 10 seconds, until you see the Apple logo. For iPhone 6s or earlier (including iPhone SE 1st generation), press and hold both the Home and Side (or Top) buttons for at least 10 seconds, until you see the Apple logo. A force restart can resolve deeper software issues that a standard restart might miss, but it does not erase your data.
If the white lines persist after a force restart, consider if they appeared after installing a new app or updating iOS. If so, and if you suspect the software is the cause, you might consider uninstalling recently added apps or, as a last resort for software, performing a factory reset. A factory reset erases all data on your iPhone, so it's crucial to back up your device first via iCloud or a computer. You can find this option under Settings > General > Transfer or Reset iPhone > Erase All Content and Settings. This action reverts the iPhone to its original software state, effectively ruling out any lingering software corruption.

Troubleshooting Software-Related Causes
When white lines appear on an iPhone screen, the first instinct is often to consider hardware failure. However, understanding the potential software-related causes and their resolutions is a crucial step in the diagnostic process. While less common than physical damage, software anomalies can sometimes mimic hardware issues, offering a more accessible fix.
The iOS operating system manages all visual output, including how the display renders images and text. If critical system processes become corrupted, or if a bug exists within the OS or a specific application, it can lead to graphical errors. These errors might manifest as flickering, unusual colors, or, in some cases, lines across the screen. This is similar to how a corrupted file might prevent a document from opening correctly; a corrupted display driver or rendering process can cause visual artifacts.
Consider the timing. Did the white lines appear immediately after a software update? Or following the installation of a new app? If so, the software itself could be the culprit. A recent iOS update might contain a bug that affects certain display controllers, or a newly installed app could be conflicting with the system's graphics rendering. In such scenarios, the fix often involves waiting for Apple to release a patch or finding an alternative to the problematic app.
The appearance of white lines might also be a symptom of a broader display driver issue. These drivers are software components that allow the operating system to communicate with the display hardware. If these drivers become unstable or corrupted, visual distortions can occur. A force restart, as detailed previously, is often effective in resetting these drivers and resolving temporary glitches. If the issue is persistent and tied to a specific iOS version, backing up your iPhone and performing a clean install of the latest compatible iOS version (or even rolling back if possible, though this is complex and often unsupported) can be a way to address deep-seated software corruption.
A force restart is a vital first step in resolving transient software-induced display anomalies.
Resetting iPhone Settings
If a simple restart or force restart doesn't resolve the white lines, the next software-related step is to reset your iPhone's settings. This action is less drastic than a full factory reset because it only affects your Wi-Fi passwords, Bluetooth pairings, VPN configurations, location settings, and privacy settings. It does not delete your apps, data, photos, or media. This is particularly useful if the issue is related to network settings or other configurations that might indirectly impact system performance or display behavior.
To reset your settings, go to Settings > General > Transfer or Reset iPhone. Tap on 'Reset', and then select 'Reset All Settings'. You will be prompted to enter your passcode. Confirm that you wish to reset all settings. After the iPhone reboots, check if the white lines have disappeared. This process can clear out any corrupted preference files or conflicting configuration settings that might be contributing to the display problem without the risk of data loss.
If the white lines are still present after resetting all settings, it further reinforces the likelihood of a hardware issue. This step effectively eliminates software configuration as a primary cause, leaving hardware as the most probable reason. It's important to understand that even if you reset all settings, persistent white lines that appear immediately upon startup or remain static across all screens are almost certainly hardware-related.
Resetting all settings is a non-destructive way to clear corrupted configuration files.
Troubleshooting Hardware-Related Causes
When software troubleshooting steps fail to resolve the white lines on your iPhone screen, the focus must shift to potential hardware issues. These are often more complex and may require professional intervention, but understanding them can help you make informed decisions about repair or replacement. Hardware problems can range from minor connection issues to significant component damage.
The most common hardware cause is a loose or damaged display connector. The iPhone's screen connects to the logic board via several delicate ribbon cables. If the iPhone has been dropped, subjected to impact, or exposed to moisture, these cables can become dislodged or frayed. This disruption in the signal path from the logic board to the display panel can result in visual artifacts like white lines, dead pixels, or screen discoloration. Sometimes, a simple reseating of these cables by a qualified technician can resolve the problem.
Physical damage to the display panel itself is another frequent cause. This can include micro-fractures in the LCD or OLED layer, damage to the digitizer, or issues with the backlight. Even if the glass is not cracked, the underlying display technology can be compromised. This type of damage is often irreparable and requires the entire screen assembly to be replaced. The nature of the lines—whether they are sharp and defined or fuzzy and diffuse—can sometimes provide clues about the extent of the damage.
Water damage, as mentioned, is a serious threat to internal components. Moisture can lead to corrosion of the display connectors, logic board traces, or even the display panel itself, causing a cascade of failures that can manifest as persistent white lines or a completely unresponsive screen. iPhones are designed to be water-resistant, not waterproof, and exposure beyond their rated limits, especially to saltwater or chlorinated water, can be particularly damaging.
A damaged display connector is a frequent cause of persistent white lines on iPhone screens.
Assessing Physical Damage and Connection Issues
Carefully inspect your iPhone for any signs of physical damage. Look for dents, bends, or cracks around the edges of the device or on the screen itself. While a cracked screen might lead to lines, sometimes subtle damage that isn't immediately apparent can be the source. Pay attention to the condition of the charging port and headphone jack (if applicable) for any debris or signs of corrosion that might indicate past water exposure.
If you are comfortable doing so, and if your device is out of warranty or you accept the risk, you could consider opening the iPhone to check the display cable connection. However, this is an advanced procedure and is not recommended for most users. Attempting to open an iPhone without the correct tools and knowledge can cause further damage, void your warranty, and expose you to potentially hazardous components. If you choose this route, ensure you follow a reputable teardown guide specifically for your iPhone model and take static precautions.
The display cable connects to a port on the logic board. If the cable appears securely seated, the issue might lie with the cable itself or the display panel. If it's loose, carefully reseating it might fix the problem. However, if the cable is visibly damaged (torn, frayed, corroded), it will need replacement. This step requires precision, as these cables are extremely fragile.
Inspect your iPhone for any visible signs of impact or water exposure.
When to Seek Professional Repair
If none of the software troubleshooting steps resolve the white lines, and you are unwilling or unable to perform internal hardware checks, it is time to seek professional assistance. For iPhones still under warranty or covered by AppleCare+, contacting Apple Support is the most advisable course of action. They can diagnose the issue and arrange for repair or replacement if the damage is covered.
If your iPhone is out of warranty, you have several options. You can opt for an Apple Authorized Service Provider, which uses genuine Apple parts and follows Apple's repair standards. Alternatively, you can seek out a reputable third-party repair shop. While often more affordable, ensure they have a good track record, experienced technicians, and offer a warranty on their work. Be aware that using non-genuine parts or unauthorized repair services could potentially lead to further issues or affect future repairs by Apple.
When you seek professional help, be prepared to describe the issue in detail: when the lines appeared, their pattern, and any troubleshooting steps you’ve already taken. This information will help the technician diagnose the problem more efficiently. The repair process typically involves diagnosing the specific component failure and replacing the damaged part, which is usually the display assembly for issues like white lines. The cost will vary based on the iPhone model and the extent of the damage.
Professional diagnosis is essential for persistent hardware-related display issues.
Advanced Troubleshooting: Display Calibration and Settings
While most white line issues on an iPhone screen stem from hardware problems, there are a few advanced software settings and calibration checks that can, in rare instances, influence display behavior or at least rule out specific software conflicts. These steps are more involved than basic restarts and require a deeper understanding of your iPhone's accessibility and display features.
One area to explore is the accessibility settings related to display. For example, 'Reduce Motion' (Settings > Accessibility > Motion) can sometimes alter how animations are displayed, though it's unlikely to cause persistent white lines. More relevant might be 'Color Filters' (Settings > Accessibility > Display & Text Size > Color Filters) or 'Increase Contrast' (under Display & Text Size). If these settings were accidentally enabled or adjusted, they could potentially alter the visual output in unexpected ways, though typically not by introducing solid white lines. It is worth ensuring these are set to their default or 'off' state to rule them out.
Another consideration is the 'Display Zoom' feature (Settings > Display & Brightness > Display Zoom). While this scales the interface, it doesn't directly affect the pixel rendering in a way that would create lines. However, complex interactions between display settings and iOS can sometimes lead to unforeseen visual artifacts. Reverting to default display settings, if possible, is a good practice.
For OLED screens, 'True Tone' and 'Night Shift' are features that dynamically adjust color temperature. While these are designed to improve viewing comfort and do not directly cause white lines, disabling them temporarily can sometimes help in diagnosing display anomalies. You can find these under Settings > Display & Brightness. The logic here is that any dynamic color or brightness adjustment that is malfunctioning could theoretically contribute to erratic display behavior.
Always check accessibility and display settings for unintended configurations.
Checking Display Brightness and Auto-Brightness
The iPhone's display brightness setting and the Auto-Brightness feature can influence perceived display quality, though they rarely cause hard white lines. However, in conjunction with other software issues or specific hardware sensitivities, extreme brightness levels or faulty auto-brightness adjustments might exacerbate existing display problems. It is advisable to check and adjust these settings as part of a comprehensive troubleshooting process.
You can manually adjust the brightness by swiping down from the top-right corner of the screen (on newer iPhones) or swiping up from the bottom (on older iPhones) to access the Control Center. Drag the brightness slider up or down. You can also find manual brightness controls under Settings > Display & Brightness. Set the brightness to a mid-level to see if the white lines change or disappear. If they are still present, try setting the brightness to its maximum and minimum levels.
The Auto-Brightness feature (Settings > Accessibility > Display & Text Size) automatically adjusts screen brightness based on ambient light. While generally beneficial, a malfunctioning ambient light sensor or a software bug could cause erratic brightness changes. To test this, you can temporarily disable Auto-Brightness and manually set a consistent brightness level. If the white lines appear or disappear based on ambient light conditions even with Auto-Brightness off, it might indicate a more complex issue with the display driver or hardware.
It's important to note that these brightness adjustments are unlikely to fix actual white lines caused by physical damage or connection issues. Their primary purpose here is to ensure that no software-related display behavior is contributing to or mimicking the problem. If the lines are still visible and consistent regardless of brightness settings or Auto-Brightness status, you can confidently move on to considering hardware repair.
Manually adjust brightness to its extremes to rule out brightness-related issues.
Specific iPhone Models and Line Issues
While the general troubleshooting steps for white lines on an iPhone screen apply across most models, certain iPhone generations or specific hardware characteristics might exhibit unique behaviors or be more prone to particular types of display issues. Understanding how your specific iPhone model might be affected can refine the troubleshooting process and manage expectations regarding repair.
For example, older iPhone models with LCD screens (like the iPhone 6, 7, or 8 series) might experience lines due to damage to the LCD panel itself or the backlighting system. The way these lines appear on an LCD can differ from OLED displays. LCD panels use a backlight and liquid crystals to create images, and damage to either can lead to a loss of pixel control, resulting in uniform white or discolored lines.
Newer iPhones, particularly those with OLED displays (iPhone X, XS, XR, 11 Pro, 12 series, 13 series, 14 series, 15 series), might encounter issues related to the pixel technology. OLED pixels emit their own light, and while this offers superior contrast and deep blacks, specific pixel failures or issues with the display controller board can still result in white lines or other artifacts. Sometimes, a specific type of defect known as 'burn-in' or 'image retention' can appear as a faint ghost image, but actual white lines are more indicative of a failure rather than degradation.
The physical design of each iPhone model also plays a role. The way the display assembly is integrated and the placement of internal connectors can affect susceptibility to damage from drops or impacts. For instance, models with flatter edges might be more prone to screen damage from side impacts compared to those with more rounded designs. The thickness of the bezels and the overall rigidity of the chassis also contribute to how well the display can withstand external forces.
Different iPhone generations use distinct display technologies that can affect line appearance.
Common Issues with OLED vs. LCD Screens
The fundamental difference between OLED and LCD screens is how they produce light. LCD (Liquid Crystal Display) screens use a backlight that is always on, with liquid crystals and color filters controlling which light passes through to create an image. OLED (Organic Light-Emitting Diode) screens, on the other hand, have individual pixels that emit their own light, allowing for perfect blacks when a pixel is turned off. This difference has implications for how display faults appear.
On an LCD screen, white lines often appear as a result of damage to the backlight or the diffusion layer beneath the liquid crystals. They can be uniform and span the entire width or height of the screen. A common cause is pressure or impact that deforms the LCD panel or damages the internal circuitry responsible for controlling segments of pixels. If the connection cable for a segment of pixels is damaged or loose, it could result in a persistent line of white or dead pixels.
OLED screens are more susceptible to individual pixel failures. If a specific set of pixels along a vertical or horizontal path fails to receive power or signal correctly, they might default to a 'white' state or become completely black. This can manifest as a thin white line, similar to an LCD issue. However, OLEDs can also suffer from 'burn-in' where static images leave a permanent imprint; this usually appears as a ghosted image, not a solid white line, but it's a related display defect. Issues with the OLED controller board can also cause more widespread line artifacts.
When troubleshooting white lines, consider your iPhone's screen type. If you have an OLED model and the lines are very thin and sharp, it could be a pixel defect. If they are broader or appear to be related to the overall illumination, an LCD backlight issue might be suspected. Regardless of the type, if the lines are persistent and disruptive, a screen replacement is often the only viable solution.
OLED screens can display lines due to individual pixel failure or controller board issues.
When to Replace Your iPhone Screen
Deciding when to replace your iPhone screen is a critical step in resolving persistent white lines. If you've exhausted all software troubleshooting methods and are facing a clear hardware issue, replacement becomes the most practical solution. This decision is usually based on the severity of the lines and their impact on usability.
If the white lines obscure a significant portion of the screen, making it impossible to read text, view content, or interact with buttons, then replacement is almost certainly necessary. For example, if a grid of white lines covers half the display, or a thick white bar runs vertically down the center, the iPhone's functionality is severely compromised. In such cases, continuing to use the device without repair might even lead to further damage if the screen's integrity is compromised.
Even if the lines are thin and seem minor, their persistence is a strong indicator of an underlying hardware problem. A single, thin white line that appears immediately upon startup and doesn't disappear with any software reset is a sign of a faulty pixel column or a connection issue that won't resolve on its own. Attempting to ignore such issues can sometimes lead to them worsening over time, potentially affecting adjacent pixels or display areas.
Consider the overall condition of your iPhone. If the device is very old, nearing the end of its software update support, or has other significant issues, the cost of screen replacement might not be justified. In such scenarios, it might be more economical to upgrade to a newer model. However, for relatively recent iPhones, a screen replacement can often extend the device's useful life by several years.
Replace the screen when lines significantly impair usability or are persistent.
Understanding Replacement Costs and Options
The cost of replacing an iPhone screen varies considerably depending on the iPhone model, the type of screen (LCD vs. OLED), and where you get the repair done. Apple typically charges a premium for screen replacements, using genuine Apple parts and ensuring the repair meets their standards. For newer models with OLED displays, screen replacements can be among the more expensive repairs.
For example, an iPhone 14 Pro Max screen replacement would cost more than an iPhone 11. You can check Apple's official repair cost estimator on their website to get an idea of the pricing for your specific model. If your iPhone is covered by AppleCare+, the cost will be significantly lower, usually a flat service fee, provided the damage is not classified as accidental damage beyond normal wear and tear (though screen issues are often covered). If your iPhone is out of warranty, the price will be the full out-of-pocket cost.
Third-party repair shops often offer lower prices for screen replacements. However, it's crucial to vet these providers carefully. Look for shops that specialize in iPhone repairs, have positive reviews, and offer a warranty on their parts and labor. Some independent repair shops may use non-genuine parts, which can sometimes affect display quality, touch sensitivity, or even future software updates. It is always best to inquire about the origin of the replacement parts and the warranty provided.
Before proceeding with a replacement, weigh the cost against the value of your current iPhone and the cost of a new device. For older models, sometimes the cost of a screen replacement can approach the price of a refurbished or budget-friendly new phone. Make an informed decision based on your budget, the age of your device, and your needs.
Compare repair costs with the device's value before deciding on replacement.
Preventative Measures for Display Health
While white lines on an iPhone screen often appear unexpectedly, certain preventative measures can significantly reduce the risk of future display damage and maintain your device's visual integrity. Adopting good habits can protect your iPhone from common causes of screen issues, including impacts, pressure, and moisture.
Using a high-quality protective case is one of the most effective ways to prevent physical damage. A robust case with reinforced corners and a raised lip around the screen can absorb the shock of drops and prevent the display from making direct contact with hard surfaces. Many cases also have a lip that extends slightly above the screen, offering protection even when the phone is placed face down.
A screen protector, especially one made from tempered glass, adds another layer of defense. It's designed to absorb the impact of drops and scratches, protecting the iPhone's actual display underneath. If the screen protector cracks or shatters, it can often be replaced for a relatively low cost, saving the more expensive iPhone display from damage. Some screen protectors also offer additional features like privacy filtering, reducing the viewing angle to prevent others from seeing your phone screen.
Avoid placing your iPhone in situations where it could be subjected to excessive pressure. For instance, avoid putting it in a back pocket where it could be sat on, or in a bag with heavy objects. Extreme temperatures, both hot and cold, can also affect battery performance and potentially the display. Never leave your iPhone in direct sunlight on a hot day or in a very cold environment for extended periods.
Invest in a quality case and screen protector to guard against physical damage.
Protecting Your iPhone from Water Damage
Water damage remains one of the most destructive forces for electronic devices, including iPhones. While modern iPhones have improved water resistance, they are not waterproof, and exposure to liquids can still cause significant harm, leading to issues like white lines, corrosion, or complete device failure. Taking precautions against liquid exposure is paramount for maintaining your iPhone's display health.
Avoid using your iPhone near water sources, such as swimming pools, hot tubs, sinks, or during heavy rain. If you frequently use your phone for navigation or media outdoors, consider a waterproof pouch or case, especially if you are in an environment where spills are likely. Be particularly cautious in bathrooms, kitchens, and at the beach.
If your iPhone does come into contact with liquid, act swiftly. Do not attempt to turn it on or charge it. Immediately disconnect any accessories. If possible, dry the exterior thoroughly with a soft, lint-free cloth. Do not use heat sources like hair dryers, as this can push liquid further into the device or cause heat damage. If it's a liquid other than fresh water (e.g., salt water, soda, coffee), rinse the exterior carefully with plain, distilled water if you can do so without further ingress, then dry it thoroughly. Place the iPhone in a well-ventilated area, ideally with the charging port facing down, to allow any residual moisture to escape. While the old rice trick is popular, it's not very effective and can introduce dust or debris into ports; silica gel packets are a better desiccant if available.
Contact Apple Support or an authorized service provider as soon as possible to have the device inspected. Liquid damage is often not covered under standard warranties, but professional assessment can determine the extent of the damage and the best course of action for repair or data recovery.
Always dry your iPhone immediately if it gets wet and avoid charging it.
When to Contact Apple Support
Knowing when to engage with Apple Support is crucial for navigating repairs and ensuring your iPhone is handled by qualified technicians. If your troubleshooting efforts have failed to resolve the white lines, or if you suspect a manufacturing defect or warranty-eligible issue, reaching out to Apple is the logical next step.
You should contact Apple Support if your iPhone is still under its one-year limited warranty or covered by AppleCare+. These programs offer peace of mind and often include repair or replacement services at a reduced cost or no cost, depending on the nature of the problem. Even if you suspect accidental damage, it's worth contacting them to understand your options, as they can provide accurate quotes for out-of-warranty repairs.
If the white lines appeared shortly after purchasing the iPhone, it might indicate a manufacturing defect. In such cases, Apple is generally more accommodating with repairs or replacements, even if the device is technically out of the strict warranty period. Documenting when the issue first occurred and any steps you took can be helpful when speaking with support.
You can initiate contact with Apple Support through various channels: their official website, the Apple Support app on another Apple device, or by calling them directly. They can guide you through remote diagnostics, schedule an in-person appointment at an Apple Store or Apple Authorized Service Provider, or arrange for mail-in service.
Contact Apple Support for warranty claims or professional diagnosis.
Preparing for a Support Interaction
To make your interaction with Apple Support as efficient as possible, preparation is key. Before you contact them, gather all relevant information about your iPhone and the issue. This includes your iPhone's serial number or IMEI, the specific model, the iOS version it is running, and a detailed description of the white lines.
Be ready to explain the troubleshooting steps you have already taken. This includes whether you performed software updates, restarts, force restarts, or reset settings. Mention when the white lines first appeared and under what circumstances. If you have AppleCare+ coverage, have your proof of purchase or coverage details handy.
If you are scheduling an in-person appointment, ensure you back up your iPhone data beforehand. Apple may need to erase your device as part of the repair process. Following the appointment, Apple technicians will assess the device, provide a diagnosis, and present you with repair options and associated costs. If the issue is covered under warranty or AppleCare+, the repair might be free. If not, you will receive a quote for the service, allowing you to decide whether to proceed with the repair.
Always back up your iPhone before any service appointment.
