4. Screen Burn-in

Screen burn-in occurs when an image or pattern on the screen remains visible even after it has been replaced by another image. This issue is more commonly seen on older iPhones with LCD screens. To troubleshoot screen burn-in, follow these steps:
a.Use a screen burn-in prevention app: There are several apps available on the App Store that can help prevent and reduce screen burn-in. These apps display colorful patterns or animations to even out pixel usage on the screen.
b. Adjust screen timeout settings: Screens that remain on for extended periods are more susceptible to burn-in. To mitigate this, go to Settings > Display & Brightness > Auto-Lock and set it to a shorter time period.
c. Avoid static images: Try to avoid displaying static images, such as wallpapers or icons, for prolonged periods. Changing your wallpaper regularly or using dynamic wallpapers can help prevent burn-in.
d. Enable dark mode: Using dark mode or inverted colors can reduce the strain on the pixels and potentially prevent screen burn-in.

5. Display Color Inaccuracy

If you notice that the colors on your iPhone's LCD screen appear washed out or inaccurate, there are a few things you can do to address this issue:
a. Adjust color temperature: Go to Settings > Display & Brightness > True Tone to enable this feature, which automatically adjusts the screen's color temperature based on the ambient lighting conditions.
b. Calibrate the display: If you want more control over color accuracy, you can manually calibrate the display by using a calibration tool or app. These tools guide you through the process of adjusting color balance, contrast, and brightness.
c.Disable Night Shift: Night Shift can tint the screen towards the warmer end of the color spectrum, which may affect color accuracy. To disable Night Shift, go to Settings > Display & Brightness > Night Shift.
d. Reset display settings: If none of the above steps work, try resetting all display settings to their default values. Go to Settings > Display & Brightness > Reset > Reset Display Settings.
