Display turned white after updating ios 16.2

Hello ahamed145,

It sounds like you may be experiencing an issue with your iPhone after updating to iOS 16.2. There are a few potential causes for a white display on an iPhone, and several steps you can try to troubleshoot the issue.

1. Restart your iPhone: Sometimes, a simple restart can resolve a variety of issues with an iPhone. To restart your iPhone, press and hold the power button (also known as the sleep/wake button) until the "Slide to Power Off" slider appears. Drag the slider to power off your device, and then press and hold the power button again to turn it back on.
2. Check for a hardware issue: If the display is completely white and nothing appears on the screen, it is possible that there may be a hardware issue with your iPhone. You can try connecting your iPhone to a computer and see if it is recognized. If it is not recognized, it could indicate a hardware issue that may need to be addressed by a professional.
3. Check for an app issue: If the display is white but you see an app icon or logo on the screen, it is possible that an app is causing the issue. You can try force-closing the app by double-tapping the home button and swiping up on the app preview to close it. If the issue persists, you can try uninstalling the app and reinstalling it from the App Store.
4. Restore your iPhone: If none of the above steps have resolved the issue, you may need to restore your iPhone. Before restoring, make sure to back up your device to iCloud or iTunes. Then, follow these steps:

• Connect your iPhone to a computer using a Lightning-to-USB cable.
• Open iTunes on your computer.
• If prompted, click "Trust This Computer" on your iPhone.
• Click the iPhone icon in iTunes.
• Click the "Summary" tab.
• Click the "Restore iPhone" button.
• Click "Restore" to confirm.

I hope these steps help resolve the issue with your iPhone. If you continue to experience problems after trying these steps, it may be best to contact Apple Support for further assistance.
