I'm having trouble with my phone's display
You may be experiencing any of these issues:
  • Content on the display is distorted
  • Display does not rotate with the phone
  • Display rotates unintentionally
  • Display turns off during use
  • Display is too bright, dark, or brightness changes
  • Screen is dark after completing a call

The root causes of display issues can vary and it is important to verify if the issue is related to the settings, content or app being used, or the phone hardware. Issues with the display brightness or screen rotating are usually resolved by verifying and adjusting the display options of the phone. If the issue only occurs with content being streamed or viewed online, it is recommended to use locally stored content for troubleshooting purposes.

Power cycling your phone may help to solve the issue. Follow these steps:
  1. Press and hold the POWER button until the Phone Options appear.
  2. Tap Power Off and wait for the phone to fully turn off.
  3. Wait for a few moments, and then turn the phone on by pressing and holding the POWER button.

Check to see if the issue with the display persists when viewing multiple pictures, videos, or in multiple applications.

If your phone does not rotate or rotates unintentionally, verify and adjust the auto-rotate settings of your phone.
  1. Go to Settings > Display & gestures.
  2. Check or uncheck the Auto-Rotate option.
If the display is too bright or dark, or the display brightness changes unintentionally, verify and adjust the phone's brightness settings.
  1. Go to Settings > Display & gestures.
  2. Tap Brightness Level.
  3. Adjust the settings using the Brightness Level slider bar.
  4. Check or uncheck the Automatic Brightness option.
    Note: When the Automatic Brightness option is enabled, the phone will grow darker or brighter depending on the surroundings. The Brightness Level slider controls the base brightness of the phone's screen.
While on a call, the proximity sensor will darken the screen of the phone when it detects it is near the users face to prevent accidental input while on a call. If the screen remains dark after completing a phone call, verify the proximity sensor of the phone is functioning properly.
  1. Open the Phone app.
  2. Dial *#*#DIAG#*#* (*#*#3424#*#*) to launch the tool.
  3. Check the box for P-Sensor Test and then touch Run.
  4. Follow the onscreen instructions.
