How do I fix a permanent white screen on my device ?

Possible Causes of the White Screen​

1. Third-Party Apps

  • Cause: The use of third-party apps can sometimes lead to the device showing a white screen after one of the apps crashes.
  • Solution: Try restarting the device. If you suspect a specific app is causing the issue, consider uninstalling it to see if the problem persists.

2. Volume Up Button Stuck or Held

  • Cause: If the volume-up button is stuck or accidentally held down while turning on the device, it may trigger the device to enter “download mode,” which can display a white screen.
  • Solution: Ensure that the volume-up button is not held down when turning on the device. If it was stuck, try gently releasing it and restarting the device.

3. Disconnection with PayApp

  • Cause: Sometimes, if the device gets disconnected from PayApp, it can encounter issues with deinstalling PayApp, leading to a white screen.
  • Solution: Perform a double reboot. First, power off the device completely, wait for a few seconds, and then turn it back on. If the issue persists, try rebooting again.
