Clear App Cache / Data:

NOTE: In case one of your apps freezes, crashes, takes up too much storage inexplicably or otherwise doesn’t work as intended, you can try fixing the issues by clearing the app cache / data.

  2. Launch “Settings” and scroll to “Phone
  3. Tap “Apps” and select the desired app
  4. Tap “Storage” > “Clear cache
  5. If clearing the cache didn’t help, tap “Clear data” > “OK

Clear the Cache Partition:

  1. Make sure the phone is powered OFF
  2. Press and hold “Power” and “Volume down” at the same time
  3. When the phone vibrates, release “Power

  6. Press “Power” to confirm the highlight

  10. Press “Power” to confirm
  11. Once the cache partition is wiped, highlight “Reboot system now” and press “Power” to confirm

NOTE: If clearing the cache partition didn’t solve the problems, you can visit this thread for a guide on how to factory reset the phone.

Reboot to Safe Mode and Uninstall an App:
