Clear App Cache/Data:

NOTE: If one of your apps doesn’t work as intended, crashes, takes up too much storage inexplicably etc. you can try to fix these problems by clearing the app’s cache and/or data.

  1. Launch “Settings
  2. Access “Phone
  3. Tap “Apps” and switch to “All apps” if needed
  4. Select the desired app
  5. Tap “Clear cache
  6. If clearing the cache didn’t help, tap “Clear data” > “OK” (check the WARNING above)

Clear the Phone’s Cache Partition:

NOTE: If your phone doesn’t work properly and you’re considering a factory reset, alternatively you can try fixing the issues by clearing the phone’s cache partition, which can have similar results to a factory reset but without the loss of personal data from the phone.

  3. At the black screen with blue and red text, release the volume button

  8. Once in Recovery, press “Volume down” to highlight “Wipe cache partition” and press “Power
  9. When prompted to “Reboot system now” press “Power” one last time
