Clear App Cache / Data:

NOTE: If one of your applications crashes, freezes, takes too much space inexplicably or is otherwise unresponsive, you can try fixing these problems by clearing the app’s cache / data.

WARNING! When you clear an app’s data, all personal data stored within the app, including login and credit card information, profiles, high scores, settings etc. will be lost. To avoid losing data, clear only the app’s cache.

  2. Open “Settings
  3. Tap “Apps
  4. Swipe to “Downloaded” or “All
  5. Select the desired app
  6. Tap “Clear cache” > “OK
  7. If necessary, tap “Clear data” > “OK

Clear the Cache Partition:

NOTE: In case your phone doesn’t work properly and you’re considering master resetting it, you can try clearing the phone’s cache partition instead. This can yield similar results as a factory reset, without losing any of your personal data stored on the device’s internal memory.

  1. First, turn off the phone
  2. Next, press and hold “Volume Up” and “Power” at the same time
  3. When the screen turns on, release “Power
  4. Wait for the Android System Recovery menu to appear
  5. From the menu, navigate using “Volume down” and highlight “Wipe cache partition
  6. Press “Power” to select the highlighted option
  7. Press “Volume down” to navigate “Yes – erase all user data
  8. Press “Power” to confirm

NOTE: If clearing the cache partition didn’t solve the problems, you can visit this thread for instructions on how you can factory reset the device instead.
