Clear App Cache / Data:

NOTE: In case one of your applications crashes, freezes or otherwise doesn’t work as intended, you can try fixing these problems by clearing the app’s cache and / or data.

WARNING! By clearing an app’s data, all personal data stored within the app will be lost, including settings, save files, credit card and login information, high scores, profiles etc. To avoid losing personal data, clear ONLY the application’s cache.

  1. Open the “Settings” menu
  2. If necessary, access the “General” tab
  3. Tap “Apps” and swipe to “All
  4. Select the desired application and tap “Clear cache
  5. If needed, tap “Clear data” > “Yes” (Read WARNING Above)

Wipe the Cache Partition:

NOTE: In case your phone freezes, crashes, runs out of storage inexplicably etc. and you’re considering factory resetting the device to solve the issues, you can try wiping the cache partition instead. This can yield similar results to a master reset, without losing any personal data. To wipe the cache partition:

  1. Launch “Settings"
  2. Access the “General” tab if necessary
  3. Tap “Storage
  4. Wait for the device to calculate the data
  5. Once done, tap “Cached data” > “Yes
  6. Wait for the cache partition to be cleared, and review the amount of cached data

NOTE: If clearing the cache didn’t fix the problems, you can visit this thread for instructions on how to factory reset the LG V20.
