Apps don't respond

The first thing that comes to mind is deleting cache of the affected apps. If this doesn’t help, clear cache of the phone. The last resort would be deleting app data one by one and doing a hard reset.

####Here is the procedure:

  1. Go to Settings > Apps > All Apps > [Affected App] and choose Clear cache. Do so with all affected apps. Proceed with the next step if your problem is not solved.
  2. Go to Recovery Mode and Clear Cache. Proceed with the next step, if your problem is not solved. Attention: The next steps involve the loss of user data. Do a thorough backup beforehand!
  3. Go to Settings > Apps > All Apps > [Affected App] and choose Clear Data. Do so with all affected apps. Proceed to the next step, if your problem is not solved.
  4. Do a hard reset. All your data will be deleted, and the phone will be set back into factory state.

Please come back during the process and tell us how it goes.
