Clear App Cache / Data:

NOTE: In case one of your apps doesn’t work as intended or takes up too much storage, you might be able to fix it by clearing the app’s cache or data.

WARNING! When you clear an app’s data you will remove all of your personal data stored within the app, including credit card and login information, profiles, high scores, saved games etc. As such, you should first try fixing the app by clearing its cache.

2. Open “Settings” and scroll to “Phone”
3. Tap “Apps” and access the “All” tab
4. Select the desired app and tap “Clear cache”
5. If necessary, tap “Clear data” > “OK” (read Warning above)
