Many common problems with Android apps can be fixed by clearing the app's cache or data. Clearing the cache deletes temporary files, while clearing the data removes all of your settings including log-in data.
- Press your device's Menu button | select Settings (or System Settings).
- Tap Application Manager (or Apps).
- Tap the app icon you want to repair (uKnowMobile).
- Tap Clear Cache.
After completing these steps, check if the uKnowMobile app is working properly. If uKnowMobile is still not working, repeat steps 1-3, and then tap Clear Data.
Keep in mind, clearing the app's data will remove any custom options and settings. It's the same as uninstalling and reinstalling the app.
