Clear the app's data
If the OTA update is for a specific app, then clearing the data for that app can resolve the issue. However, please note that any data saved in the app will be erased.
To clear an app's data, head to Settings > Apps (or Application Manager, depending on your device). From here, tap the app you are experiencing problems with, then choose to clear data.
If you continue to experience the same problem after clearing the app's data, you may need to contact the app's developer.
Uninstall the app
If you continue to have issues after clearing the app's data, you can try uninstalling the app. Please bear in mind that all data stored in the app will be erased. To uninstall an app, touch and hold the app you want to uninstall. Then, drag the app to Uninstall displayed at the top of the screen.
If you don't see Uninstall, then the app is likely a system app that can't be uninstalled.
