Re: why is my galaxy tab 2 going beserk?

Welcome to Android Central! You probably installed some adware/malware inadvertently, most likely along with some other recent app. Try the following:

1. Backup or sync all important data.
2. Go to Settings>Backup & Reset and uncheck Automatically Restore.
3. Do another factory reset.
4. After the Setup Wizard, go immediately to Google Play and stop any apps that might be automatically installing.

Now see if the problem occurs. If not, then start reinstalling apps one by one, watching closely for that issue to resurface.
