Samsung galaxy tab 4 locked in an app

[Richiehorkan]

Hi, my Samsung galaxy tab 4 is stuck in an app, have rebooted and still comes back into the app, can work the app but won't return to home scree or anything else

Did you actually turn the system off and on fully? A program should not just pop up on it's own unless it's a virus.

If it does, you should do a factory reset which will wipe the system to like it was new, it will wipe your settings and files so you'd have to restore it from backups.
