Why is my Samsung galaxy ace 4 not allowing safe mode to be removed

[AC Question]

I tried restarting, then removing my line and battery for more than 2mins and even resetting it but all was in Vern

Welcome to Android Central! Do you notice if there are problems with your Volume Down button? If it's stuck in a pressed state, then that will always force the phone to boot up into Safe Mode.

Also, are you sure it's Safe Mode, or could it be Factory Mode, like in this video?
