My two lateral "buttons" on the bottom of the screen don't work anymore on my Samsung galaxy ace.
yesterday it was working really slow, almost non responsive so i shut it down and when it turn it on again i had on the screen "safe mode on". Never seen that before and i don't know what it means. After that all my synch were gone and two buttons don't work anymore( turn back and options "buttons")/ Can you help me with some info?
Thanks a lot
