Dropped my Samsung Galaxy J5 (SM-J500Y) in water about three weeks back. It worked fine until Monday last week when it rebooted itself and froze on the boot screen. After removing and reinserting the battery, it either rebooted and froze, booted completely and froze on the lock screen or booted completely giving me full use except that the screen touches were delayed and the screen would time-out as it usually does and light up again automatically. Full use usually lasted 30 minutes at the most then the recurring problem of automatic reboot started once more.
The battery is still chargeable which brought me to the conclusion that the motherboard is faulty and maybe the digitizer as well. Could you please offer you insight to possible problems and solutions?
P.S. Is it possible to interchange motherboards of different models of the same J5 series? (i.e J500F with a J500Y)
