In need of help, dropped my samsung s3 in the garden pond for about 10 seconds. Phone was still working so took it apart quickly to let things dry. Switched it back on and the screen was flickering. Took it apart and has been left for about 4 days in pieces also left it in a bowl of rice to soak up any moisture I keep putting it back together and EVERYTHING works except the screen it won't seem to flick on. Speaker works, I can hear messages and emails going off but can't see anything. Got the misses to ring me and it rings and I even swiped it to answer the phone and that works. Just wont show anything on the screen. What do I do from here?
