Even i am facing a similar problem.
I had actually gone out for trekking and a phone got damp by chance,not wet.I cleaned the fone and it was all working well.That night i charged the fone.The following next morning i could see my screen continuously flickering and also the screen was divided into two but the screen touch was as usual.Does anyone have a solution

PS:I have put the fone in rice for several hours.

Please Help
Thanks in Advance!!!
