I have a Samsung 3s and I dropped it in water (not covered by warranty).
The problem is that the screen it not 100% brightness. The annoying thing is it kinda works sometimes when I turn it on, other times the screen is only 1% visibility so I can't see anything clearly.
I have tried to factory reset, I have tired to remove the internal ribbon connected for the screen and clean with vinegar (1 part water, 1 part vinegar) and scrub with toothbrush. Neither had any effect.
I cannot find a consistent pattern that makes it work, and praying does not count LOL
Please advise, I have a Samsung 3s GT-I9305
