My iPhone 4s dropped in water...Logic Board issue?
My iPhone 4s dropped in water a couple days ago. I put it in rice and it eventually came back to life. Everything on the device works except for the touch screen. I cannot swipe or anything. Also, Siri doesn't really work (the only response I get when I hold down the home button is "I'm really sorry about this, but I can't take any requests right now. Please try again in a little while." Note: It's been more than a little while since.) I had assumed that I just needed my digitizer replaced.
I took my phone to Cyberion, a digital repair shop, and I was told that there is more damage to the phone than just on the digitizer and my screen is still not in use. The employee there said that it could be an issue with the logic board. Perhaps corrosion?
Does this sound right to any of you? And if so, would replacing the logic board help the touch screen work again?
