Problem with the proximity sensor...

I dropped my N8 in the toilet one week ago, and the technical assistance said that it couldn't be possible to restore it...

So I let it dry for some days, and now it's working almost perfectly, I tested almost everything, wifi, bluetooth, camera, flash, sound, HDMI, and everything is working...

BUT... the proximity sensor is bugged, it detects like it's near something all the time...

When I call someone, the screen goes black instantly because of the sensor, so I can't end the call without unlocking the screen manually...

When someone call me, the screen keeps black, and I can't see who is calling or answer the call without unlocking the screen manually...

And it's really annoying... So I sent it again to the technical assistance, and again they said the cellphone could't be restored, I said that the cellphone was now working properly, I showed to the woman that I could turn on the cell, and asked that I just wanted that they look at the proximity sensor, but I was ignored...



So, does anyone had the same problem? There is any way to fix it? Please help me!

I know that the warranty doesn't cover if water enters in the cell, but I asked to they fix it that I would pay it if the fix wasn't about 25% or more of the price of the cell, but refused...


It's more annoying that I thought, now my alarm rang, and I woke up, and looked to the cell, and the screen was black, seriously, 5:30 AM, I can't think right, I kept looking to it about 10 secs until I remember that I have to unlock the screen manually even to turn off the alarm


If I find the tools to open it, I'll try what you said about Isopropoalcohol, but I don't have much hope...

Thanks, and just one more question, what's the name of the tool to open the N8? It's a torx?
