i just got a call and i kept touching "speaker"... i don't have any screen protector. Plus the autbrightness sometimes doesn't work :S
Well i just blew on it a bit and clean it and now it seems to work.
I dont know if its a software thing or bug, but when the brightness goes up because there is more ambient light, when there is less ambient light it takes a while for the brightness to go down, or sometimes it doens't and I need to set it to low then to automatic again
