i dropped my phone in some water and the buttons nor the responsivness to the screen are working correct. however when i take the battery out the sticker on the battery has not changed color showing it was wet. still white with red stripe. if i take it into verizon and tell them it stopped working on me will they be able to tell if water has been inside? and i also have os .113 installed, would downgrading while the phone is not very responsive brick the phone?
