so i have the xtc kyocera phone from virgin mobile. And iv always Had problems with this phone so iv been getting the same Replacement phone. well now, my screen wont turn on, but all the buttons light up and it vibrates when i get a text. the screen use to come on ever once and a while but now it dose not. the phone is fully charged but the scree will not turn on. its pitch black. and i can not get a Replacement phone because its over warranty.
