I have the Virgin Mobile Wildfire S. When I wake the phone up to use and after sliding down the unlock bar, the right side of the screen is frozen up. I push on the buttons and nothing happens. When I press a button on the left or the middle and then go back and try the ones on the right then they will open. Very strange and frustrating. Has anyone else experienced this problem? I have returned this phone 4 times already due t it not charging when turned off (it still wont) and now this problem....help!!!
