The front face buttons dont work, just under the touch screen, the home button, settings, back, go and enter button, right at the bottom of the base. not the slide out keyboard. I have rebooted the phone several times, if I slide out the keyboard I cant use the buttons under the screen. yet my slide out keyboard buttons work just fine. i hope its not dead and its time for a new phone because I only like phones with keyboards, I hate touch screen keys. Do I have to buy a replacement part and is it hard to repair yourself?
