My girlfriend dropped her phone and broke the screen. When powered on all the other buttons work. I believe there is still touch sensitivity, but I can't tell for sure. Also, this phones usb port is broke for charging. When I use the special fast charge cable/usb 3 cable that came with the phone, and use that to connect to my computer using usb 3, the phone vibrates like it connected although no screen pop-ups on my computer. There is no screen lock/password locking the phone so thats not a problem. If I press the lock button and swipe like im unlocking the phone, then double tap the home button the voice command turns on so it seems like the phone is unlocked. I believe that all that needs to be done is switch to MTP on the phone. Im not sure how to do that with a black screen though. Is there any way to remotely switch it? Or am I going to have to just try and "imagine" where the button on the screen would be. The phone is At&t if that matters any.
