It's not the hinges because the outside screen still works,everything works great when its on the charger,and you can take it off the charger, and works fine but as soon as you close it, it reboots? Im not techy like that. It's a software error of some sort. My loss your gain I paid it off it was like 1400$ Txt or CL chat or email only. NO CALLS PLEASE!!!!!
