-   i had the same problem on a used one i just bought. first i rebooted and it was fine, but then i checked the four leaves that they have on the phone that touches the battery. Check if they are bent and touching properly, best bet is to be more gentle, i am not sure why this specific phone is so sensitive.-   Guest
