Hi! For 2 1/2 yrs, my Motorola Razr V has been great, but today, it inexplicably "turned off" & the on/off switch instantly became useless! I thought "Battery?" until the phone rang, lit up & showed a FULL charge! After the call, the (again dark) screen only lit up by plugging in the charger. "Reboot" to fix this? How - with a dead on/off switch??? "Malware"?? Maybe!! So I searched -- & found YOUR article instead. Your "REBOOT" METHOD -- WORKED!! -- & IT FIXED THE PROBLEM!! -- THANK YOU SO MUCH!!!
