So my son got an Alcatel One Touch Idol X last month (I know it's a two years old phone but he's also just 13) and this morning, it started vibrating on its own and won't stop. Screen is off and won't turn on either, When it's plugged, the 'charging' LED (white LED) does turn on.
I looked on the web and couldn't find a way to reboot the phone (like on BB10, holding both volume rockers for 15 seconds will reboot the phone), only how to do a hard reset (power and volume up), It doesn't work. Can't remove the battery either.
Unless somebody has a better idea, our only recourse is to let it drain and hope when recharged, it will be ok.
OS is Kitkat 4.4.2 and the only thing that happened maybe an hour before was the installation of "Popup Notifier Free" and the removal of "Echo Lockscreen".
