Hi,
Dear friends to day i am going to share LG Optimous Vu F100 restart solution. for how to please see video below.
Symtoms phone restarting again and again but when you put charger then working normally. phone start restarting when batter gone under 50%. Optimous Vu start restarting when you set screen brightness to full.
Solutionturn off phone and open it carefully. disconnect battery and try to remove sticker from battery connector side.
you will see little chip inside then short big resistor with a wire and you have done.
Ok Good Luck Friends.
