Light goes on by herself
I have a Sony Xperia C2104 and it keeps turning the screen on automatically. I lock it, and after a few seconds the screen will light and stay on for a long time

Luz acende sozinha

Tenho um Sony Xperia C2104 e ele fica acendendo a tela automaticamente. Eu o bloqueio, e depois de alguns segundos a tela acende e fica acesa durante um bom tempo
