[Q] Digitizer doesn't work after 2nd unlock topic

Hello,

I just repaired a G3 screen and found that now, the G3 only works after the first time you unlock it, when it boots up. It works perfect, but when I press the power button to lock it, then when I press it again, the digitizer doesn't work. No matter if it there's the pattern lock, or anything. Could it be that te proximity sensor is damaged? How can I deactivate it in order to try it?

Thank you
