Hello, escuse post in Setools section , o have replaced one touch screen Sony E2105 , but when i start a call the phone disconnect the display and don’t turn on, but the call continue, to disconnect the call is necessary remove battery. I have entered in service menu , proximity switch , the cross talk value is around 13000 , if I put the finger in proximity sensor the value have oscillation 40000 - 45000 , someone have this phone and could check this values in a full working phone?

Best regards Hugo.

This is strange , in my phone now I have , Cross talk 6100 not detected , if I put the finger the value is cross talk 18000 and detected , the detection is on when cross talk is around 7000 , anyway during the call if I put finger in sensor the display continue lighted . Any ideia to solve this?

This is more strange , in same chassi (in same front display+touch) I put one other motherboard , and with the “new “ motherboard I read diferent values , without finger the cross talk is around 16000 detected , and with finger the value is around 30000 and continue detected. In this phone I have replaced the front module (display+touch+frame) initially I think is problem with proximity touch sensor space but now with diferent board have a big diference in values. There is any way to adjust the proximity sensor ?
