I broke the screen of my Z5 (model number E6653, Android version 7.1.1) and had it replaced in a hurry by a small firm near where I was. The phone seemed to be all right, but then I found that on making calls the screen immediately blacked out and the only way to end calls to open answerphones, for example, was to turn off the phone by long hold-downs of the physical controls.
The idiots who replaced the screen had stuck a sticker across the sensors at the top of the screen (I didnt know about them beforehand), and I thought that removing the sticker and cleaning the screen would fix. But no. Now, on testing the proximity sensor as instructed by Sony staff in earlier replies, the sensor itself seems dead -- no response at all, damaged perhaps when the screen was replaced. Questions: (1) is there any was of disabling the response to phone-on, sensor-off? ie to make calls ignore the sensor. Apparently some Android phones have a "disable proximity sensor" under call settings, but not this one. (2) Any way of setting any of the buttons to terminate a call?
Best of course would be a magic way to restore the sensor to working but that seems unlikely.
Thanks anyone who has read this far, and would appreciate very much any advice offered
