My phone shuts off the proximity sensor when I pinch the top left corner, it sounds like the fix on this thread (which is hardware not software related) sounds plausible:

Proximity sensor on my xperia z5 shows always "On" and turns off only when I press upper right corner of the phone. When I type *#*#7378423#*#* I don't have calibration option, what can I do. Any suggestions?

Positioning the tape is touchy, but I was able to restore normal operation on my Z5 Compact.
This method (or a spot of nail polish) could also be used to simply disable the proximity sensor without any other hardware or software hacks.

On my Xperia Z3, proximity sensor was always on (after fixing SIM reader issue). Removed rear cover. Loosened screw at the WLAN antena (it's the one above the USB port looking from the back of the phone) and applied and relesed pressure on the WLAN antenna by hand while checking the sensor in service mode until it worked properly. In the same time, also played with the screw by loosening and tightening it.
