Re: Proximity sensor issue resolved :)

I have just fitted a tempered glass screen protector. I now have this issue with my proximity sensor.

I cannot find where to download the old operating software from (x.x.x.534) to calibrate the sensor with. My software does not have a calibrate facility just a test.

Can anyone suggest where the download is available from please?

Also if I calibrate it to work with my screen cover then download up to date operating software will the phone then revert back to not working using the new software or will the sensor be calibrated and stay as it is?

There will be no point in all the effort if on the next software upgrade it reverts back to not working!

Re: Proximity sensor issue resolved :)

Well apparently several things including third party apps or screen cover could cause this issue of ‘having the proximity switch constantly ON’. However in my case (I have Xperia Z Ultra with Lollipop) the issue is hardware related. As many already suggested here, the proximity switch’s chip is located somewhere close to the proximity sensor inside the phone. If you happen to put enough pressure on that area then your proximity switch becomes off and it works fine afterward while you are still applying that pressure. Apparently those who are lucky, by keep having that pressure for few secs the switch’s chip slips back into its position and the problem would be resolved. However for me, unfortunately, as soon as I remove the pressure the switch turns back on! You can check that by dialing *#*#7378423#*#* and then in the Service Menu go to the ‘Service Test’ and hit the ‘Proximity Switch’. If you have the same problem your proximity switch should appear as ‘ON’ there. When you apply that pressure somewhere around the sensor ( mine is on the back close to the NFC logo) you would see on screen that proximity switch is going OFF. Hopefully after you remove the pressure it stays off and you would solve the problem this way, but if you are not lucky like me then you could either do the hardware troubleshooting by literally having access to the proximity chip or try the dummy thing that I do (but works every time) , which is pressing that same area on the back of my phone when I want to hang-up and then bring the phone down from my ear and disconnect the call or have access to screen while I am still on the line!

Hy. I haver the Xperia Z C6603 Lollipop. And the proximity switch is not working on the calls. I've done the service test *#*#7378423#*#* and appears "Off". It is a hardware problem?
