My screen goes black when I am in a phone call and it does not turn on unless I hold the power button or something like that. I have already went to the proximity settings to test that it is working.
Any ideas?
Firmware version? Seems to be a bug in last firmwares. Also had this issue some time. Now it seems to be gone.

.In the process of backing up my phone atm to try a factory reset. I'm on latest T-mobile version though.
How did you fix yours?
Bump. Anyone? Is there a fix or is my sensor faulty? Because if it is I can still send it back in for a replacement. Sometimes it will work fine, and sometimes it won't.
I've got similar problem. When sensor is activated, it's keeping activated even if nothing is in front of sensor, so I have to wait for other side to end a call.. any suggestions?
EDIT: problem solved-> I just cleaned the glass on proximity sensor, maybe some dust was there

I also have a problem with phone's proximity sensor. With me, it shows some signs of work right after i boot up the phone. In service menu (*#*#7378423#*#*) -> Proximity switch starts with On value and then goes Off, On, Off, On.. a cycle of at least one minute. The interesting thing is when i cover the sensor it stays On, which means it detects its working. I suppose the sensor is faulty, as I tried several suggested methods to resolve this issue: pressing firmly on top of the sensor, factory resets, reinstalling the software with Sony's PC software kit, some applications from Google market, etc. None of them helped.
As I bought my phone 2nd hand, I see the upper speaker is pressed on its left side a little bit, as if the phone was dropped exactly on this spot at the speaker (which I find is almost impossible, as the front panel is perfect without scratches or anything) or somehow it was pushed with some sharp object. I explained this as it might have a link with the proximity sensor issue, or it may not be connected to it, not sure.

First time poster, though been a regular lurker.
It seems I have a slightly dodgy proximity sensor. Have checked with one of the proximity sensor apps and while the sensor detects if I have my hand over it, it is very unreliable when I take my hand off. It can take from anywhere from 1 to 30 seconds or sometimes never.
While ive been through other threads where people have a completely failed sensor, does anyone have this intermittent problem. Also is this a hardware or software issue.
Im currently htc-dev unlocked running Pacman v15.0.
Out there is a tool for recalibrating the sensor, but you would need to be S-OFF I think and it's done with a service tool (a special PG88DIAG.nbh)
Let me know if you are willing to try it, but it is VERY dangerous if you do the wrong things.
I had the exact problem from the very beginning. Got a phone and the very next day had a screen protector applied. For a few days proximity sensor created problems. The screen would go black when the call started, but until the call did not end, there was no way to bring the screen back. So, I used an app just like yourself to check and saw the same thing happening. Ultimately read extensively and realised it was due to screen protector. Took a scissor and cut off the protector above the sensor. A few months later when I had a new protector (of a different company) applied the same problem reappeared, so I had to cut it off from the top. Except that this time around I was sort of expecting it. I hope this help! :fingers-crossed:
I had the same problem and it continued no matter whether i remove the protector or cut the portion....im unable to most awesome ROM's.......only n sense 4.0 im able to re turn on the screen using power button.if there a way to completely disable this turn off during calls irrespective of the ROM its highly appreciated......
Looking forward for the solution

An update to my situation.. I ordered a new proximity sensor on e-bay and have replaced the same on my phone now. While I was at it, I cleaned up the window as it was pretty grimy and could have been the source of trouble. Also cleaned up the contacts with Isopropyl alcohol. End result.. Im still having the same problem!!
Im pretty sure now that its not a hardware problem and has to do with the calibration. What I have noticed that the sensor works fine in bright sunlight but not when there is less light around. Also am not using a screen guard!
Would it be possible to guide me to the right tools to recalibrate please?
Sorry, I haven't done this myself, but I'll search a bit how it's done by HTC.
They are using a special holding station where the devices are calibrated.
It is normal for display to go blank due to proximity censor while making calls. In my case however,occasionally the display stays blank even after the call gets over. This also happens every now and then when I lock the phone, only to never unlock. At times, the displays backlit switches while unlocking but not all the time. The phone's processor stays awake in both the cases (calling/locking) and the phone rings & vibrates perfectly on making calls. The only option that I have in such cases is to restart the phone. Is anyone facing similar problems with their phones? I've done a factory reset off late but still the problem persists.
Are you using a screen protector? May be you haven't aligned it properly and hence proximity sensor detects it and turns off the display??
I've had similar situations happen to mine, but I figured out that after a Skype call on my phone, the proximity sensor will remain active and will sleep the screen if something's covering it. I'm not sure if you have skype running, but if you do, that might be why.

I don't think obstruction of the proximity sensor is an issue since this problems occurs even when I lock and then try to unlock the phone. Also the backlit turns on at times when I try to unlock the phone.

Well, what you're facing right now is a classic example of what people face when they keep on the protective covering used on a new phone when the phone is shipped.
If you think it's not the issue then search for any apps which you might have installed? Run the phone is safe mode and see if it acts up? Flash stock images or do a reset to rule out the possibility of a software issue.

After few days of working flawlessly, today again the display blanked out while it was locked in normal mode. I tried unlocking the phone but only the backlit would light up. So I restarted the phone, activated the safe mode as suggested by you and then few minutes later, again the display blanked out. What should be the next step now? Please elaborate on flashing stock image. I've earlier done a factory reset but I immediately installed all the apps.

Well, if you're facing the issue in safe mode as well, any apps might not be causing it. To flash factory images, you will need to unlock the bootloader. Follow the guide which is linked in my signature.
Since you don't know about how to flash stock images, I assume you haven't rooted and undervolted? Display black outs while unlocking the device can be caused due to undervolting as well.
It could be a hardware problem on the phone I had before the n5 with my lg g2

Possible, but he should exhaust all software options before seeking out a replacement.

Hi,
I recently replaced my cracked screen and all went well, expect that now the proximity sensor doesn't seem to work 90% of the time. When I make a phone call the screen goes off and it won't come back on when I move the phone away from my face. Either party has to hang up in order to get the screen back on. I've opened the phone up and double checked the ribbons and cables, everything seems ok.
The sensor itself appears to be fine, it's connected direct to the motherboard by the looks of things. I've wiped the phone completely just in case it was software related but that hasn't helped. Has anyone got any advice on how to fix this? I guess I could try to source a broken One S and replace the motherboard, but I don't want to spend too much on getting it working.
Any troubleshooting advice most welcome..
Cheers...
Mines been doing this since the htc repair centre had it,but its got a lot worse recently, proper random though it will work say 10% of the time.
I can't help with the sensor but I set the power button to end calls, its in the accessibility tab in settings, does make it impossible to use the key pad for options on phone calls though.
I seem to be having an issue with my proximity sensor. At times it works 100% which leads me to believe it's a bug in the marshmallow update, since it never happend before it. Sometimes when making a call I can't hang up, the only thing I can do is force reboot the phone. Anyone else with this issue,or should I send it in for repair.

No it happens to me too since the update, very rarely but very annoying!
I'm on the UK Generic version if that makes any difference...

I'm on the same firmware
Really annoying indeed. I wouldn't say rarely in my case, 70% of the time I'd say... Hopefully it gets solved asap!

I find if you give the screen a wipe where the proximity sensor is when it happens, it usually sorts it out. Maybe it's just over sensitive or something...

Has anyone found any solution? This is annoying me too much. Sometimes even when I tap play in music app, the screen goes black.
I have the same problem which began instantly after updating to build number 32.1.A.1.185, and this happens to me every time I place a phone call. Running the Ear Proximity test has it vibrating constantly (meaning that it detects the ear). If i wipe the area above the proximity sensor before running the test and then run the test with nothing near the sensor then it will remain off - but then when something approaches the sensor it kicks in and then never switches off even when you move away from the sensor.
Seems like they have quietly fixed it through some update because it is working fine now.
Completely same problem here with same behaving, but with build 32.2.A.0.224. Any solution?
I mean as farooknaji wrote...
same problem here!
Where is the proximity sensor. Could be my panzerglass (tempered glass screen protector) pressing on it leading my phone to think its againt my ear?
Same problem here since last firmware update! I contacted sony but they say is a hardware issue :S
Do you guys know a way to fix it? Its pretty anoying
I had this to, after I placed a extra glass screenprotector.
Removed it, no problems any more.

When I try to pull down the notification bar on the right the screen goes black. Also turns off the always on display. I'm assuming it's something with the Proximity sensor. Tired of all the little bugs and problems with this phone. I’m returning it. Just curious if anybody else is having this problem.

No, mine isn't doing that. You might have a dud.

I've had that happen on my Pixel 2 XL. Only once or twice and restart fixed it every time.
It's definitely the prox sensor. Always On Display shuts off when the phone is in your pocket or face down, which is detected by the proximity sensor, so that's totally normal. As far as it happening on the home screen, it seems like the phone thinks you're in a call, which would use the proximity sensor to turn the screen off near your head. I would reboot as @jimv1983 suggested and see if that works.
Are you using a screen protector? Sometimes those can cause issues with the proximity sensor, but usually it just causes the screen to shut off and not come back on during a call as it senses the protector at all times instead of your face.

I had a case with a built-in screen protector on it and I thought that might be what was causing it but after taking it off it still did it. Weird thing though once I put it on the wireless charger it stop doing it. Hasn’t done it all day even with case on. Weird. Still thinking about taking it back to Best Buy and swapping it out.
I've had a similar issue where the proximity sensor will not deactivate as long as a call is going (can't hangup, can't unlock, can't speaker phone, can't mute, etc.). I have to wait for the other person to hang up. Get an automated robo-call you accidentally answered....oh well, guess you have to listen to them. I have never been so angry at a phone as I am with this one. Especially as expensive as it is. I absolutely would NOT have bought this phone if I knew ahead of time how aggravating this would be! Thinking of sending it back. BUYERS BEWARE!

Had this very issue with my pixel XL and blowing on the top speaker grille of dust with compressed air solved it.
But if this is out of the box that sucks. It should not be like that. My pixel was approaching two years when that happened.
