Hey, I'm currently using CyanogenMod 6.1.1
In the past week when I am on a call, and I take the phone away from my ear, the screen does not turn back on.
This means I cannot disconnect the call or call anyone or do anything.
It remains off even if I press the power button, volume buttons or circle button.
If anyone has any ideas on why this is happening or how to fix it I would really appreciate it, Thanks!
It's the proximity sensor. Did you replace the screen recently?

Yes I did, I thought I did so correctly but I guess not.
Any idea what could be wrong? Is there a software setting I could set it to just look at orientation not proximity sensor??
You didn't install the tiny rubber cover for the proximity sensor, it won't work properly without it.
You can either fix this or someone posted a hack to disable the sensor a while ago on here. Search for it.

I am currently having this problem, and in the process of finding a replacement for the rubber cover... I just wanted to post a TEMPORARY work around for anyone that runs into this problem:
If the phone is set to keep the screen awake while charging, plugging in the phone (USB or AC) will return the screen after a call. You must have the phone unplugged first (making a call while charging requires unplugging the phone, and then plugging it in again)
Hope this helps anyone with this issue
There's also a temporary fix that you might find useful: just hold it up to a light. Flash the light in the top right corner. Doesn't matter whether you hold it under a lamp, use a flashlight, I even use my bic lighter to activate it. The screen will then turn on again.

Hi everyone,
funny thing happened to my Mozart. Whenever I make a call the screen shuts off like it should, but it doesn't turn on again when i remove it from my ear until the call has ended.
Which works fine if the other person hangs up, but it means I can't hang up. Whenever I reach a voicemail i have to take out the battery to hang up!
First i thought it was a rom issue, i had just gotten my hands on the mango beta when i first noticed it. I thought it might be buggy.
But the problem remains after hard reset and flashing with a different rom (pre-nodo & nodo).
I found out that the sensor still works. The screen is reactivated when i shine a bright light (halogen spot or so) onto it - but only for as long as the source shines onto the sensor, else the screen shuts off again. wierdly enough, direct sunlight doesnt seem to be enough to trigger it anymore.
since i upgraded my phone with a 32GB microSD I guess I'm not eligible for warranty, huh? but im pretty sure it happen long after and i didn't accidently break something while opening the phone.
very weird... any ideas?
I had this problem on the weekend.
I removed the matt screenGUARD, and the problem disapeared.
Also you can reactivate the screen by pressing the on/off button...
thanks for your comments.
unfortunately, I don't use a screen protector and the standby-button doesn't work during a call
I have this problem also, with stock 7392 rom. The sensor seems to work when dialing, but stops a short time after a call is connected.
The power button works for me to turn the screen back on however...
Where is the proximity sensor ?
where on the device is the proximity sensor located?
I have been having difficulty with the screen not switching on during phonecalls and I have to remove battery to end outgoing calls. Pressing the power button doesn't help either. I don't have a screenguard to remove.
The problem started not long after, but not immediately after my daughter dropped the phone down the toilet. It took a few days for the phone to gently dry out and it worked again except for some residual water between the screen and the glass.

The sensor is about 1 cm to the top and right of the htc logo. It's barely visible and it is dark violet. (Or something like that, I am not very good at naming colours.)
Anyway, I sometimes also experience problems with sensitivity with HTC Mozart, mostly during calls, especially when the proximity sensor has been activated. Sometimes the home button freezes after a call... It's a bit annoying.
During a phone call, my proximity sensor doesnt seem to be sensitive enough. The screen turns off when I hold it to my ear, but when I pull away to look at the screen and interact with it, the screen either doesnt turn on or it will flash on and off again repeatedly. It seems that the phone cant detect that it is not near my head any more and should turn the screen back on.
Generally it wouldnt be a big deal since the screen does turn off when its held near my head, but when I needed to use the dial pad for a menu prompt it got really frustrating when trying to press in numbers with the screen switching on and off. (I just called Verizon CS recently and navigating through the menu was a pain with this screen going on and off).
I'm coming from the Samsung Charge which was very responsive: when you pulled the phone away from your head, the screen instantly turns on for you to press in keys or hang up. With the Rezound, it doesnt turn on most of the time and I have to press the power button (which will turn it on and then automatically off again...). The problem is alleviated if I'm in a very bright place (direct sunlight) so my guess is that the proximity sensor may not be sensitive enough to detect the difference between darkness and low lighting conditions. I'm sitting in a room with a 26W CFL lamp (so not too dark) and the Rezound has trouble turning the screen back on during a call when I pull the phone away from my ear.
Was wondering if anyone else exhibit this condition or if its just specific to my device (in which case I'll have to give Verizon a ring to get another replacement)?
I'm having the opposite problem. It unlocks itself a lot up against my head. My thunderbolt did this so bad I got a replacement thinking it was a defective proximity sensor. But it wasn't and I got in the habit of manually locking the screen on calls. But now my rezound does it but not as bad. I think htc sucks with proximity sensors cuz auto brightness is never programmed properly. It doesn't go dark enough compared to Samsung and motorola phones with auto brightness on. It only has about 3 brightness levels like in the HTC brightness widget, whereas stock Android has 5.

I'm having the same problem. The sensor would force the phone screen off as soon as I make a phone call. The verizon rep had me hard-reset while I was on the phone with her. The same symptom arises after the hard reset and the phone is brand-new.
I had to reset to get her to send me another rezound replacement.
On this replacement, however, I'm having the same issue again. My gf's rezound doesn't seem to have the issue.
I'm having a second replacement sent now. This is pretty annoying.
The interesting thing is the issue comes and goes. One day the sensor wouldn't respond, and other days it works fine. Although I would say that the issue deteriorates over time and never improves.
Had to do a battery pull last night. Had my phone in my pocket for probably an hour, when I pulled it out the screen was black. LED would flash ocassionally and I think I heard a text so everything was fine except the screen. I have Always On off, and I require either fingerprint, a pin, or OK Google voice recognition to unlock.
Tapping the screen, hard pressing or fingerprinting the power button, volume buttons all did nothing. I guess there's a dialog for powering off the device so holding the power button didn't reboot it either. Eventually pulled the battery and it rebooted fine.
Anyone else had this? Pretty disappointed. Haven't installed any new apps in the past few days. I've heard (and had once) a related issue where the phone takes a lot of presses to turn on the screen—in that situation, Always On is on, it's in your pocket so the phone detects and turns off Always On, and for some reason when you pull it out it very infrequently takes a little while to come on. No idea if they're related.
Do you have a screen protector, skin or case installed? Maybe it's causing issues with the sensors in combination with something else?

Have a case and a glass screen protector but they are not new.

This just happened to me yesterday. Dropped the phone, and it stayed on but the screen is completely black. I opened it up and tried re-setting the display ribbon cable, but that didn't do anything. Anyone have any ideas what the problem might be?
Another thread about this stupid sensor.
My screen goes black when I call or answer a call. If I use a headset sometimes randomly the screen comes on or stays on when I answer a call.
The proximity sensor is working. Looking in *#*#7378423#*#* > Service tests > Ambient Light Sensor.
Putting it to a lamp gives a value of 10.0 and putting my finger over the sensor gives 0.0 .
So its working.
This seems to not be rom related if not for the change after Android 4.4. I flashed roms from cm-12.1-20161016-NIGHTLY-togari.zip, AOSP_N_161207_togari.zip and now I am on hybrid_concept_edition_2.0.zip.
I do have a screen protector on. But with a hole for the sensor. Its not dirty in that area. And the sensor worked fine way before I installed it.
This started happening during the last two months or so.
I tried numerus of apps from play store. None did anything. Of course I could force the screen to be on. But with the risk of pushing some buttons when I'm in a call.
My temporary fix so far has been to enable end call with power button
Do you have any idea what to do?
Thank you
I'm facing this same problem, I'm on stock.

yup.. I had mine apart today. But you need to remove the battery in order to flip the motherboard around to get to the connector.
I don't have time for that. Perhaps the battery will explode if I try to remove it..
So I cut a piece of foam plastic to fit around the usb connector so there is a constant pressure applied to the motherboard when screwed down the NFC antenna because there is a screw just around this area that sets the NFC antenna in place.
Hang on. I just made a call just for the sake of it that you answered to my thread and it freakin works!!!!!!!!!!!
I got the idea from this guy/gal: https://forum.xda-developers.com/xp...olution-proximity-sensor-fix-z-ultra-t3595525
Hi guys,
so I'm having a minor (maybe major) issue with my device. I'm (was) running the Resurrection Remix Oreo without problems. I did have an annoying problem with my proximity sensor tho (black screen when making a call, up until now I used the power button to hang up).
I tried to disable the sensor using sensor disabler from the xposed framework. After reboot I tried making a call and my phone shut off.
No LED, no falshmode, no fastboot, no vibrating after holding down power+volume up. Any idea of how to fix this?
Any help would be much appreciated.
Cheers
Edit: Got this fixed by simply de- and re-connecting the battery. All good!
How did you get to the battery if I may ask?

Oops, im sorry, I overlooked your reply. You have to open the backcover to get to the battery. It's really easy, just heat the back up a little using a hairdryer, carefully lift the cover at the top using a suction cup and try to get underneath it using a plastic pick (a butter knife also does the job if you're careful). After you're in, just work your way around the back cover until it comes off.

Sorry again for the late reply!:angel:
