After unlocking my phone with ChevronWP7 and now my screen goes black during a call and is unusable. The connection is fine, but its like my proximity sensor is doing its job even when the phone is away from my face. I checked and there is nothing physically blocking my sensor. I have to wait for the other person to hang up, then my phone shows the lock screen. I did a reboot but this didn't fix the problem. I don't know if this is device specific but I'm running an HTC HD7 without the software update. Here's everything I did after the unlock:
Prevent my phone from relocking:

Change my theme color:

And lastly installed a couple custom ringtones.
Unfortunately, I can't say after what step this started happening as I didn't get a call until I was all done.
Anyways, If anyone as had this same issue or a possible way to fix it without a hard reset, I'd sure appreciate some help.
Thanks,

the problem is in your sensor.....it's hardware related problem and have nothing to do with software, use your warranty to fix it
Hey guys. Im having a problem with the proximity sensor on my sensation 4g. It was working fine when i bought it. It shut the screen off while calling, but now it does not. I thought that maybe rooting it would fix the problem by getting a custom rom, but i would like some input before i go rom exploring on this phone. I assume its a software issue because i havnt dropped the phone or anything along that line. Any Help would be highly appreciated. I also am looking for the dialer codes that would lead you into a test mode to test the functions on the device. If anyone knows of a code, I would appreciate to learn what it is. thank you for your help.
Make sure Proximity sensor is enabled in Settings > Call Settings > Additional Settings.
thank for your reply. I checked the settings and the only thing that shows up is Caller Id settings and Call waiting. Oh and i downloaded a market app that would show me all the sensors that work on my phone, and the light and proximity sensors both come up with an unknown error. Could it be something from the gingerbread update?
Did anyone figure this out? I have the same problem and its getting pretty annoying.
Me too...:-(
Hello,
I am having the same problem. Earlier, I thought that it was a ROM issue, however, after changing multiple ROMs, it seems to be firmware issue.
On my sensation, I found out that it is related to the back light for the soft keys (home, menu, back and search).
I can get it to work if I turn on pocket mode in Settings > Sound and then restart (once or twice). It will work until next restart.
I have installed AndroSensor from market and it shows one of the 3 messages
Proximity Sensor: Waiting for Event
Proximity Sensor: Unknown Error.
Proximity Sensor: 3.5in
Also, I am getting exceptional battery life which makes me wonder whether phone uses both the cores or if anything else is wrong with the phone.
I am using Energy ROM (3rd Oct).
Any feedback?
Thanks,
Baiju

This is interesting b/c I just noticed I have the same problem, too. I do not check the pocket mode because I want to save some battery life. I did get the proximity sensor working during calls "sometimes". And it's really hard to define this "sometimes" b/c I cannot identify the pattern or reproduce the scenario.
My solution to this issue is that If it's not working, I recharge the battery until full, do a reboot, maybe reboot twice, and it is "sometimes" "fixed" by itself. In my case, after doing that, the proximity will work for a while (again, it's hard to determine how long), and just stopping working all the sudden.
I hope there is a easier fix, maybe a app, that would reset the proximity so we can apply it when the sensor does not work.
Hi I just realized the cause, it's because the battery % mod from UOT kitchen. I removed it and everything is fine now. Apparently the UOT kitchen's setting has problem.
I have 2 sensation 4g. One doesn't have any problem with Energy ROM. For the other phone, I went back to Factory settings and reinstalled original TMobile ROM. I still have problem with that one. I have contacted t-mobile and asked for a replacement. It is something with the hardware I suppose.

hello
I got the exact same problem and i do many rom/kernel change to figure out this problem but i just can't .
Yungyeh could you explain more how do you solve it ? thks

I guess nothing fancy.
As I've known so far, there are several causes, which can be divided into two categories: Hardware and software .
If your device came with this issue, with a stock rom installed, maybe applied some updates, then you shouldn't wait to call the (HTC/T-mobile?) customer service. Have a exchange or replacement is the only way to correct the hardware issue.
If it's a software issue, i.e. it worked before with a stock rom, but now it fails sometimes after flashing a custom rom, you may go with the following solutions.
Situation One: If the custom rom is fresh installed, charge your device until battery full, stay in charge mode for another 1 - 2 hours, complete power off and on at least twice (three times maybe, make sure the "fastboot" in the power settings is off). Do not install any mod until your rom settles for a few hours. Sometimes the sensor does not work will simply because the cache goes wrong. If after waiting for a few hours and the problem still persists, you may want to check your custom rom's instruction and make sure you've followed every steps.
Situation Two: If the proximity sensor does not work all the sudden, especially after doing a reboot, you should first clear your data for phone app (or any other apps that use the proximity sensor), and then boot into recovery to clear all your cache. After wiping your cache, you have to do what situation 1 instructed because your device is just like a fresh installed one.
Situation Three: If your proximity sensor fails to work after applying a mod, especially some mods cooked from the UOT kitchen, revert back to your previous backup. DO NOT APPLY THAT MOD ANYMORE!!! Try some other mods that work for you and that is friendly to your proximity sensor. This situation also applies to if your flash an inappropriate kernel. Revert back to your previous backup is the only solution.
If none of the situations described above works for you, then I am out of clue. Changing to other custom rom or kernel usually does not work. You may try that but I doubt it will resolve this issue. It may be just your bad luck that the proximity sensor of your device goes to its end. I sincerely hope it not the case.
my sensors are not working!!
accelerometer
gyroscope
light
magnetic field
orientation
proximity
All not working...
Was using HyperSensation-CM7.1-v0.8, then decided to update the kernel, faux newer one, then lost the ability to rotate the phone..
So, did a manual wipe, then super wipe, restored my backup, and still no sensors,
wiped again and tried a diffrent rom nothing changed,
wiped again tried arhd 3.6.7 with stock kernel and faux kernel,
tried cm7 with the kernel it comes with or the newer one and still nothing...
at what level does the software talk to these sensors, is there a 100%way to wipe the phone and start over? i have never had any issue like this before!
Would reverting back to the original rom via fastboot help at all versus what i have done?
if someone has any ideas pm me, its a little bit easier then catching a response here since this is the most popular rom in the world lol, but ill still be reading
I'm having the same probpem. I don't really mess around with Roms or anything and I have 2 sensation 4g that do the same thing. And I believe is an htc problem.
having the same iseu with proximity and light sensor.
Do you have an solution yet ?

I`m having the same problem with both proximity and light sensors.They work occasionally but not for to long.Have you found a solution for this?
It's April of 2012 and I have found NO answers or fixes!!!!!!!!!!
Same sensor problem on my sensation.
If I reboot the phone in a dark room, booth sensors are working (I don't know if it's correct when the proximity sensor shows only 3,5 or 0 inches, but it works)
When I go to a lighted room, the proximity sensor stops to work and the light sensor needs more time to measure the illumination.
If I reboot the phone into lighted room, the sensors didn't work.
It is possible to simulate a "dark room" by covering the sensors with a finger ;-)
It is not easy to decide if the error is located into software or the sensors are "overloaded". For finding out a solution I have ordered new flex main board which should contain booth sensors. Hope it helps ^^

@schand99: The Flex/Main Board actually isn't the problem. It is an HTC software/hardware related problem. I have 2 Sensation's here now, one is rooted and unlocked entirely and the Proximity and Ambient Light Sensors and the Capacative Backlights on the touchpad DO NOT WORK. FYI, the touchpad lights work in cooperation of the Ambient Light Sensors: If there is any light under 90.0 Luxes (this is how the sensor measures light) the backlights will come on. If there is anything over 90.0 Luxes, the backlights will stay off. This is based on the fact that you need light in a totally dark environment, or you do not need light as you can see the touchpad and it is not that dark.
It is DEFINITELY not a hardware issue as there are some temporary fixes that will bring them back to life, but usually after a reboot, they are both dead again.
I am curious if your new flex/main cable would do the trick or not. I have tested the sensors chipsets independently and they work fine, there is just something that block their functionality on a software end.

My report about main flex board changing:
After changing the board booth sensors are working fine. I have tested the functionality of the sensors also on different ROM's like stock rom, OrDroid and CoinDroid. No problem until now. It makes not a difference anymore if I power on the phone into dark room or on a sunny place.
BUT!
I don't recommend to do this by yourself. It is verry difficult to do this work !!
It is my profession to do this kind of work.
AND
to change the board was the right method for fixing the sensor-problem on my HTC Sensation. I had to unlock the hboot 1.27.xx by using the "beer drinking" method. So perhaps I have damaged the sensors by doing this...

@schand99: That's very strange that it could be the SAME hardware problem for all of these people that are complaining about this issue. I wonder if is some sort of production issue they have. The strange part is that it is not just for the lot of hardware issued for the USA only, it is also in other parts of the world also.
I did a hardware exchange with mine at the TMOUS store and the "new" one I have now is working fine thank God.
I told them that the TMOUS ICS RUU OTA upgrade broke the sensors LOL!
Thanks for your feedback!
Okay So i've had my triumph for almost a month now... My camera app has had issues since I've had the phone. The Camera app (stock and any other third party btw) when opened maybe the 4th or 5th time throughout the day would just black screen and freeze. So Hit home, force close, clear data and was no cache to clear. Attempt afterwords showed the same result. Would have to battery pull for use a few times and the same result of black screen. So did a factory wipe/reset through Clockwork mod and now opens everytime. Now the issue is the touch to focus will not work under any setting. I was wondering if I reset again?, is this software? Hardware? If anybody knows it would be someone here. Thanks.
might just be defective
id just demand a replacement if i were you man

I would try installing a custom ROM on it such as CM7 (CyanogenMod 7) and if that doesn't take care of the issue then you know it's hardware. You would be surprised how much a new ROM will do for this phone.
This is my first time installing custom ROM's on my otherwise stock Sprint Motorola photon 4G LTE. After successfully flashing CM13 (2016_08_20 snapshot release), I tried to make a call, and upon hitting "call" from the dialer, the screen goes black and stays that way. The only recourse is to hold down power button long enough to reboot. While the screen is black, there is no sound from the ear piece (i.e. it does not appear that the call is connected). Finally, while the screen is black, the phone does exhibit some reactions: it vibrates sometimes if I hit the power button, in other words, the device is still 'on" until I have to reboot it.
After this happened, I gave up on CM13 and flashed CM-12 (the latest snapshot release, from 2015) , and experienced the same behavior.
The call apparently was completed, because the other party received a missed call. However, there was no sound on my end (although there was side-tone, when I breathed on it)
I googled for about an hour, and saw examples of the same behavior on other devices claiming to be related to the proximity sensor (though in those cases, there apparently was audio in the ear piece-- ie. the call completed, and was in progress while the screen was black). This behavior was not observed a few minutes before under stock ROM in the same device (so doubt it's a strictly hardware issue, so doubt I need to open the device and clean the sensor, per some of the suggestions out there).
I suspect the answer is very basic, because I found no similar threads searching XDA.
Please let me know any ideas. I did not do anything about updating my baseband version from stock before flashing the CM ROMs., but don't know if I have to I'm a noob at custom Rom's and just remembered that you had to worry about the baseband / radio version back on the HTC Evo 8 years ago, which was my last time flashing. Again, the ROM itself worked fine-- wifi and 3G/LTE connectivity was a success.
Let me know any ideas.
thanks
After restoring to stock, dialing worked again on the phone, but the behavior on the device was different from two other photons I tested next to it.
In the stock ROM, the call connected, but the screen turned off immediately upon hitting "call" (even when the phone was on the desk). You could get the screen back (in stock only) by hitting the power button.
In my other two photons, the black screen does not kick-in immediately. So it does appear it could be something having to do with the proximity sensor (i.e. it's always engaged). I don't have the skills to confirm. I am writing-off this phone for now, and have a different device (so not a high-priority thread at this point), but let me know if anyone has any ideas. Thx.
There's a way to validate if the prox sensor is working - zDeviceTest in the Play Store will test all of the hardware, and it will also show the metrics each piece of hardware is receiving - the prox sensor being fairly simple, it just identifies if an object is "near" or "far".
I always recommend making sure everything works in the stock ROM before flashing anything custom - as you need to validate everything works before making tweaks.
My advice is the same as arrrghhhs. (This name really looks like it was typed with a Photon Q with some characters repeated by the device >.>)
I noticed that my proximity sensor sometimes "stuck" to near (I use some different app [SatStat] so it shows 3 cm or 100 cm instead of near/far). Winking a little above the sensor helps sometimes. But your problem sounds like a defect.
I have tried every single ROM on this Forum for Moto G 2015 Osprey 1GB version. However I am having same issue on evry ROM . Often I recieve a call my screen goes blank and I am not able to answer the call . Also when dialling out my screen goes blank after pressing dial . As a result I am not able to put teh call to loud speaker or use any other in call options . Can some please help me how to fix the issue . (I know work around to use Power Button to end calls and Volume to answer calls however that doe snot suite me as I ended up answering few calls which i did not wanted while mobiel in my pocket ).
Things I have done so far
I have tried this with both a screen protectoron and now have taken screen protector off . Issue still there
I have a a backup of orignal Motoroal ROM and this issue does not happen on orignal ROM
I have installed Nano gapps to make sure I have unough RAM free issue still there
I have tried most of the ROM 7.1.1 and even 6.0.1 all ROMS including Cynogen mod+ Lineage 13 and 14, ressurection remix, AOPS . Experience, Slim, AOKP, Cosmic , AOSP extended and list goes on and on but issue is still; there
Is there any specific reason for this issue ?
Is this to do with RAM, Sensor or custom ROMS issue ?
Is teher any way to turn teh sensor off which turn screen off whiel in a call and when i take mobile near my face (I am thinking if sensor incorrectly so wanst to check if turning thsi off makes any difference )
Can anyone please help
So your proximity sensor is acting up... are you on current baseband and firmware? I would suggest flashing the latest factory image completely via fastboot, verify operation of the proximity sensor, then flash your ROM again. A backup and restore in TWRP of stock is not sufficient to update firmware.

Thanks acejavelin you are always helpfull. I know how to flash Stock Formware however How can I verify operation of the proximity sensor?
I have found a copy of orignal firmware under XDA thread however I am not sure whether it is up to date firmware or not . How can I confirm if this is up to date firmware ?

Just take the newest one there... Best you can do.
As far as testing the proximity sensor, make some calls and have someone call you... You can try a sensor tester app like https://play.google.com/store/apps/details?id=com.mtorres.phonetester too
Brilliant , Thanks alot . will try that
FACING EXACTLY SAME PROBLEM ON XT1550
I have a common problem in all ROMs I'm installing . whenever I answer a call or dial a call my screen goes off as if proximity sensor is activated and doesn't turn on even when I take it away from my ear or press my power button. Screen doesn't turn on at all during call.
Phone remains fine for a day or two after I wipe cache etc from recovery but again the problem starts. This happens in all custom roms and also in rooted stock ROM. My device is XT 1055.
Kindly suggest any solution as it causes lot of inconvenience.

There is only one fix. find where is proximity sensor, usually it is on the top near front camera . when ever screen goes blank dry your thumb and clean screen with teh thumb where proximity sensor and screen will wake up .
Also you need to keep you pockets extra clean. It is better if you can hoover inside them as most of the time I noticed there was a little dirt always on my screen when screen went blank. I am noit sure if my mobiel screen has gone very catchy to dirt after 1 year use
I intially though iut was due to custom ROMS and I have gone back to stock ROM and recieved two motorola security updated still issue is there so this is not because of the ROM .
Try this
Goto settings and search default from the search button then select phone app and set the default app.
Just saw this and thought I'd try Phone Tester. covered or uncovered, my proximity det always said Far. I tested phone by making a call and then covering it and the screen immediately went black. I would suggest that some screen protectors might interfere a bit but you've already taken that into account. Note where it is (on my xt1540 top just right of ear speaker) and make sure surface is clean. Otherwise just may be defective.
EDIT: if you feel it's "defective" You might consider replacing the screen/digitizer in hopes that that would fix it and it's not a motherboard issue.
Facing same issue
My stock rom on moto G3 2015 was working fine. Yesterday i rooted and installed tesla when this issue started. Frustrated i tried ASOP Extended and here too same issue.
It's not the issue of the sensor since Stock rom was fine till 2 days ago.
Have tried Phone notificaion settings as well.
Any updates on this or else i may have to reinstall Stock ROM
