For the last 2 or 3 months I've noticed my proximity and light sensor don't work on my Focus 1.3.
The screen doesn't turn off while on a call and the camera button can wake the phone with the screen turned off.
I've also seen that the screen doesn't auto dim any longer when in a dark room.
I held off on doing the warranty swap with ATT because I thought Mango might fix it but I haven't had any luck.
Do you have any suggestions?
When you mean the camera button wakes the phone up, does it launch the camera app, or is it like the power button is pressed (when the screen is off)?

That I have seen was a setting I had in the camera settings but the rest I've seen still stands.
Diagnosis app
So basically you need to recalibrate your proximity and light sensors with the diagnosis app. Please read the sticky thread for diagnostic codes. This issues has been discussed. Off the top of my head I can't remember the codes how to do it. I would search the forum for proximity sensor and light sensor recalibration.
Update-
1. If you don't have the diagnosis app you need to type ##634# in your dial pad
2. type *#0*# - diagnosis app not the dial pad
3. Recalibrate the Light and the proximity, then restart your phone. Should be fixed.
As for holding the camera button and the screen lights up. That is an advantage/shortcut to get to picture mode. That setting can be disabled if you go
1. Windows home live tile screen
2. settings
3. Swipe over to applications
4. pictures + camera
5. disable press and hold camera to wake up the phone or enable prevent accidental camera lauch when phone is locked

So this should work for both?!
This makes me very happy! I'll report back soon.
Huh when I get into the Proximity recal it only shows XXX (No Detection) and never changes anything.
Am I doing it wrong?
EDIT: The value reported for light is staying at 0000 too.
http://forum.xda-developers.com/showthread.php?t=1045167&highlight=proximity
Is hinting that I have a busted set of sensors and will need to warranty it.
play with the set and reg button. Also, restart the phone to see if it will work. Not to insult your intelligence but you know where the proximity and light sensor are right? Hold your finger in front of it on it moving it further and closer. If none of these work you might have defective sensors. I like to try everything a couple of time before I take it in for warranty.
I do know where the sensor is, right next to the earpiece.
I've restarted the device and tried the sensors again but no luck.
When I try to set the light value at something I get some error about "Light_SetCalValue : DeviceloControl failed" and for the proximity test the screen always stays red even if I cover the whole phone with my hand.
I'm in the same boat. I've been debating on just rolling all the way back to stock and starting all over. Of course if it is a hardware issue I'm just going to be wasting time. Then again it probably would be best to roll back before sending it in on a warranty issue...
My other concern is if they do cover it what am I going to get back? Don't really want to be stuck on a Rev 1.4 focus as that STILL seems to be causing issues.
I hear ya tanders04, it would stink to get a 1.4 back.
Also, thank you siralex241 for the help.
Hi,
i've always the pb of proximity sonsor or somthing in that field when i'm installing a custom rom of android 6.0, 7.0 or 7.1 such as (OptimizedCM-14.1-20161121-BETA1-AROMA, JDCTeam_jdc_jflte-7.1-20161117-BETA, MK60.1-jfltexx-201605070057-NIGHTLY)
so when i make a call, via messenger or my sim dialer, the screen turns off and won't turn on if i push power or home buttons.
so, what's the solution of this pb i'm suffering from, from a long time...
Does the phone work properly on a stock ROM? Did you try disabling the proximity sensor or disabling the screen-off function?

Yes, i'm now on 5.0.1 (stock rom) it works fine
how can i disable the proximity sonsor or the screen-off function?
This sure looks as a problem with the proximity sensor, the s4 is known for accumulating dust and grease on top of it. Open your phone with a small Phillips tool, remove it and clean it. It will work as new.
Don't think it's a hardware problem since the sensor works properly on a stock ROM.
Sorry, I no longer have an s4 and I don't remember how to disable the proximity sensor in a custom or stock ROM.
Hello. I recently replaced my nexus 6p screen and now surfer the dreaded proximity sensor problem. On 7.1.2 i was able to use torch when longpressing power button when screen is off. (this is via custom rom function. No tasker) now that ive upgraded to oreo, that function is gone even if the rom supports the feature. Im guessing something to do with prox. Idk. Anyways can someone guide me into making a task profile/task that whenever my screen is locked or off i can use torch while long presing the power button? Thank you so much.
Not sure if you read into it, but the broken proximity sensor problem after screen replacement is likely due to a missing rubber grommet over the prox sensor. It falls off or sticks to the old frame. Can't help with Tasker tho
Bollux. Any other work around while im on lockscreen? I mean i know a big change happend from N to O but that big where i cant utilize torch because of a proximity problem? N didnt do it Why does O have to. :'( i mean even with the broken prox on N i was able to utilize torch while screen was off.

Not sure sorry. I have used Torchie from the play store. If i remember right you turn on torch by pressing both volume buttons
I guess my dream of making this work is crushed. Please delete/close this thread mods. Thank you very much.
Hi.
I have problem with proximity sensor. While making a phone call, display is always on.
I tried to enable it in settings. Turned it on, rebooted my phone and nothing happened.
Also tried *#*#6484#*#* solution, and when I open proximity sensor, there are 'test' and 'error' buttons on the screen and I can't click anything.
Does anyone know how to fix this?
In the engineering menu * # * # 6484 # * # * we find 27 - Proximity sensor
When approaching the palm to the front camera should show "0".
I always showed "5", did not want to be calibrated.
I pressed Error, went out and went to the engineering menu, a miracle happened - it was calibrated.

No, nothing happened. As usuall, screen is always on.
Yes, proximity sensor in settings was on and I have rebooted the phone.
I really don't know what to do. Is it because of bug in Global Rom or is it hardware malfunction?

Hold your phone with your left hand. The placement sensor gets blocked by your right ear when you make calls using your right hand. Give it a go and get back to us.

Ok, non-related to left and right hand.. Now my phone gets black screen all the time during calls. I can't put it on speaker or do anything while talking with someone. I really don't know what's happening...

I can't help there but left/right holding is an issue I guess with this phone. Or maybe it's the Pro. I forget offhand.

Obviously the proximity sensor is at fault. Enter the menu using the code mentioned above, then press the menu/options button and select Calibrate proximity sensor. Once you're there, hold your hand over the proximity sensor (to the right of the front camera) and tap the Calibrate button. That's one thing that could fix it.
Failing that, go to incoming call settings and turn off the proximity sensor (turn off screen in call). Restart your phone, go to the same toggle and turn it on.
If neither of these works, you likely have a faulty piece of hardware. Your last option is to have the phone repaired or try a different kernel/ROM.

Hi , are you on miui global stock rom? Or custom rom?
I just had the same issue , but in my case , I recently opened the bootloader and installed xiaomi.eu rom, everything was working fine. I got notification of update ,I downloaded the update , but flash it thru TWRP , and then with the new update, the proximity was not working at all. Flash again the new rom, but wiping everything , and now works.

Is the EU rom that better?
I mean is there any plane to compare the known issues between the global and EU ?
I'm using the miui global 10.3.3.0 PFGEUXM and definitely have some "issues" with the proximity sensor.
I'm still trying to tie down the exact nature of the problem:
With a quick test, or doing calibration, it seems to work exactly as I would expect; the screen switches off as you approach closer than about 2 inches.
However during a long call I notice the display start to flash "on" frequently in the corner of my eye and soft keys can get inadvertently pressed.
It kinda feels like it gets worse during the call, is it time or perhaps the phone warming up in my hand? Not sure.
hi @All!
is there still no permanent solution for fixing proximity bug?
its really annoying and making me crazy....
even after making it working again using quicktune app - doing one call it is broken again

Exactly what i've experienced.
Super annoying when you accidentally hang up during a call.
It happend countless times so far.
I'm on eu beta btw.
Wish there would be a solution.. . But afaik proximity is even more bugged in non miui custom roms.
I had this problem to. my proximity sensor what not responding at all. I thought it was defective because the calibration was not working to.
Then i went to the system update settings, downloaded the latest package and flashed it. After reflashing it started working with no problem at all.
Factory reset did the trick for me. Working normally now.
Install Quick Tuneup. Then do Sensor Celebration & Restart your device twice.
Two solutions

It turns out that the problem is because MIUI does not activate the proximity sensor when the smartphone is turning on.
To force MIUI to ALWAYS activate the sensor at each start, we can do two things:
1- Always have "Automatic brightness" activated
2- Activate the "Pocket mode" (the best choice)
After applying one of these situations, it is necessary to restart the phone.
Only by activating the pocket mode it is no longer necessary to have automatic brightness activated all the time.
In the video I show how to activate the "pocket mode"

I published this solution in a forum in my country (Colombia).

above is proof to SOLVE the Proximity Sensor no reaction in my Redmi Note 7.
I was having lots of TASKER Profile depending on whether or not Proximity Sensor is covered.
I found all those Profiles no more function due to the issue after I believe OTA to Global rom the latest ( August-2019 )
Thanks again to KMILO_PARRA

Actually, the proximity sensor for Redmi Note 7 isn't in the "usual" top-center position, it's a little bit on the top-right edge (if you watch the phone "against the light" you can actually see a small dot on that side).
If you're calling\responding try to put your ear at that angle, you'll never have those problem anymore.
I know it seems crazy, and of course the first times could be "unusual" to put the ear there, but it actually worked out flawlessly for me.

It works for me
Hi guys,
I have made a little workaround, using the suggestion of @KMILO_PARRA user. (pocket)
https://taskerprofilecenter.blogspot.com/2019/09/project-proximity-sensor-workaround-for.html
This is mainly for Tasker users, but I have generated an APK to be installed too. So any user can use it. But what is needed, by now, is root, as it needs to write to Settings table.
Please, report me back if it does the job or not.
Note1: For those users that don't know how Tasker works, just install the app, and give it root permissions, and allow Write System Settings permission (Android option). I recommend you to not set it as an app to be killed from the OS using the battery optimization, as it could be killed. It acts on every shutdown and device boot.
Note2: It will generate two permanent notifications: Place holder, and the one that is the mini-Tasker code monitor (required). Just, disable the Place holder one, as described in the same notification (click on it), and disable notifications completely for the installed app to get rid of the last one.
---------- Post added at 12:44 AM ---------- Previous post was at 12:31 AM ----------
What it does exactly?
Well, as I explained on my web, it just changes the value (0/1) from the 'enable_screen_on_proximity_sensor' Global Settings table, that makes the pocket option to be toggleable in an automated way.
So, be sure not to use that option as a daily one, as the project/app uses it to allow the sensor be available at startup. And do not forget that you will need root too! Sorry.
What to download if I don't know what Tasker is?
You will only have to download the APK from the 'Kid App (APK)' link, provided under the 'DOWNLOAD' section. Nothing else.
If you know Tasker, you will know what to do.
Does it work really?
I'm currently testing this workaround, but as I could see, at least on my device (lavender too), seems to be working as expected. But needs to be tested a little more.
So, if it does not what it's intented for, please, report it me back.
After installing the app, giving root permissions, and allow it to modify system settings, reboot the device to take it effect.
