Hey,
I'm having a problem with my proximity sensor. If I make a phone call, the screen turns automatically black, even if sensor isn't covered. And I can't turn the screen back on during call, only if the conversational partner hangs up, then it turns back on normally. If I try to hang up, the phone the display stays black for about 2min.
I'm having this problem only with WP7 & Android, works normally on WM6.5.
Hope somebody can help me.
Thanks in advantage.
You saying it works fine with winmo, it has to be a setting or bad flashing. You can try wiping your phone and starting over. I haven't played with WP7, but in some andriod roms there is an opition to use proximity sensor in the phone settings. Goto settings/ call settings. You might want to check and see. might be able to help you more if you were to tell what rom and how you installed.
This setting montecarlo5 mentions is available in cyanogenmod roms.
Are you sure there's no dirt covering your proximity sensor? Maybe Android is more sensitive than WM/WP.
I'm using RAFDROID HD 2.3 and like u allready said, the setting isn't available.
I'm having this issue on every NAND build i ever tested, but the sensor is 100% clean.
Please guys, don't open everytime a new thread before searching, if some one did the same -.- I made some tests to find out the reason of this issue and how to solve it (more or less).
Pls follow: http://forum.xda-developers.com/showthread.php?t=913134
This is for Samsung Omnia 7 if you have used the Diag app/code to mess about with the settings. I had screwed my rotation by changing some settings. Tried a reset via code but that didn't work. In the end I used code *#2580# to enter integrity control and ensured it was at '1' (on), then use code *#0*# to enter LCD test, lay the phone flat and press the 'CAL' button. It returned 'true' and now my accelerometer works again.
Hope this is actually a fix and it helps someone out. I have noticed a few people lost the rotation on their Omnia 7's. This will probably work for Samsung Focus too. If this does fix your problem let us all know so this can help others too.
Yep - that CAL is calibrate, I imagine. You can also do it with the "Level" application from Microsoft (spirit level thing) if you don't fancy the diag codes.
Diagnostics / Accelerometer (+ fix)
Yes, if you play around in the diagnostics - BE CAREFUL!
To enter diagnostics on your Samsung (confirmed for Omnia 7) enter ##634# and press "call"
Then type the following for the following services:
*#0*# Various diagnostic settings incl accelerometer, compass, screen colour
*#2*# Detailed battery info (incl. charge to nearest 1%)
*#3*# Screen brightness
Be carefull if you choose to calebrate the accelerometer as it will muck up your auto rotation if the phone is incorrectly positioned.
To reset the rotation do the following:
- Ensure the yellow flowers picture is upright (aligned with the flowers towards the top of the phone)
- Lay the phone down on a true horizontal flat surface (XYZ values do not matter for this) ensuring the flowers remain upright
- Touch the "Cal" button. If you get "True Return" you have reset. If "false", try again in slightly different positions until it works.

Thank you !
I am currently experience another issue since I launched that app.
The start button doesn't turn on the display anymore,
maybe I'm getting crazy but I think holding that button was indeed turning the display on.
Actually I did miss my calibration but thanks to your help, I fixed,
do you think the Start button issue could be related to that tool as well ?
Thank you
Would this solve the slow auto rotation of the UI?
I had the HD7 and the auto rotation on the Omnia seems to damn slower and less responive than it was on the HD7

I have the exact same problem for a few days now, don't remember what could have been the setting for it.
Start button doesn't turn on the display anymore. I want that back! How can I get the start button to default?
Thx.
I have just reset my phone to factory defaults : Parameters, About, Reset ...
Notice that resetting will erase everything, I've lost my IE favorites by the way ...
Everything is back, Start button as well ...
In fact I did play too much with the settings, it was turning the screen off
as soon as I was making a call, the only way to turn it back on was the called one to end the call ...
Tried to fix (lol) proximity and lights settings but nothing ...
I think I'll just leave the Diagnostics app. for now, too dangerous
there seems to be an option to do that as well from the app.
But will it erase your data ? I don't know ...

My proximity sensor went crazy too. The fix is to go to diagnostics mode (google for it) and register a bit larger proximity value as a default. I used my hand to block the sensor. On my phone the absolute minimum seemed to be 3, which made the phone unusable. Something in the range of 10-20 seemed to be the most useful compromise. You may need to experiment a bit to get a suitable value. This way you don't have to reset the entire phone.
I still wonder what the default proximity value is... if anyone knows, please reply.
I have Samsung Focus 1.3 Mango 7720, but i don't see "cal" in the settings of the Proximity?
can you help?
Thanks
Hello fancies!
I'm having some problems with the proximity sensor of my Omnia 7. Basically the values from the proximity sensors are a little bit off the usual and the screen just goes black when answering a phone call ( so I can't hang up anymore, for example ).
I tried the diagnosis menu and the LCD test screen. There I can see the proximity values and understand why the phone is behaving this way, but there is no "SET" button as a lot of guides on the internet say.
My guess is that that button is gone with the update to Mango. Anyone can confirm me that and give me an alternative diagnosis screen where to change the value?
The screen I'm refering to is: *#0*# from the diagnosis screen.
thanks a lot!
up... any ideas?

maybe a dumb question- have you a new screenprotector, with covered
Proximity Sensor
the sensor is in the up-right corner
so maybe holding it with right hand you cover it and screen goes blank
happens to me...
it's not what I asked.
I know where the proximity sensor is and how it behaves, but when I replaced the screen something went wrong and the default low threshold is too low to work properly right now, so I have to set another value.
This was possible on WP7, but apparently it's not in mango. Do you have any idea where I can find that setting on mango?
has anyone got an answer to his question?
it seems that there isn't the set function in the diagnosis mode with mango anymore ..
me too have same problem.i just change my lcd screen after it happen when i make call screen is going black andi can't do anything no any button is not working.
there is any way to set promixty sensor on mango ?
or any app for this ?
flash a pre-mango ROM and change the value in the diagnosis app, I'm not sure if it will stick when you update, but it is certainly worth a try.
You can try reinstalling diagnosis app if you haven't yet. Maybe it works.
Hello all.
I have a Samsung focus with an "always on" proximity sensor. So the phone does not light up after it has moved away from ones face during a phone call, making it impossible to use after any call without a restart.
I have tried the following solutions.
1- Soft Reset by pulling the battery and waiting
2- Hard reset using numeric codes provided in the ref threads
3- Using the diagnostic menu.
With regards to the third one. The proximity sensor menu shows that the sensor is always "on" no matter where the phone is. But there is no "set" or "reg' button that I can find with which to recalibrate it, the only option is "exit"
It is quite possible that I am missing a feature or function or I need a new solution. If anyone has any insight that would be really helpful.
Thank you in advance.
Same
I have exactly the same problem. Did you solve it ?
You will need to give a little more information. What os version are you running and what diagnostic app are you running. I think the most up to date diagnostic app is ver(.0103).
1. uninstall your diagnostic app
2. install the diagnostic app again to get latest app ##634#
3. open the diagnostic app and type *#0*#
4. tap the proximity sensor button and see if you see set reg and exit soft keys
Issue with proximity sensor in Samsung focus sgh i917
I have the same problem. My LED screen broke recently and replaced it.
It looks like after the screen replacement, the phone's proximity sensor is always in detected mode [in the diag]. So when ever a phone is made or answered the LED screen goes blank disabling all functionality till the other person disconnects.
I ran the diag but it doesn't give me an option to calibrate the sensor. I tried to install the latest diag tool too but same results. There is only one button, "EXIT".
The diagnostic app version is .0628
OS version is 7.10.7720.68
Please help.
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.

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).

I found all those Profiles no more function due to the issue after I believe OTA to Global rom the latest ( August-2019 )

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.
