Proximity Sensor broken? - Galaxy S II Q&A, Help & Troubleshooting

Hey guys,
it seems my proximity sensor stopped working. I noticed that my display doesn't turn off anymore when I put the phone to my ear.
I already installed phone tester and in "Sensors" it shows for proximity sensor only "waiting for data ...".
Does this mean I got a hardware defect or is there any other way to reinitialize the sensor somehow?
thanks,
boba

Have you tried any other fws?
Dial *#0*# and select sensor option.. Hide the proximity sensor with hand,.see if there is any response..? Do this relaxly and report back...

Hey,
no there isn't any response on the prox sensor values, they stay at "null ADC: 0(0,0,0)
I am on stock XXKK5 right now, no modifications at all. Before I was on CM7 where I first noticed the sensor is not working.
Anything else I could try before returning the phone for repair?

Null is actually a default value , meaning that no object is in the radius of the proximity sensor. If you put a finger over the sensor the screen should turn green and the value will be over ~200. Try that.
also go to settings -> call -> Turn on proximity sensor and see if its ticked. if its not , tick it

I tried all of that ... but I can't get any reaction of the proximity sensor, no matter what I do :-( I guess I'll return the phone for repair tomorrow, running out of options here ....

I've seen threads around the web with people complaining about the sensor too. Some guy said he took it to repair , and they changed the entire front panel including the sensors. I guess these things do happen sometimes, bad luck bro. Hope it goes well

Hey , Just now i got into your thread via Google ... I am also facing the same proximity sensor issue. Could you please tell me what u did? Gave it for service ?? How is your phone now ??? Waiting for answer.. thanks...

[Q] Proximity sensor fail

Hello!
I have a Sony Xperia Z2, and I was very satisfied with the device until I made an upgrade to the Android verion. Since then, the proximity sensor has issues, is working for a while, after is not working. When I restart the device, it's working again, but not always. Also, the gyroscope is having the same problems. Can all this be because of the software? I am running 23.0.1.A.3.9
I've always had issues with the touch pad waking up when I'm on a call. It hasn't annoyed me enough yet to look for a solution.

try repair via PC Companion
I've tried... The problem is still there. I've made also a factory reset, without results. Someone told me that a custom ROM will fix it, or maybe the update for Android L. It is obvious that is a software issue... Annoying!

Have you attached a screen protector recently? Try downloading the app "Proximity Sensor Finder" on the playstore. Does it count up continuously even if you're not holding your hand on top of the sensor anymore?
I never used any screen protector. I installed this app, Proximity sensor finder, now the sensor it's working (I mentioned that it has periods when it is ok and when it's not). What it seems to be unusual at this app it's that it gives only the minimum and maximum distance when I approach my hand to the sensor.
Also, after a restart, the sensor stopped working. Another restart, it's back on. Could be something from the software?

This is what Proximity Sensor Finder app says when the proximity sensor is not working.

Try disabling "double-tap to wake phone" and test again. Go to Services Test > Proximity Switch by entering *#*#7378423#*#* to test proximity.
Default is OFF, but when you cover the proximity sensor, it will display ON

For me, it just stays ON indefinitely, but sometimes it turns off. Weird

[Q] L9 II D605 problem with proximity sensor

Hello, until i replaced my broken touch screen, my proximity sensor is not working. When I am calling, My display is turned off all the time. I was looking for apps that could help me (with calibrate proximity), but no one helped. I am using CM11 V9
Could someone help me with this problem please? Thank You. MP
Firstly chek if sensor is working at all, dial this code in your phone: 3845#*605#, then search for proximity test or buttons test, i dont remember.

when I did it, it said Problem with connection or invalid code MMI. I have great connection so it means my proximity does not work?
Im not an expert in mobile phone hardware, but i think the problem is with connection/connector

My screen turns off during call, and can't turn it on during call

I have this issue with my S3, that is infuriating! Whenever I get a call and answer it, my screen turns off after a short while and during the call I can't turn it back on. The power and home buttons do nothing, and the proximity sensor isn't working either, so I can't turn off a call.
Anyone know how I can fix this? I have Lollipop, CyanogenMod 12.1 custom ROM installed.
Thank you for your time.
This bug partially exists in stock roms too. It's just magnified in custom roms.
You should be able to set it to keep the screen on during calls. It's the only way i know of.
I fixed this problem by opening up the phone, unplugging the proximity sensor, and throwing it in the bin. (the trash to you Americans)
Screen stays on during calls now, but I've not had problems with accidentally ending calls with my face, so I'm happy.
You also lose your front camera because it's part of the same tiny PCB. But I've never used the front camera on a phone in my life. So my solution is perfect for me, but maybe not for you.
The other option is a software fix. There's an app, or a method that you can do yourself to disable the proximity sensor, but I had problems with it, so did it my way.
Edit: I forgot to mention that the reason my proximity sensor wasn't working was because whoever had this phone before me did a screen repair and had half severed the ribbon cable for the proximity sensor by accident. Not just because of the bug that sometimes exists.

Proximity sensor problem. Manually calibrating it solved the issue for me.

Go to that thread and follow instructions. The code for sensors might be different for s3, Google it.

Bah, that's the boring way to fix it.
(didn't work for me. maybe work for OP though)

I remember that I saw a MOD or xposed module to keep screen on during call.
It's better than throwing the sensor to the bin (trash ) .

Proximity Sensor Issue in Miui and CM roms !!!

Hi All
Any one facing proximity issues here , i saw so many peoples reported in mi forums that when we make a call screen blacks out when we moved to ears( Thats normal) and won't turn back again , so i have to wait the other side person to hangup the call or screen won't turn on power button does work that time, i think this only affects with Sensortek stk3x1x sensor, Redmi note 3 pro comes with two proximity sensors one is from Liteon and other is Sensortek.... Liteon sensors doesn't have this issue, for temporary fix "Wipe proximity area with a cloth or reboot fixes this and it comes back after sometime....( Calibrated but same it works for sometime) no idea wats causing this , issues there in Miui and CM roms....
I found sometimes a flip case with a magnet can cause issues like this when folded right back against the back of the phone, the screen won't come back on because it thinks the flip case is closed.

yeah but i don't have flipcase, this sensor issues starts with those have "Sensortek Proximity Sensor" Liteon doesn't have issue i think....
Flash the rom again using mi flash tool u will find that yr issue will be solved
Or go to test mode amd calibrate the sensor... that's all
Fastboot flash persist persist.img from latest miui rom? I recently had a problem with sensors. The above cured all
@Hemphiz i think that method for dead sensors bro, this one working sometimes it doesn't mostly if we flash a new rom and use no issues but if we reboot the phone after sometime issue starts.... @ra.one i did that bro flashmiui and recalibrate sensor but that works for temporary please check which sensors you got from this app from playstore https://play.google.com/store/apps/details?id=imoblife.androidsensorbox
if you got Liteon Sensors mostly no issues with proximity, if u got Sensortek u will be having issues or once u got issue it will come back..... im not sure why is causing that..... this is really very annoying bug.... Thousands of people reported in Mi forums about these proximity issues on various devices even on newly launched Redmi 3s/ prime may be they have all got "Sensortek Proximity Sensors".......
This is not a bug, You can disable Prevent Pocket dials under Settings-->Lock screen-->Prevent pocket dials...
I had this since last miui 6.9.9 flash.
Disabled prevent Pocket dials and All is working fine
Edit: for a few hours it was working.
Now its the same again. Phone blacked Out After a call and wont turn on, After a few seconds its coming back. As i said , since flashing new 6.9.9

like i said it may be mostly an issue with Sensortek proximity, can u check which sensors u got from this app https://play.google.com/store/apps/d...droidsensorbox
I have sensortec.
But i think its Software related.
Its since last Update.
I calibrate the Sensor and the issue with calls is still there.
Sensor Works fine, test is okay.

Yes i think its software related but, one trick works clean flash the same rom and use it for a week without any reboot...... (DO CLEAN FLASH and Dont reboot the phone)
don't need to calibrate.... for me when i install new rom and use it for a week no issues , if i reboot the phone the issue starts after sometimes.... i don't knw wats causing it so many peoples with sensortek having issues and this bug is not resolved from Miui 7 to Now Miui 8 MM, the issue there in Custom roms im using RR rom i have issues....
Guys For those having issues Check which sensor you got from this app, if u have proximity issues while calling its mostly "Sensortek"
https://play.google.com/store/apps/details?id=imoblife.androidsensorbox
We need Permanent fix....
I also have exact same issue and i have sensortek sensor. But i can unlock the screen while on a call by pressing power button and then unlocking with fingerprint. Bit annoying

So its confirmed its an issue with Sensortek Sensor, no Liteon users reported here, like i told flash the same rom which you are in (clean flash) and don't reboot phone for a week there will be no issues it works perfectly, if u reboot a phone once the issue starts again after sometime so after reboot something is going on no idea what....
i am using this app(for rooted users) on official RR and it works fine

even me used, but i don't think its properly working..... this issue starts only after a reboot, when u flash new roms and after boot dont reboot or power off the phone for a week, not needed any apps, proximity will work properly but once u rebooted issue starts....
But this app's settings load every time phone boots up.so it will work after every boot.
press thanks if I helped u in any way

yes this app i tested earlier, but after sometimes may be in a day or two it won't work....
Found another related issue with proximity , i think proximity is not working properly when there is not enough light around us something related with ambient light sensor i think ..... Eg: if we are in a dark room proximity won't work correctly turn on the light and try it works properly.... i think Xiaomi messed up with something with both sensors Liteon and Sensortek thats why Liteon users face Gyroscope lag in games in dark room and now i think may be the same reason why proximity not working properly in dark room....
hello. I have the BUG but my phone has sensortek version 1 (not 2)
When in a call the screen wont turn off when placing the phone at my ears. With whatsapp the bug wont happend.
I think this is a BUG related to sensor + phone app
A functional workarround is to dial, then press menu (putting the call at background) and then putting the call at foreground again. It works 100% of the time.
Any news? I have this annoying problem too!

Sensor Issue

Hi, I got my Mi 3 this week. I noticed some weird behavior from my magnetometer and Accelerometer, wondering if anybody else is experiencing the same. After a day of use, sensors go haywire and suddenly stop reporting data. Can't use compass and my auto rotate stops working. I tried different apps to see if it's a global problem or just a not compatible app, so far when sensors go blank, the effect is global. Even the Mi self test is not reading anything from the sensors. Pedometer is on the other hand operational tho.
Things come back to normal after a restart. I suspect it must be a software bug maybe?

My sensors are working but they are wrongly calibrated :/ and pedometer isn't working! I thought the pedometer was disactivated by default...

Dial *#*#6484#*#* it's the built-in test. U can recalibrate your accelerometer there and also test the device. Use power button to exit. And for +-45 test's of the accelerometer tilt your device on it's corners.

Thanks for the tip it works perfectly!
By the way, you are using European firmware or Global, because for me the pedometer isn't counting the steps :/

I'm glad to hear it worked for you. My pedometer comes and goes... Not reliable unfortunately. btw how can I check my ROM region? Got the October patch, It doesn't solve the bug...
I also have problems with my vibrator. It doesn't react to short vibrations (that much I can make out of it).

Well I seem to have the global version. MIXM
I hope they get problems solved fast.
If anybody else with the device is reading this post, can you please check your sensors with an appropriate app and see if yours is also malfunctioning randomly?
I had this problem, but I just restarted the device and everything came back normal

Yes! It goes away with restarting (and sometimes doesn't!!!)
But it's just a temporary fix, in matter of hours, you r back to the square one.

Go to Accessibility settings and turn on Touch Vibration. Keeping it off also hinders the in call volume function. Hope it helps

Well yeah, it did work actually. But the thing is, I don't like to have the touch vibrations on always, I just want it to work with G-board and some other apps that use short vibrations as a feedback...
It's like the touch vibrations setting, controls everything lol.
It's definitely a bug they have to get fixed.
So it turns out the sensor problem that I reported is being caused by the G-cam port I had installed. The solution is to close the app (in the multitasking menu !?) Whenever you are done using it.
Flash the stock rom again and your problem will be solved for sure, also faced the same issue.
I have same issue and flash stock rom but still not working how can i fix it ?
I also have a problem with compass apps. north and south are correct shown, west and east are not correct.
