yesterday my fingerpring sensor (power button) became really hot.
without installing any app or doing some changes.
going to try wipe after backup
has someone same experience?
only the power buttom or the device?
yes. nothing else
quite odd, did you do something before get hot?
nothig. just using my phone
When My redmi note 8 pro finger print scanner became hot, turns out it was a short circuit. Cleaned the sensor and socked and then it work fine.
Maybe the same issue with what occurred to your 10s?

Yes. As the finger print sensor is in the power button, for redmi note 10s
Bro it may be some issue with the power button, maybe some components of sensor or button have weared out, suggest you to visit service center for better assistance.

Ever since my 4x HD was new I've noticed a problem, but it's getting so annoying now I finally thought I should do something about it, and I've contacted LG with a view to sending it off for repair:
When I remove the phone from my ear the proximity sensor usually fails to wake the screen back up, meaning I have no controls to end the call with. Occasionally swiping my finger over the sensors at the top of the screen wake it up, but mostly it takes several attempts, and presses of the screen lock button.
SO annoying when you are leaving someone a voicemail and it's still recording, all they hear at the end of the message is the muffled swipe of a finger and me muttering and swearing at the phone as it carries on recording for another 30 seconds or so!!
Anyone else have this issue??

Mine doesn't awake in the end of calls too... but I thought it was normal
We have an option where we can use "Power button" to turn off calls...
I didn't knew that the proximity sensor was suppose to wake up the disply...
Hi Rudeas,
Glad it's not just me!
Where is the option to use the power button to end calls?

Maybe a really daft question, but I presume you haven't put a screen protector on that covers the sensor? Stone of the cheap protectors do and that would stop it working properly.
Good thinking, but no, I don't have a.screen protector or anything over It.
To test and eventually to calibrate the proximity sensor, you can use hidden menu (dial 3845#*880#) -> Device Test -> All Auto Test Menu Full -> ALC / Proximity Test.
You can even test the "auto brightness mode" (to test also the light sensor) and "enable proximity wakeLock" (to simulate a call).
To test the sensor just put a finger near the sensor.
There is also a "Calibration" feature to calibrate the sensor if needed.

Wow italianquadcore! That is amazing! Firstly I could see by putting my finger over the sensor how poorly it was working. Often it wouldn't notice I had taken my finger away- then I pressed calibrate, and now it notices instantly, every time!!
Thanks loads, I'm assuming it's fixed now!

Thanx a lot, yah it was a screen protector giving trouble to sensor.
Hi everyone.
I've just bought myself P880 as well. But had the same problem as author. However, the fix to calibrate via hidden menu didn't help at all. My sensor doesn't react at all, however, when I am using a hardware test it shows sensor is present.
Do you think there is something wrong with sensor itself, or there might be some android might have failed to initialize driver?
Thanks in advance!
Mine wasn't fixed by the calibration for long. It soon got worse again, I actually damaged my headphone socket (using a really big headphone plug through an 3.5mm adapter, then accidentally knocking it) and ended up buying a new part from etradesupply.com for about £17. The headphone socket is the same component that contains the proximity sensor, so replacing that fixed it.
I had phoned LG, but as I had bought my p880 from german amazon they said they wouldn't have covered me even if it had been a warranty problem (So much for Europe being somehow unified!) so I had to risk taking my phone apart myself!

It works with V20A without any problems (just tested). Please check if you disabled something, regarding hidden menu or some other related items, in app management.
Thank you italianquadcore!
That solved my issue as well...

When holding it, my palm stuck to the front face of the phone and sometime it randomly touch the finger sensor and it vibrates
the scanner is good on the front for quick access but prefer it on the back
How is possible for your palm to touch the sensor in the lower portion of the screen when a normal person will hold the phone in a way the palm of the hand is on the back of the phone???

This is not phone calling position. This is a hold position when simply walking
This must be one of the stupidest complaints I've seen. Of course the FPS will attempt to read your palm if you press it against it.
Solution? Put in pocket or carry phone palm-to-back.
Is it possible to remove fingerprint from aod on p30 pro without removing fingerprint sign in? I can't find settings for it...
I don't know about yours, but mine isn't there until I pick up the phone or touch the screen?
If you want to completely remove it then you can't - the way the finger print sensor works requires the screen to light up at max brightness under your finger so it can capture the fingerprint with the optical sensor.
Watch the 'JerryRigEverything' YouTube teardown to find out more info on how it works, but when scanning for a fingerprint it needs the illumination

I was wondering this too as I'm starting to get slight screen burn from a combination of that and the intense light required to unlock. My S10+ has an option to turn it off, and muscle memory dictates that it isn't really necessary after a few days of use.

As I said above, the reason for the intense light is that it uses and optical sensor rather than an ultrasonic sensor (as used in the S10+). Without the light it simply will not be able to see fingerprints.

I understand that but I'd like to at least be able to turn off the fingerprint indicator. I hold my phone in my hand most of the day so it's a bit annoying that it pops up every time you move the phone. You can switch off this indicator on the S10 and it has nothing to do with the technology - it's just a guide.
I feel there is no proximity sensor in this phone..
Becuase while i am on call , even though the screen is touched to my ear , it will light up randomly as i am walking and turning.
Is that function managed by accelerometer and gyroscope as in new redmi phones ?
The autobrightness is also acting weird for me in some cases .

It doesn't do so for me but yes if I move my face when talking the screen turns on but then goes back off immediately. It seems that proximity sensor is managed by the accelerometer combined with ai just like it was in my old OnePlus 7Pro. However, I could be totally wrong!

While on call I tried to use another phone`s camera to search for proximity sensor ( it is ir based , so camera picks it up).
But couldnt find it

So then, my suspicions are right..It's accelerometer+ai
I think it uses the camera too. If you try unlock the phone with the selfie camera covered, it will try to prevent it.
Likewise, if you make a call with your phone placed flat on a surface, you can get the screen to turn off by covering the camera.

Yes it has one. It's near the light sensor... They are both under the display.

I dont think it has .
Even when i am on call , phone just touching my ear , it randomly lets the screen turn on .
Also as far as i remember , always on display in the previous generations used to turn off when the phone was in pocket ( or screen was covered)
But here , the aod always remains on regardless if phone is in pocket or outside .

Yes you are right. It has an ir based one like note 10,20, s10, s20...
Samsung probably is wondering if they should make it invisible with no indicator. That tiny flashing circle has caused more commotion than a midget hooker in the playpen. Every new model provokes this same discussion... talk about a fixation
Using the camera sensor be prohibitive because of power consumption. It would still need an IR emitter to work properly. Net zero gain... and a lot of added complexity at best.
You can test the light sensor with CPU-Z, cover the space to the right of the front camera, that's also what triggers display dimming no matter what adaptive brightness settings you have.
my S20 FE does the same thing on calls. super irritating... i wonder if Samsung will correct the SD card slot omission mistake on the S22. they did the same thing with the S6 and fixed it on the S7

It wakes up the screen during calls
Hi there. My Pixel 7 Pro shows a strange behavior when my finger approaches the front camera. The screen gets dark even if it's 2 or 3 centimeters away. I'm on latestes beta.
This is very annoying because I can't use a ln app which has buttons on the upper end of the screen.
After a reboot it's fine but after some hours this bug shows up again.
Not seeing that happen to my Pixel 7 (non-pro)
does it occur in safe mode?
hello. I also had this problem a few times quite rarely with the Pixel 7. Once the phone restarted, no more worries. Could it be an application that produces this kind of bug?
It's the proximity sensor. Normally, this behavior should only happen when in a call. Maybe an app is glitching your phone?

I second this. The sensor is under display directly below the camera. Something is triggering it when it shouldn't.
