Right after I replaced the rear camera in my phone it seems like the proximity sensor died as when I try to call the screen immediately turns off and locks until the call has ended.
Proximity sensor finder indicates that there is an object 3cm away but there is nothing actually there and the indicator is just stuck on 3cm.
What should I do?
I'm on cm9 btw.
Bump
Same issue
I have my stock camera and run CM9 AOKP, and I have similar issues with the proximity sensor. I read somewhere that it was an issue with CM in general and always discounted it as such. I did set up volume rocker wake and use that to wake the screen on call.
Do you use facelock? Try disabling it. Its a well known bug in CM9 that effecting proximity sensor...

Using the volume buttons doesn't wake the phone.
Note sure what facelock is.
Thanks for the answers.
my wifes proximity sensor started acting up along with many other problems. this all happened right after the last OTA update. I sent it in to moto for repair. I was suprized i didnt need a reciept. I bought it on cl used. went to motos site and they showed me how to check if warranty was still good
Phone was imported so no warranty is available.

Ok, I figured and putting the proximity sensor really close to a light source makes the screen wakes.
Also, using proximity sensor finder I did see that the proximity sensor responds when putting it really close to the light source.
It seems that while replacing the back camera, the rubber cover of the proximity sensor fell off. Is there any way I can replace it or improvise something that might suite?
Thanks.
Hi Everyone
Clarify me about something that is atrophying my mind. Does the proximity sensor exist on this equipment? What I want to say is this: when I am reading something on my cell phone, and when I'm not having any interaction with my cell phone (because I'm just reading), and how I have configured the settings to turn off the screen in 15 seconds. My question here is ... just because I'm in front of the mobile phone or just waving to the screen does not turn off (something I did in my Moto X 2014) why does it turn off? Should not it stay on because of the proximity sensor? I was using ROM Lineage 15.1 and I thought there was something wrong with this ROM in the proximity sensor, but I went back to the ROM stock and I noticed that I still have this problem. I was thinking that either this phone has no proximity sensor or it is simply broken. I bought this cell phone a week ago. Please help me solve this issue of the sensor.
Thank you

sometimes the indisplay Fingerprint sensor stops working at all.
The display wont recognize any touch and stays black.
If i push the Power button it starts working again.
This happens sporadically, 1 -3x a day
Did anyone had the same Problem?
Any suggestions?
Thanks for reading....
No one?

I haven't seen this problem. I use face unlock along with it and it usually recognizes my face before I can even scan it.
When the screen is black, you can put your finger on the display and some glowing circle Appears. This does not appear to me at all. The screen just stays Black.
Thx for the information.

Maybe your fingerprints got erased somehow? Does your phone display a fingerpring icon on the screen a second after you turn the screen off?
Sent from my LYA-L29 using XDA Labs
Yes the second I turn if off it shows a fingerprint sensor. Just after a while it won't toggle the sensor if I touch the display. It's like the fingerprint sensor is deactivated. The second I turn the display on manually it appears again.
Hello! I've got the p20 pro and now I'm testing mate 20 pro. Sometimes I'm not able to unlock the mate with my fingerprints at all. Same finger. The p20 works perfect, just touch and unlock. Mate sometimes I have to touch it 3-4 times before it unlocks , sometimes it doesn't unlock at all? Is that normal? The display was exchanged already because of this issue.
I believe you guys are not the only one. This on screen finger print is not reliable. I guess because they are new and will improve over time. Personally I just use face recognition than finger print. They are a lot more faster and accurate to unlock.
I know it's an old thread but it's happening to my M20Pro right now! It's awful! The screen is protected by a tempered glass made by Spigen (maybe this glass has issues?). I reconfigured the fingerprint and I touched almost 50 times until the phone captured the fingerprint! What's wrong with that sensor?!
I had problems with glass protector, if you can get plastic film it is fine, glass you will have problems....this was my finding
Possible brightness/proximity sensor issue

If you still have this phone and problem: I have a P30 Pro, and/but the reason I write here is because our phones share the fingerprint technology, and I didn't find anyone mentioning this problem regarding P30 Pro. So:
I have the same problem - seemingly sporadically the fingerprint sensor (or screen) wont react until I press the power button. Then I noticed that when the brightness/proximity sensor (located near the top right on the P30 Pro, and next (right) to the upper speaker on Mate 20 Pro) was covered, the screen would get unresponsive. I guess this is by design, to not accidently let your phone come to life in your pocket. The problem was/is that the proximity (?) sensor is way too sensitive - any obstruction at about 2 cm (0.8") above the sensor(s) will trigger this behaviour. I also think it can be triggered under other circumstances; I had som weird fingerprint/screen behaviour in a store with a high and very dark ceiling, but I have to test this again, so don't take my word for it.
Anyway - if anyone is having sporadic problems - see if this could be a reason.
Edit: Well, sometimes my screen is just totally unresponsive even without sensors blocked, so ... I noticed it a couple of times after digging my phone out of my pocket, suggesting it could still have something to do with the sensors turning the screen (functions) off. I'll try to see if I can make it behave the same way in other scenarios.
I have also been experiencing similar problems on my mate 20 pro, But mine is more of an accuracy problem. sometimes its on point and registers instantly. and other times it just doesnt at all.
However i have noticed that in extremely bright weather i have more issues, fingerprint doesnt read at all, and face ID is also doesn't. My finger print issues have started only after EMUI 10.1, so i suspect that it could possibly be a software related issue
Has anyone else had issue with the finger print sensor responsiveness, in particular with unlocking the phone. Sometimes it is super sensitive and I unlock the screen on accident and then sometimes its completely unresponsive and I have to unlock via PIN.
Usually after unlocking with PIN, finger print sensor works fine for unlocking.
I can confirm this behavior. XQ-BC52 with 61.0.A23.20

I've had the same problem with with older xperia 1, XZ and pretty much all the phones with fingerprint sensor.
when my finger are cold, when in the summer i'm a little sweaty, after eating something i have difficulty in unlocking phones. it's. a limit of fingerprint sensor.
also if for work you ruin a little your finger sometimes you have to register again a new fingerprint

Same here, also on the same model and firmware. But as opposed to @Evil_Sephiroth , I never had such issues on my older phones (Samsung Galaxy S7, Galaxy Note 9).
However, the fingerprint sensor seems to be a bit more consistent than how it was in September when I first got my Xperia 1 III. I hope they'll continue to improve it since it is still very inaccurate and frustrating.
Also, since the fingerprint sensor is always on, it would be nice if we could expand the status bar with a swipe on the fingerprint sensor. This was possible on my old Note 9 and it would be a nice feature on the Xperia 1 III since it's a really long phone.
Hi,
I have problem with the proximity sensor, that automatically start other calls.
How can i solve the problem?
tks
I don't know if it can be calibrated or there are some rom where it works better, what I do to mitigate the problem is turn off the screen after I answer/start a call.

Why are you convinced it's due to the proximity sensor?
The proximity sensor does nothing during a call other than turn off the screen when the speaker comes close to your ear.

Probably because screen stays on during a call and you do all sort of crazy things with your ears.
Calibrating proximity sensor from my experience does very little to help with this problem.
What @MrCrayon suggested is probably the best solution

So the problem is that it doesn't turn off the screen and touching your face to the display triggers what you don't want.
The proximity sensor of our phone has a very narrow detection area. The space is located in the area below the top speaker outputs (top left). The ear should preferably be attached at this point during a call. So not in the middle of the top edge of the phone as usual. It is definitely uncomfortable. In addition, the sensor is less responsive if the phone is not in a vertical position. The proximity sensor is probably the biggest weakness of this phone.
The best way to check its function is to use the AndroSensor app.
