proximity sensor always on

Hi guys m facing a strange issue. I have observed that sometimes my proximity sensor remains on. I tried to find out the app causing it by Force Stopping each app one by one but that doesn't solve the problem. .
I am not using any motion like quick glance which uses the sensor or any other app like turning the screen on off (eg smart cover etc)
only a reboot fixes this issue but after sometime (say few hours or 1-2 days) the sensor turns on. . Can you suggest me what else shall I do? coz m observing more than normal battery drain in stand by mode. . Please help!

Try turning off "quick glance" under settings--> motion.

So it helped a lot are you using custum rom or stock? With stock I only have this on when quick glance on. I helped a lot too :s
Kalgan :s

m using stock rom and kernel...and I am not using quick glance..my phone's proximity sensor remains on even when the screen is on (unlike quick glance)

me too same here dagnamit

I too have noticed it and posted it on a thread also
I also notice this..only now i came to know that it is proximity sensor..will appear as a dim red right and if it stays on, it turns off only if restarted..might be a bug..should we report it to samsung so that they will fix it in updates?

I have noticed one thing that after 2+ or more (random) days of usage if I receive/make a call the sensor doesn't turn off. .might be this is a s/w bug. .but this is what I have noticed after closely monitoring my phone. .

I've noticed this too! Didn't know the dim red light was proximity sensor. But i've noticed it only twice (with battery below 40% on both occasions).

Viber has a known bug that cause the proximity sensor to be always on. If you uses it, u need to update to the latest version i think its v2.2.3.109.

Got the same thing, however i didn't notice it affecting battery life whatsoever, still an awesome battery life.
Still, I would love to see what's the cause of this and how to resolve it.

I have the same problem

I don't know y but I turned off "Increase volume in pocket" in settings and rebooted my device and the problem didn't return since last 4 days. . strange!

Even though I first got this proximity sensor bug after I turned on "increase volume in pocket" (only 1 time so far), I'm pretty sure it's not related, because I did a few tests and as far as I could tell the phone increases the volume based on its position (and possibly movement) in the second it receives the call. If it's vertical (like in a pocket), or on its side (like in a bag), when you get a call, it will increase the volume. If the phone is horizontal, like on a table, and starts ringing, the volume doesn't increase, and it won't increase even if you pick it up and move it around while it's ringing.
I also thought initially that it uses data from the proximity sensor, but I tested and it doesn't care if it's covered or not when the phone rings, it appears to use data from the accelerometer/gyro exclusively.

I'm try turn all motion off right now. Let see if it can solve the problem

I have the same problem.
I resolve it by pressing volume up + home + power.
Let it restart and so far after about 1mth+ did not encounter this issue any more.
Hope this help :fingers-crossed:

i have the same problem
all motions are off
and still have it random....only restart to close the sensor

Gyro sensor

I've tried using camera electronic level out of box, it's off by a degree. I've tried calibrating many times to adjust the gyro sensor.. And it's still off by a 1 degree even after going through the proper procedures. Anyone having the same problem?
Even when playing racing games, I have to hold the phone slightly slanted to drive straight..

Incorrect gyro sensor issue.
yes, the same thing i have noticed in my phone, i have tested several units and they all suffer the same gyro sensor issue.
I do not know if this is hardware problem or software issue, till now I have not heard any thing about fixing this problem.
it is strange that we both are only ones who noticed this issue!!!!

nope... mine too

I also experienced this problem with the G4. I believe it is being caused by the camera hump causing the phone not to sit perfectly level when the gyro calibration is performed. I put a piece of card under the bottom of the phone to compensate for the camera and make the phone sit flat, reran the calibration (from the settings > display menu) and this has fixed the issue for me.

OnePlus 3 loses much energy when it's inside my pocket

Hey people,
my OnePlus 3 loses much energy (up to 3 percent in 5 Minutes) if it’s inside my pocket (!) - especially then if I move at the same time.
I have already disabled the gesture functions - however, the problem remains.
Actually the problem can only be reproduced in my pockets
- latest Stock-ROM
- no root or other deep system changes
Any ideas how to narrow down this issue?
Best Regards,
Chris

dont use it as your pocket vibrator then...
have you checked the smart lock? it can keep your phone unlocked while you carry it.

Does it only happen when the screen / fingerprint scanner are against your body? Maybe they are detecting skin through your clothes and constantly trying to do something?

This. I think this is causing the issue. If you are slightly warm/damp/moist (someone reading hates that word ), it will try and scan your leg. My guess is perhaps it's not checking the ambient/proximity sensor to see if it's in the pocket or not.
I had this issue on the OnePlus 2 as well, although not as bad.

Thanks guys!
I'll try to wear the phone outward inside my pocket to see whether the problem still occurs.
Btw, i did some tests via "GSam Battery Monitor" and figured out the main-process which is producing the problem:
It's the "kernel". Does the kernel controls one of the mentioned sensors (ambient/proximity sensor) ?

Just be more wary of the screen being knocked/bumped!
Yeah that handles hardware as far as I know (might also be under other processes if they use it too though)

Alright, thanks for your quick feedback.
I guess i will reset my phone now...

I'm pretty sure it's the fingerprint sensor. Really sad to see that OP3 has this issue too, this started happening to me on OP2 too after the marshmallow update. They made the fingerprint scanner much more sensitive, greatly improving it's speed but this started happening. The workaround is to keep the phone in your pocket screen facing outwards...

I have the same problem. It should be fixable via system update to not activate the fingerprint sensor while the proximity sensor detects something.
Or am i missing something here?

Same issue here

Same issue. It's kind sad that OP can't handle this to prevent waking up using proximity sensor like it happens with duoble tap. I hope that they will release an update soon.

Is there anything in settings called "pocket mode"?? a friend has a THL phone that has pocket mode which stops the phone from doing anything when it detects its in a pocket

Nope, I've searched whole settings and there no option like 'pocket mode'.

same issue and the screen is showing the message "too many attempts. try again later" i can't use my smartwatch because the phone make a call or sent a message it self in my pocket.

I've created an e-mail to support with issue describe. Will update thread while getting reply.

Yes this is a bad bug which OP need to fix asap.

So what's the solution to the problem, finally?

We simply keep the phone face up in our pockets? That seems like a quick fix we shouldn't have to live with...

You would think that priority would be given to the proximity sensor. If triggered it would disable the finger print input.

OnePlus 3 (Soft Gold) Fingerprint Scanner Randomly Doesn't Register Finger

Out of random, usually when I take it out of my pocket, my OnePlus 3 (Soft Gold) doesn't register that my finger is touching the fingerprint scanner. It doesn't vibrate or anything. It's quite random and dont know why it's doing it. When it doesn't do it, it works perfectly fine. Fast as ever! Has anyone else experienced this issue with their OP3?

And I would say it does it only 5% of the time.

When the proximity sensor is triggered, opt goes into pocket mode which disables the fps. Check if you are covering the proximity sensor

Hi Connor,
i'm experiencing the same issue but it seems to be more like 20 percent of the time, depending on how long I keep it pressed there. Did you figure out what was wrong?
-Bob

The same exact things also happen with my OP3 A3000 Soft Gold, sometimes when I put it in the pocket for a long time (probably around 20-45 minutes), it doesn't instantly recognize my fingerprint anymore.
But it only happened on random occasions and not so often, so I don't' really mind it. My workaround for this is just pressing the power button to light up the screen and put my finger on the fingerprint scanner and it will be unlocked as usual.
BTW, I'm on OOS 4.0.2 and Franco R10 kernel.

Happens to me too, but rarely. When the phone is left untouched for a long time. I have the graphite one.

This can be due to the doze which deactivate the sensor and hence makes it slow or unresponsive

I too have the same model but it hasn't happened with me ever.
I would suggest you to record several fingerprints of the same finger...
But if the problem persists try factory reset:good:

Actually, I have the same issue. I guess I swipe my finger too quickly sometimes

no pocket mode - proximity sensor gets ignored

After being new to the pixel 2 xl I'm rather confused as to why there's no pocket mode or judge - I'm able to unlock my device while being in my pocket (fingerprint & dt2w), usually there's a option like "avoid accidental touches" or a inbuilt "pocket judge" that blocks all inputs when the proximity sensor detects anything close but this is not the case on the Pixel 2 XL (something that worked flawlessly on all my OnePlus devices) - after reading the plenty reports of people with proximity sensor issues I did check my sensor and it detects proximity just as it should, it just seems not to block inputs... Or is it intended from Google that the proximity sensor gets ignored? Due to the many reports of people that claim their proximity sensors always detect anything near, hence the screen stays black when call is finished...
I feel like it's really inconvenient to have a device in my pocket that doesn't lock itself when being in a pocket, under a pillow or something like that and rather completely ignores proximity even though it's readings are correct - any thoughts on this? Did I miss something?

Must be something wrong with Your device, because when I cover my proximity sensor display goes dark and it doesn't accept touch to wake.

Thanks for the fast reply this gives me hope to be actually easy to fix, I'll check another kernel next, however I'd be surprised if it's related to @flar2's ElementalX...

same

ive had the same issue only on stock rom. When on stock I used Gravity Screen. Currently on Havoc and that has an option to block screen when proximity is covered.

The weird thing is AndroSensor reports proximity as working just fine, also on calls it's working - when I hold the screen to my ear it blacks out and gets back on when I remove it, I get the impression that Google has not implemented at "pocket mode", I also compared it to N5X running stock 8.1, same behavior, even though it's just the fingerprint due to the lack of dt2w, which unlocks the device even in the pocket...
On the previous devices I owned (OnePlus 2, 3t, 5t) dt2w & fingerprint was blocked as soon as proximity sensor detects anything close, I was expecting this exact behavior to be Standard, it seems however not to be the case unfortunately!
Sent from my Pixel 2 XL using XDA Labs

A workaround/suggestion...
I had a really bad issue like this back on my Samsung Galaxy S5 (there was a well known bug), and what I ended up using that worked really well was an app called Gravity Screen by Plexnor (https://play.google.com/store/apps/details?id=com.plexnor.gravityscreenofffree&hl=en); granted it's been a LOOOONG while since I've used and even seen the app, so I can't say if it actually works on the Pixel 2 XL and/or Android 9 Pie, but if it does work as intended, it may just give you a (at least temporary) solution...
