Front sensors waking phone? - Sprint Galaxy Note 4 Q&A, Help & Troubleshooting

So i use the fingerprint unlock and recently ive noticed my phone has been getting hot and dying quickly. I think i found the issue and i dont know if this is a settings issue or it supposed to be like this. After i lock my phone if anything comes close to the sensors to the left of the front facing camera it wakes my phone. So even in my pocket i will pull it out and the screen is on already. Is there a way to stop this? Is it a defect?

Difficult to turn on screen in dark

Has anyone else noticed that when in a dark area, pressing the main button will turn on the screen but it will then automatically and immidiately turn off?
Several times I've gotten into a battle with the phone only to lose, turning it on and it turns off, then turning it on again and so on...
To compound the issue, in these situations it seems that double tap is signifigantly less responsive to activate the screen as well.
I'm pretty sure this phone is using some sort of facial recognition, it has smart stay doesnt it? I think it has gravity/accelerometer to turn on the screen when you pull it out of your pocket. In the back of my mind I'm thinking that since it cant see me it is shutting off but this doesnt seem consistent...
I'm running stock rom, rooted with twrp. Any ideas?
I have not experienced that. Did your G3 do that out of the box?

Never heard of it. Screen is set to auto off in 30 seconds. Change it to 2 min and you should be good. If u running without a case then maybe the hand is touching the edges of screen this will also shut screen off in double tap.
BAD ASS G3

I didn't notice it until the last week or so. but I kind of feel like that was because I hadn't used the phone that much up until then. I didn't make any major changes to the phone immediately before I started noticing it either, I had already had it rooted for about a week. I feel like the stock rom does have some glitches to it.
The G3 does have a "smart screen" feature that detects your face (Settings > Display). Disable that and see if it helps.
I've not run into this in the dark but have when I try and use my arm band holder when running. The holder covers the ambient light sensor so the phone thinks it was accidentally turned on like in a pocket and shuts right off. Super annoying.
Noticed similar behavior when the phone is in my bike mount at night. Basically it's acting like the proximity sensor is covered. In my bike mount's case, it is covered by a clear screen cover, but normally that doesn't trigger the proximity sensor. But when it's very dark out (not under a street light etc.), it seems to think it's blocked and turns itself off. Annoying.

Ive had this issue too investigating now
Had that issue when I was using the lock screen face unlock. In the dark it didn't see my face and then it shut off. Setting is in lock screen section

Lol.
I have the same issue EVERY night. Why is that? It's very annoying
Same issue here
it seemed to resolve itself when I factory reset my phone
but after I got my apps reinstalled from my google backup it started again
so it seems like it's a software issue - not sure to which app it is related to
let me know if you find a fix - this is quite annoying
Me too. I've been facing this issue at night, when it's very dark.
Me and my buddy were in the car during a roadtrip and it was very dark, I mean like: No lights outside, no lights inside the car, the double tap feature didn't even work to begin with and whenever I tried to use the "Power Button" It would come on and then suddenly 'boom' Turn off, now this would happen a few times until it stays on. Weird...
I just experienced this myself, first time I've seen it happen in the 30 + G5's that I've sold. If it's in the dark it just doesn't turn on at all. I hope LG is fixing this. I'm about to Factory Reset it right now and hope for the best! Someone else mentioned that this is the only forum that is disccusing this issue. It must be a very few that are effected. I'm testing another one as we speak.
Has this issue been resolved? My friend's G3 also has this issue. Day time no problem. When it is dark the screen wont' stay on.
Same problem, no fix yet
Same problem here - Pointing it at any light and pressing the power button will turn it on. (As will plugging it into power). Tried tinkering with all sorts of settings (face recognition/auto dimming feature/etc) nothing worked. Tried factory reset, that didn't work either.
My issue started after i had my screen replaced (by a shady shop) who probably didn't do a good job of packing it back together....I'm going to see if I can have someone open it up and clean it out a bit..
I have the same issue on my G3. Even if you're under the covers in bed, the thing doesn't turn on until it gets light. It basically doesn't turn on in the dark through double tap and actually not even with the power button. It could become a safety hazard for someone in an emergency situation.

Ghost touches in pocket? [Proximity sensor issue]

Anyone think that perhaps the proximity sensor of this device doesn't work always?
After using my phone if I put it in my pocket without locking I expect that it will not register ghost/accidental touches but I don't think the phone handles that very well. Often when I pull out the phone I can see some random screen got opened.
Are others also facing this issue?

Not random screen opening but once i remove it out of my pocket i get a warning screen saying accidental touch protection is on or something.
Or sometimes a clock, the one on the lock screen where you just tap on it and it zooms in the clock.
Have you turned ON the Accidental Touch Protection? I initially had Ghost Touch problems during jogging but with the change of placement of the phone, i now dont have the problem. Make sure that the screen faces the pocket side not the thigh side. Most of the ghost touches happen while interaction with the thigh.

The setting was already on. Anyway I toggled it off and on again just in case. Making the phone face outwards in the pocket may work as a suggestion, but it still probably implies that the phone is not doing a good job in blocking these accidental touches. I also like the screen inwards in case I hit a table edge or something.
The other setting I did is to ensure the phone locks itself quickly after the screen goes off. Earlier I had it at a higher value and its possible the device was switching on to an unlocked state. This is working a little but in my old devices I recall I was able to pocket even if the screen was on and i didn't really have this issue.
Accidental Touch option don't working well as need it.
Sometimes working and sometimes don't but proximity sensor working like a charm
Think it's a software bug.
Working like on a wind

Is anyone facing an issue with the proximity sensor in OnePlus7T

Ever since I've bought OnePlus 7T, the proximity sensor is giving me a lot of problems. Sometimes the screen lights up while I'm speaking on the phone and the speaker is activated. Sometimes the call gets recorded. Sometimes if the phone is in my pocket and I try to unlock it, it says too many attempts.
Yes it very annoying, when removing it from pocket accidently my fingerprint matches and something something happens.

This is the biggest reason I may be going Pixel 4...
Yes I too have this issue with my OP7T
Yup, same issue here.
Another thread about it here - https://forums.oneplus.com/threads/proximity-sensor-doesnt-work.1147600/
Also issue present on OP7Pro forums.
Seems to be related to this "Virtual Sensor":
https://www.ellipticlabs.com/2019/0...eaner-design-to-oneplus-7-series-smartphones/
So we have to wait and hope (could be this same as Never Settle? :d) that can be fixed with a software update.
It seems to get worse the more I use my phone. Anyone else notice this? Brand New it never did it

Someone on the OP7T forum suggested it may be Tap the Screen to Show (let's call it TSS) feature.
I enabled DTW. This will trigger Ambient Display -> "Tap the Screen to Show" to be disabled.
Tried and the screen still won't turn off when on a call with the phone on my ear.
Both options disabled (no DTW and no TSS), still won't turn off.
What did work though, was to turn off screen once with the power button:
- I was in a call and the screen was on,
- turned off the screen using power button,
- I took the phone off my ear -> Screen on
- put the phone back on my ear -> Screen off
Maybe someone can make more sense of it.

I tried the above also same thing. I am tired of this BS. I am constantly pressing hold or dialing with my face unless I have the phone shoved in my ear. I almost didn't buy the 7t cause of this issue coming from the 6t with the same issue

Yeah, I am starting to remember good ol' days with the OPX. Every OTA was fixing one thing and breaking 3 other.
At that time I said no OP again, but still, this one seems to be be a good phone. Time will tell.
Coming back to our issue, I am puzzled that only a few people reported this.
Are you guys are on stock kernel or something custom?
I don't think I have this issue, but the sensor seems to function a bit differently from what I'm used to. When the phone is horizontal, covering the sensor does not turn off the display. But now do the motion of raising the phone to one's ear, and the display turns off. Just an observation, yet to experiment properly.
Does anyone know where the sensors are located on this phone? Is there a picture on the internet that points out the different sensors?
Edit: Yep. This one has a virtual sensor. It works differently.

Not rooted, but using a custom dialer as the default Phone app (True Phone).
When I switched the default Phone app to Oneplus App, I could not reproduce the issue.
Testing for a few days to see if this works. Would be such a pity if the app is the problem because I really like it.
Also I just sent a log to OP support (they contacted me after I logged the issue on the feedback).
Yes, it is using the virtual sensor as you said (link in my previous post).
How does the virtual sensor work?
Sent from my [device_name] using XDA-Developers Legacy app
I couldn't find anything concrete on how this software-based proximity sensor, Elliptic Labs INNER BEAUTY, works. The keywords are: ultrasound, sensor fusion, and machine learning. A hardware-software I guess.
The 7T does have an IR sensor under the display, but I think this is only used for DT2W and Tap to Show to prevent the display from accidentally turning on when the phone is in the pocket and so on. Not for calls.
Fully Unmodified phone - same issue here. Phone regularly turns on airplane mode while I’m on a call cause it is registering face touches. Screen regularly flickers while on calls as if rapidly moving away from my face....
This was not a problem on my 3t a while ago and the issue is driving me to switch phones alongside some software instability (random lag and keyboard jitter) (animation issues after launcher swap) (soft-lock on navbar or gestures but not a play store replacement)I usually fix by rom swapping on one plus phones andddddd twrp is dead (for now) and no ones working on a valid replacement.
Will be keeping this phone in hopes of twrp eventual return, but need that stability

Twrp is out for the 7t. It's not flashable last I checked but it is bootable and usable for what I used it for which was a backup of stock rom

Question Issues with proximity sensor and pocket mode with my OP9 Pro

Hello to everyone,
I bought my OP9 pro 2 month ago, and I loved it since first day, but there are some bugs that I really hate!!
When I finish a call or when I finish to hear a voice message on Whatsapp, the brightness goes down, without I touch anything!
In last days I find another annoying bug, sometimes when i put off the phone from the pocket, the pocket mode remain activated, also if I turn my OP, also if I unlock the smartphone... These two bugs are getting me crazy!
Can anyone help me or I have just wait some software update from OnePlus?

I've exactly same bugs on my OP 9 Pro , sometimes brightness goes down by itself and without touching it, i've always automatic brightness switched off! Then taking it out from Pocket with Pocvket Mode switched off, i find apk opened by themselves, so a total mess!

Yes! The same for me! I'm rally freaking out! And Oneplus doesn't care about these bugs!
I had the same problems, but interestingly I face it only when my Camera and Mic is turned off.
for me it was dirt an pocket lent, the sensor is very sensitive for some reason so when ever i get that problem I wipe it and it works flawlessly for the next few days until it needs to be done again
Same here, sometimes I can't even turn on the screen after a call...

Hello. There is a solution to the problem with the proximity sensor. You go to the dialer enter *#808#, looking for "Device dubbing* and there are "proximity sensor test", tap and choose "infrared proximity calibration". You calibrate the sensor. it should help you. You can also calibrate other problem sensors. Try it with a brightness sensor too

Question Proximity sensor failure

Currently running Pixel Experience Plus android 11. Others dont report the same problem.
Would this be ROM based, firmware based, vendor based, or what else ??
Its a major annoyance as the tap to wake, face unlock, and position of the fingerprint reader all mean this wakes in pocket constantly.
Tried hard resets etc but stumped.

The reality is there is no proximity sensor present in mi 11x
and in miui the call screen becomes black as miui using accelerometer and some kind of hack to do that.

So this constant pocket activation is a feature ??
I cant believe everyone is just living with this ??
Unfortunately it is so and this explains why even if the phone is away from the ear but placed vertically the screen turns black.

Is that only with MIUI ??
So what combination of settings are people using to minimize this ??
I haven't had a phone without a proximity sensor in years, I didnt even think one would be sold that way.. Its unusable like this, constantly waking in pockets, error input and attempted unocks etc
Testing it (pixel experience plus) my phone never senses, in any orientation.. Others report some form of sensing.
Upright.. hand to phone.. hand over phone.. I am not getting anything.
It wakes on movement.. It wakes to attempt face unlock (I guess).. It wakes on screen touch,, it never overrides that despite there being an option to prevent accidental wake up (which has no noticeable effect). I dont see what combo of settings may be correct here.
Its currently flat out unusable.. Its a mobile phone which you cannot put in your pocket and which wakes as you carry it. People cant be just accepting this...
The Truth is truth that this phone doesn't have proximity sensor

thats now shockingly understood..
But other people report some kind of gyro / light sensor / accelerometer / etc combination thats providing some useability. Useability I dont have (Pixel experience plus 11).
The config I have so far.. Is not doing anything.. and is basically non viable..
You cant put it in your pocket !!! What kind of mobile phone cant be put in a pocket or carried..

I don't get what your problem is, plz describe it better. You say that you have problem with proximity sensor, but then you go on to say that your phone unlocks in your pocket for no reason and I see no connection between these two statements. Proximity sensor works only during calls, it has nothing to do with preventing unlocking tge smartphone in your pocket. Are you sure that you're not accidentally putting your finger on the fingerprint reader when you put it in the pocket? If you want, you can make the fingerprint reader read your fingerprint only after you press the power button, mere touching will not unlock it. But you have to change it in settings in MIUI, I am not sure how it works on your Custom ROM.
I have no problems you describe on my Poco F3 unit. If reverting to stock MIUI doesn't work, consider sending it for a warranty repair.
