[Q] HELP! Always Active Front Camera! - Galaxy Note II Q&A, Help & Troubleshooting

Hi, I have a very weird problem with my N7100. When I put my finger or anything in front of my front camera, the toggle bar will disappear and the screen will be still and no response. This is really bothering especially when I am playing games. Cause I swipe my finger in front of my front camera unpurposely and the game will be interrupted. It looks like the front camera is active to detect anything in front it, and if there is any thing blocking front camera, the screen will be frozen up!
This problem start with my official system (Samsung Touchwiz) comes with N7100. So I rooted my phone and put alliencerom there, it comes back again....If you restart the system, it goes away for a while and will come back sometime. Really bothering, I have found out what is the trigger, I believe there is a trigger though.
So I don't know any N7100 user encountered the same problem? And any idea about getting rid of it?
Thanks so much!

Are Smart Stay/Smart Rotate and all the motion stuff turned off? If not try turning them off.

I checked all those and they are off, I actually never turned them on. Today I found that after I use groove ip make a phone call. The problem will come up. I don't know exactly how.....
I test it a little and I found it is the function of Groove IP which freeze the screen when you are making a call. But somehow after you done with your call, the front camera just keeps doing so. I think there is something with screen rotation during the call.
Now I think problem solved by checking off "auto rotate" in Groove ip setting.
Thanks, XDAer.

[Q] Phone Call Proximity Sensor

Noticed recently that When a phone call is in progress, the screen will go black no matter what and to get it to come back i have to manual hit the top power button.
I first noticed it with energy rom. When autobacklight was enabled, their was no getting back to screen at all. Disabling autobacklight at least allowed me to get the screen back after clicking the power button.
I switched to core cell rom and noticed the same issue, however, i can manually turn the screen on again even if autobacklight is enabled.
I have no further problems with the proximity sensor, just this one.
Is their perhaps some sort of proximity app that i could use to diagnose whether this is a hardware problem or software problem?
Ok, I had a similar issue, where the phone screen would turn off as soon as the "send" button was pressed, and the only way to turn it back on was either hanging up, or waiting till it felt like coming back on.
My proximity sensor was stuck "on". I could see the sensor status in the registry (don't remember offhand the reg entry, but it's a live reading of the sensor, 1 or 0). I installed "Proximity Sensor for Screen Off v0.2" from http://forum.xda-developers.com/showthread.php?t=624206
That was a mistake on my part, though... then the screen wouldn't come back on! It took some real finagling to get the screen on.
To fix it (temporary? permanent? dunno...) I waved a small neodymium magnet over the sensor (near the ear speaker). I have no clue why that worked. I don't know why it stopped. I *definitely* don't know if that's the issue you are having. But it's worth a shot
I've never had this issue after many different iterations of the Energy ROM.
Do you run Task29 when you flash ROMs?
Yeah i always task29. I don't believe it is the rom since i have tried another rom and the problem persisted. I tried the magnet idea but it didn't work. It was a refrigerator magnet though so i didn't expect it to. Anything else that requires the prox. sensor to work, has no problems and that is why this is weird to me.

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.

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.

Screen rotation lag

Has anyone else had a screen rotation issue on their Note 4?
In almost all apps, rotating from portrait to landscape or landscape to portrait has a very long delay. Usually at least 10 seconds, and sometimes not at all unless I tap the phone on a hard surface, and then it rotates.
That might suggest a sensor problem, except for 2 things that do work:
1) In camera mode, the buttons rotate instantly when I rotate the phone
2) In GPS status, which indicates phone orientation, it registers the screen rotation as roll in the pitch/roll display, although the GPS status screen does not rotate correctly either.
These seem to confirm that the actual sensor is working ok.
I've tried safe mode, clearing cache, closing all open apps. Nothing changes in the behavior. I also tried turning off SmartStay, and changing display mode.
Some hits I found suggested turning off "smart screen rotation" on the S5, but that setting doesn't seem to exist on the Note 4.
Has anyone had this problem and found a solution?

This is like a dead giveaway for a hardware problem.
Wow, 10 seconds is a looooonnnggg time for a screen rotation. I've never experienced this on my Note 4, so the only thing I can think of is talking to your carrier or Samsung themselves to ask about it. Sounds like a hardware failure to me.
Yeah, that does make it seem like a hardware problem. But like I said, the camera buttons rotate instantly every single time, with zero lag. That would seem to say the hardware is working, unless the camera uses a different sensor for rotation than the rest of the UI.
Also, my wife has the same issue with her Note 4. We got them at the same time, so maybe it's a problem with that batch.
Since we both have it, it seemed like it could be caused by some app we both have, but I thought booting in Safe Mode would eliminate that, as only stock apps run in Safe Mode.
I guess I could wipe the device completely and see if it resolves. If not, I'll take it in as a hardware problem.
After a full wipe and cache clear, it still has the same problem. I called Verizon, and they are shipping out a replacement phone.

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.

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

Proximity sensor issue

After a few days of using this device i noticed that my screen turns on during phone calls. After doing some research it came out that the proximity sensor is not working properly when phone is being tilted to horizontal position with screen upwards. It just immediately shows that it is far away from any object even that it isn't. The fun fact is that when covering the sensor with my hand while phone is laying on his back doesnt switch it and rotating the phone to vertical position also does not make any effect like the sensor would be locked. Covering it again in that position makes it work.
Can anybody help me with this issue? It's very annoying for me and makes my phone unusable for making calls.
Edit: similar problem here https://forum.xda-developers.com/android/help/huawei-nova-5t-proximity-sensor-problem-t4136595
Same problem here...
here also
I am so lost. What do I do with the phone? What? When does it happen? (Also subscribing.)
Same here, and i notice i have also problems with whastapp and telegram audio notes.
Sometimes screen goes blank randomly and with no reason when i'm listening a audio note.
Hi. Its a well known problem. Its becouse the device has a ultrasonic sensor not like any other. Sensor like you already find out works only in vertical position of the phone. Its well described in the net how it works. Just search. In 4PDA in the section for our phone. But you need to know russian.
I found that thread and it seems that not everyone notices that... Not spending more time on reading this I found a workaround on my own: an app that keeps the screen disabled after first switching proximity sensor. Then you just need to use the power button if you want to use the phone.
Same problem here, it's very frustrating. I can turn the screen back off during a call once I see it's turned on by itself, but it keeps turning back on. I'm sick of muting calls and hanging up on people by pressing buttons when I'm on the phone.
What is the app that you are using @Spectre45?

Listen. There is no proximity sensor at all. The upper mic, speaker and the sensor for orientation are doing the job. When you pick a call the speaker is sending ultrasonic signal and if it locate your ear it dims the screen. Once it works it is working in all positions. But if you move your phone away only in horisontal position it will nit work untill you mive it in vertical again.
Edit: Experienced this issue too. Annoying.
Does using Xiaomi.EU fix this problem? This issue really gets on my nerves. I started daily driving this device (finally I was able to unlock) and I just cannot use it for calls, which is kinda ridiculous from a phone.
Flashing Xiaomi.EU fixed the issue and calls now work totally fine.
I believe it's Google Dialer making all the trouble, so basically EEA default rom will always be troublesome until Xiaomi decides to fix it. This is only a theory however. All I know is that the Xiaomi.EU rom saved my phone.
I was using the phone with cover provided by MI, upon removing that back cover I encounter no such issues.

I didn't have any proximity issues on stock with google dialer. It's not google dialer, it's how you position your head against the earpiece. Sensor is ultrasonic, so it probably doesn't detect properly depending on the position people hold their phones in...
I have the same problem with my work phone - redmi note 9. Tried the app "proximity screen off" but MIUI keeps killing it no matter what i do to keep it alive. It seems that sensor is located on front top right side of the phone so sometimes it gets behind your ear if you are right handed (mine are pretty small) and then the muting starts. When using the phone with left hand - no problems at all.
I would love to have a working app to keep screen off during call.
