Stop phone from turning on when rotated on side during phone call?

My GF and I are very annoyed at this problem. When you tilt the phone on it's side, lik eholding it with your shoulder the phone will turn on. It just so happens that your phone's mute button will be on your cheek and we mute each other.
Is there anyway to stop this? Thank you guys in advance.

Are u sure u are not "uncovering" the light proximity sensor when u tilt it. Its very sensitive, and I have noticed it get turned on when the phone gets an inch or more away from ear exposing the light sensor to any form of light.

While on the phone with my girlfriend at night this happens a lot. Because it is so dark, any movement I do will cause the screen to turn on and I have to hit the button to turn it off.
Just try vto keep it glued to your face :/

Yeah I'm sure. The feature is suppose to be for when you set the phone on your desktop the screen will turn on so you can hit speaker or end the call.

Umm simple work around, get something opaque and stick it over the light sensor with something that won't leave a residue so you can take it off when your call is over?

obviously some people fail to understand how this works. there is a light sensor for screen brightness and a proximity sensor. it is the proximity sensor that detects your face and turns off the screen. the light sensor is not involved in this process. what is happening is that the i9000 roms have default android 2.2 settings that force the proximity sensor to be ignored in certain orientations, i dont know about the new att updates but the 2.1 roms had the overrided from samsung. i tried to fix it in tasker but tasker lacks the option to power off the screen, it can go to lock screen instead which may be acceptable for some. there may be a different way to do this in tasker but i need to experiment more.
there is no external workaround for this as it is not the proximity sensor being uncovered that causes most problems but the phones orientation. any workaround or fix must be done with software or a change in a file somewhere.

I am sorry, and have been humbled •_•

This is correct. In simple terms the orientation sensor takes presidence over the proximity sensor. So if you turn the phone on its back while on the phone, the screen will turn on.
There are no fixes for it that I'm aware of.

How abt keeping auto-rotation off all the time, and turning it on only when needed, as a work around?

It's not linked to auto-rotation unfortunately, Its just something that we have to live with.

Man... wish there could be one but sounds like there can't be.

[Q] Screen stays off during call no matter what I do!

When I am in a call, putting the phone to my face turns the screen off using the proximity sensor. However, removing the phone from my face does not turn the screen back on. Nothing turns it back on even if I push all the buttons or hold them or do anything unless the other person hangs up. I cannot remember when it started....before or after the recent update.....but it did start very recently. Any ideas? If I turn off the proximity sensor during calls it works fine by locking and unlocking the screen with the buttons.

Is anything covering the front facing camera, or light sensor? Like a case, bad screen protector, etc....
Does your front facing camera work just fine as a camera?
How about air gestures? Do they work?
I'm asking these things because it seems your proximity sensors aren't working properly. Your phone thinks it's next to your head all the time, so it's not waking the screen until the other person ends call. We need to find out which one is acting up and why.

The front camera works, but in my office it seems VERY sensitive to light. The lights are glaring heavily. I never use the front camera so I don't know if that's normally how it was. Air gestures work when the screen is on (swiping left and right to view my photos), but the quick glance won't work when the phone is locked. The weird thing is that quick glance works when I do the "try it" tutorial only.

Ok now it seems quick glance DOES work when the phone is off....I just couldn't do it correctly.
Main problem still exists though.

I was thinking that, but I'm tempted on resetting my phone and seeing if that helps. The problem is that I would lose all my app data and I'd hate to deal with that.

Unfortunately this sounds like a bad proximity sensor. This can be verified by testing the sensor by dialing *#0*#
I had this happen to my last Note 3. The only difference was I could turn the screen back on with the home button.

I tried that *#0*# test and I can activate the proximity sensor, but it seems to stay on after that.

This is a known issue with our phone. I had this issue myself. Plenty of times. Just call ATT and ask for a replacement.

Yeah I just found this:

i stumbled upon this thread and took my phone apart and sure enough there was lint in it. in the dial pad using the *#0*# method, when i covered the sensor the screen would light green, vibrate, and stay that way after i moved my hand away. i cleaned it and everything is perfect!!!

Am I holding it wrong? How should the proximity sensor and Ambient display work?

I just got the phone last week and it’s always had a screen protector on it. I know many have issues with the proximity sensor covered but I don’t get how the phone should work. All my other phones turn off the display as you put the phone to your ear and on again if you move it away to look at something or end the call. The Nexus 6 just stays on until the screen time out and then I have to tap the power button to get the screen back.
I installed a proximity sensor app (Proximity Sensor Finder) and it seems to work fine though I don’t know what the readings would be without the screen protector covering it. It shows 5.000305cm until my hand gets within two inches or so and it jumps to 0. The app says some sensors are discrete so seems ok and the readings are very consistent and fast. So why is the screen not turning off?
Also, the Ambient display setting says it will turn on the display when you pick up the phone or get notifications. Never worked. ???
Bad phone, software or setting?
Thanks.
P.S. Why in God’s name are the volume buttons and to a lesser extent, the power button, dead center of the phone? I hit them every flipping time I pick it up. Is there a way to disable the volume buttons when the screen is off?

my suggestion would be to take your screen protector off. when you pull away from thd phone, the screen should pop on, but it not doung that for you. over the past 8 months or so, ive been reading about this same issue. and its always fixed by raking off the screen protector. im fuessing that your screen protector is covering one of your sensors.

Understood but:
"I installed a proximity sensor app (Proximity Sensor Finder) and it seems to work fine though I don’t know what the readings would be without the screen protector covering it.

Can someone without a screen protector on chime in with naked sensor readings?

your phone has its own proximity sensor thats being blocked by your screen protector, probably. im telling you that of the very many that have been reporting thus issue, have no more issue when they remove the screen protector. its worth a try, isnt it?

for most ppl it stays off, a few that ive read stay on non stop.
for example.. if it doesnt "see" your face get close, it wont turn off the screen.

Yea, but the protector would not be usable afterwards and it was really hard to get it on clean and lined up and the sensor readings are the same. I thought the folks that had problems had stuck or sporadic readings.

Mine can be toggled on and off with the power button, never gets stuck. It just acts like the proximity sensor mode during a call never activates. It only powers off after the normal screen timeout if you are still on the phone. The sensor does see me and sets the value the zero.

It’s on, even tried toggling it.
The buttons should be higher. I understand you can’t reach the power button on larger phones if on top of the phone but putting the volume at the center of gravity is crazy. It’s actually noticeably difficult to hold the phone without it dipping when grabbing it lower and that’s after training myself to grab it lower. I still forget and grab it in the middle like any brick sized object. I'm old, hands weak.

I have read here, somewhere, that the proximity sensor does not have a variable output. It's either off or on, so to speak.

Probably yes but everyone who had a screen protector without a sensor cut out had to change it for one with a sensor cut out.
This is step 1. Even if this isn't the cause, it will cause problems later.
You say not variable. Sure on or off. That said, a protector can limit how close the "close" reference can be identified at.
Step 2 is a factory reset.
Unfortunately, can't troubleshooting without doing these steps.

That is my understanding also and someone posted above that they have the same readings from the sensor without a screen protector. They did not say but I’m assuming their phone works as it should when on a call. Again: "I installed a proximity sensor app (Proximity Sensor Finder) and it seems to work fine though I don’t know what the readings would be without the screen protector covering it.

I know, I know. I’ve read that many have had issues with screen protectors but I thought the folks that checked saw that the proximity sensor readings were also bad. Mine seem to be just what the phone would want to see.
I will take it off at some point and I guess I’ll be the first to verify that even if you use an app to monitor the proximity sensor readings and they look normal the protector can still cause an issue or it is something else.

I did find that the Ambient display will not work without screen lock turned on.

True, because it needs a lock screen to display it.

The screen worked as it should randomly the other day. Only on the one call. I pulled the phone away to look at something and it turned the screen on. Put it to my ear and what do you know, it turned the screen off. Not worked again so far and I ran the sensor app right after the call and it showed just what it always has, zero. Anything close to the phone you get a zero every time, right away. The phone app just ignores the zero reading.

Screen goes black when on call (speakerphone). How do I disable this?

I multitask all the time on my Note 9. However when I try to use the screen when I'm talking on the speakerphone (for example, look up a phone number or web browser) the screen turns black immediately when my hand covers the proximity sensor. This is especially an issue since I hold my phone in landscape almost all the time (my left hand covers the proximity sensor). I'm baffled why Samsung would want the proximity sensor to turn off the screen when talking on the speakerphone... with no intuitive way to disable this.
Seems kind of odd considering this phone is meant for busy people who multitask. I've already spent a lot of time looking for a solution for this... but, haven't found a solution yet. I've already tried "Kinscreen" and "Keep screen on" on Google play. However, it doesnt work on the Note 9.
So... what's the trick to disable the proximity sensor on the Note 9?
Saw the below article by searching on Google... However, it seems to be a bogus website with false information:
https://gettechmedia.com/how-to-turn-proximity-sensor-on-off-samsung-galaxy-note-9/
PS: I have a Verizon phone.. so I can't root it either.

Sounds like a screen protector or similar may be causing an issue with the proximity sensor

The screen isn't supposed to turn off when on speakerphone, mine doesn't

Thanks for the reply. I probably should have mentioned that the proximity sensor works correctly. If I move my finger over the sensor, it blacks out the screen. If my don't cover the sensor, the screen turns on immediately.
I think that's how the proximity sensor is supposed to work by design. This functionality is in place so that when you move your ear to the phone, it turns the screen off.
The problem I have is this that the proximity sensor turns off the screen if I accidentally move my finger over the sensor; even when I'm talking on the speakerphone (when my phone is not near my head). On older versions of android, there's a simple setting to turn this functionality off under Phone/Call Settings.

Could you please check to see what happens if you move your finger over the actual proximity sensor when the speakerphone is on?

Thanks for confirming this! So... my next question is how do I fix this issue. I wonder if there was some setting that I changed that causes this behavior.
PS: If I enable "Smart Stay", the screen will stay on (even if my move my finger over it), as long as I'm staring right at the screen and hold it the phone vertically.

I'm almost too embarranssed to say what the real problem was. I guess I'm more tired than I realized. I just noticed I didn't actually have speakerphone turned on. I guess the phone speaker is so loud that I thought the speakerphone was enabled! Thanks for trying to answer my question anyway.

Lol, glad you sobered up ??

Verizon N9. Screen goes black when on speakerphone after 10 seconds.
No screen protector. No proximity sensor issues. This is after I hit the speakerphone button (unlike OP that didnt know speakerphone wasn't truly engaged)
How do you get the screen to stay on when using speakerphone?
Again - this is NOT a prox sensor issue. The prox sensor works great when I am using it against my ear/face and not using speakerphone.

Same issue with the s10+, screen goes off after some time on speakerphone same as note 9.

Always on display always on

Hey i noticed that AOD is always on, like always for real even in pocket the simple thing to test that is just to cover the top sensor so it should switch off.
Am i the only one experiencing that ?

Sounds like it is doing Always On correctly to me...

IT should get off when proximity sensor is covered
