Tab S LTE screen turns off during phone calls - Galaxy Tab S Q&A, Help & Troubleshooting

Even though my screen timeout is 5 mimnutes, during a phone call the screen dims at 10 seconds and switches off at 30 seconds. There are no settings I can see to stop it from doing that.
One setting which works indirectly is "screen stays on while you are looking at it" - it sort of works but is a global setting that also affects other things.
The tablet does not have a proximity sensor. Maybe Android is reading 0 for the proximity sensor and thinks that the phone is in your ear?
Any ideas hwo to fix this?

10.5 or 8.4 inch? I have the 8.4 inch and it most def. has a proximity sensor

10.5". It does not appear to have a proximity sensor, only a light sensor.
Then again the fact that the phone app puts the screen to sleep after 30 seconds is probably not related at all to the proximity sensor.

Proximity Sensor during Calls

Howdy Campers!
Quick question about the proximity sensor and in call screen off. When i have this feature checked "Turn off screenduring calls" should the proximity sensor be active and turn the screen on and off if i have it up to my head??This is what the feature reports to do.
When checked the screen goes off and will not come back on (none of the buttons seem to wake the screen, only end of call will).
Any ideas??
thanks!

Do you have a screen protector on or maybe accidentally covering the proximity sensor? The phone is supposed to wake when the proximity sensor isn't covered, not when the call is ended.

No screen protector or case
actually it looks like the proximity sensor isnt working well for anything....
besides the calls the air gestures (scrolling) stopped working.
I dont think smart stay works either....
i factory reset the phone still nothing
on the lock screen i do see the little white dot follow my hand around so not sure what to think.
any suggestions before i take this back to the store for a replacement?

AOD Not Turning Off In Pocket / Overturned - Can You Test

So I've noticed my AOD isn't turning off at all. While I do have it set to "Show Always", it should still turn off after a short time if the proximity sensor is covered., as was the case with the S7, S8 and S9.
Could you guys please confirm if this is the case for your AOD too? Turning the phone face down or put it in your pocket (or just cover the top half of the display) for a few minutes, see if the AOD turns off. Let me know if anyone sees it turn itself off.
You have to have AOD set to "Show Always" for this test to be valid.
I suspect this could be a bug which Samsung might need to be made aware of, hence my request for others to test. Unless I'm missing something VERY obvious. Or Maybe this is by design?
Thanks :good:
EDIT: thinking about this further, I reckon the proximity sensor is only active while it's flashing, such as when a call is being made. Because it's a "behind the display" type sensor. So maybe they made a trade off with AOD?
It's a sad news for you. S10+ doesn't have a proximity sensor as a trade-off for the screen (sounds ridiculous?). And some features are like sh*t due to the lack of proximity sensor. I don't know if I can go through with this so-called flagship

Ummm, of course it has a proximity sensor.....
Try making a call to someone (use voicemail if you want). You'll see a little white flashing dot to the left of the cameras, near the battery icon. This is the proximity sensor: https://hothardware.com/news/blinking-white-pixel-samsung-galaxy-s10-feature-not-bug
Try covering it up while in a call. The display will go off. Because you just covered up the proximity sensor. Because they do have one.

No it's not. Can you check it on your phone with *#0*# in the dialer or any proximity checking app? The result is always 0.
I had troubles with the double tap to wake and the show fingerprint features, and sometimes with calls when my phone behaves abnormally. Then I checked and it turns out that S10 doesn't have a proximity sensor. Samsung did other things to replace the proximity sensor's function, but it has been much worse than before

tried it on a S10E, the AOD always stay on even when in pocket.
Can confirm on my s10+. AOD does not turn off in my pocket or laying face down.
did anyone notice the werid little flashing spot above the the signal bars? that`s the only place where when I put my finger over it the screen goes off during call

Seriously, it has both a proximity sensor and light sensor as per normal. They may work slightly different, hence why crappy test apps from the Play store don't work. And why AOD is no longer turning off in pockets.
Watch JerryRigEverything's teardown, specifically here, where he physically points them out: https://youtu.be/kHzmFPoZbCA?t=427

Not only apps in Store, but the SS diagnostic mode doesn't show either. Check the attached pics of S10+ and Note 5 in SS stock diagnostic mode

Same here.
Tbh it's not really a trade off I'm happy with because it makes AOD a source of battery drain at this point. I want to be able to put my phone face down to save battery. Do you think this might actually be a bug?
Started a thread in the Samsung community forum. Maybe some of you guys can top up with your own findings.

Found this article which confirms the existence of a proximity sensor.
https://hothardware.com/news/blinking-white-pixel-samsung-galaxy-s10-feature-not-bug
The trade-off might be due to the fact that's the sensor is tied to that blinking pixel and is only active while making phone calls.

Same here, AOD doesn't turn off when flipping it over or covering top portion of the screen.
I'm starting to think this is why they added the feature of AOD only turning on when you tap the screen once as a trade off for it not automatically turning off

I tend to agree. I carry my S10+ in my shirt pocket and have noticed that AOD remains on.
Additionally, if double tap to wake the screen is on, the screen will wake on in your pocket without double-tapping it. I have disabled this feature as its annoying that this is also buggy!

This combined with the lift to wake option interpreting placing in pocket as lifting and the ultrasonic fingerprint reader activating in pockets is giving us of a real annoyance.
I hope Samsung are aware of this and do something about it.. .. ..

Very strange... just tried disabling double tap to wake the screen and it didn't stop it happening... Doh
It's a bug, they forgot to link the older aod behaviour with the new implementation of this sensor, I expect it to be fixed in the next update, along with everything else.
I'm constantly getting this too. Even with AOD off and the option to not turn screen on when in pocket(can't remember exactly name) I'm still constantly having my phone turn on in my pocket. At work I get a break every 2.5 hours and sometimes 45 minutes or more of that it'll be on in my pocket. I've pulled it out several times and the emergency call screen be on with a lot of numbers pressed. It's definitely a huge annoyance. My battery almost died during a 10 hour shift because of this.

Hi everyone. Any thoughts on this issue? This still persists for me even though my phone is up to date and it's may already.
I too think that there's a trade off with the in-screen proximity sensor and the fact that the phone doesn't recognise that's in a pocket. Mine keeps going on while in it.
There must be a way to get around this issue but I'm suspecting we'll never see an optimal fix since the proximity sensor uses that lit pixel to work and nobody would like to see it blinking every second.
I blame bad engineering here. Thumbs down for Samsung mobile.
I blame the new in screen proximity sensor. I doubt they will ever get a fix for their first gen type used on our devices. It'll probably be fixed on the note 11 or S11. I hope not though.

folks, its a bug in Oneui which existed in all S10 and s10+... its had been reported since day one and still Samsung still unable to solve this issues till date. And they published an notice in Samsung member app, next update will be addressing this issues finally. so lets wait for May updates and see they really solve it.

Proximity Sensor on Samsung A50

I'm pretty sure our A50s don't have a Proximity Sensor.
I don't use smart stay, but I do notice on phone calls that the screen sometimes goes from black to on at random times during the call. Is anyone else experiencing this? It's driving me crazy!

A50 have proximity sensor
When the screen goes black,you're near the sensor
On the screenshot you can see almost all our sensors (Sensor Box for Android ln Play Store)

Ah okay. Thanks - I downloaded that app you have and tested it. When my finger is right up against it it goes to 0cm. When I lift it off slightly it jumps right up to 5cm. Is that normal? What happened to everything in between?

I think pretty nothing as it is irrelevant. It is simple on/off switch for dimming screen when phone at the ear.
I guess so. I've just never noticed it so much with any other phone. I don't usually press my ear right up to the ear piece though. Usually I have about 1-2cm distance. Is there any way to increase the screen cut off distance?

The proximity sensor which we use in the mobile phones are with the capability of sensing any object comes in front of them . The longer it can sense is about 5 cm. The proximity sensor just sense the presence of object (within 5 cm) and not the distance between them . So it's normal.
Proximity sensor is there
Proximity sensor is present in all the phones and it is also present in Samsung galaxy a50 just that is very small and is present on top of the front camera..
By default the proximity sensor should be on for every phone but samsung galaxy phone in software it is off..
to check if your proximity sensor is on or off you would have to dial *#077692# in your keypad and the proximity sensor screen will open.. there you can the status.. if it is off there is a small button on top which would turn it on.. to check if the sensor is working properly.. put your finger on top of the front camera and if the screen goes green then the sensor is working fine without any issues..
Hope this fixes your concern..

Hi as the question says
Did anybody notice a small blinking circle (will be around 1mm size), around 1 cm to the right of the camera when you place a call on the note 10 +
or is it only me?
During calls I noticed it.

It appears to be the prox sensor (for turning the phone screen off when its up to your ear). That's what I've been seeing in comments of other people seeing the flashing during calls.

It is the proximity sensor.
And by the way it doesn't work well at all on my S10 plus. When I am on the phone the screen would turn on and then my ear would start tapping on the screen turning things on and off.
Pretty annoying, so I had to learn to manually turn the screen off with the power button every time before I answer or make a call...
I sincerely hope they have somehow found a way to improve it with the Note
just now saw it whilst playing a whatsapp voice message. when i put my finger over it, the phones speaker will shut off which seems to confirms its proximity sensors.
i did notice after some seconds, maybe a minute, the blinking light stops on whatsapp if you are listening to a speaker call on whatsapp... i have the whatsapp on full screen mode so the green part of the phones GUI is up there...
I noticed this today also when I placed a call. I dont make calls much so I just noticed it after 2 days. Just had some free time now and quickly rushed to locate this thread I had seen yesterday I believe.
What a relief it's the proxi sensor.

Working quite well for me so far.
It shows that Samsung has the ability to create camera under screen, but they didn't most likely due to photo quality
Good to know it's the proximity sensor.
Mine appears to flash rapidly more than blink though lol.
I thought I had a defective note. Thanks for the info.

It's the same thing just like S 10
those of us coming from the Note 9 that didn't have this, it's a new thing to discover...
When I first noticed it I thought dead pixel lol but it only visible during calls iv noticed
Yes, it is the proximity sensor, it is sad that this sensor implementation does not allow third party apps to use it, I used gravity screen in my past devices to turn screen off when in pocket or turn it on waving over the sensor, but now the app became useless, I use macrodroid, but it is not as good as gravity screen
does anyone else have a problem with the proximity sensor not turning the screen off during the call over telegram, threema etc.?

Question How to wake up my new phone with a wave (proximity?)

I just upgraded from an S8 to a 21 FE, I had this setup where my screen will turn off using the proximity sensor, so when I open my case cover or lift it up from the table it just turns on automatically.
Upgrading, I notice the apps I used (Gravity Screen, Smart Screen On Off) are not working as they used to. In most tests, I did seem to suggest the proximity sensor only responds when the front lens is covered by my thumb instead of just hovering over with my hand like before. I did the *#77692# test and the Proximity sensor is working fine then WHEN I enable it so I'm at a lost here, is this a technical issue, is this by design

A touch sensor while the screen is locked can consume less power than a proximity sensor placed in a camera, for example.
