Question How to wake up my new phone with a wave (proximity?) - Samsung Galaxy S21 FE

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

Didn't you find the gesture to double tap the screen to wake up?

I did, but I'm used to waving my phone awake with both my hand and by opening my phone case, but it seems the more recent Galaxy phones don't allow the same use of the proximity sensor

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

Face Recognition App

Do you think someone will make an app that will detect your face and unlock the phone now that we have a front facing camera. Also what is the motion sensor used for?
That'd be awesome

Sweet. Hopefully it's hacked with front camera access and the ability to enable it by holding the volume rocker to do the scan. Hopefully you don't wake up one day looking really ugly.
Lots to hope for LOL
It would be nice to have the camera key on the side though. There already a couple of face "detection" apps out there, not recognition though. Photofunia, in market, takes face and puts in various backrounds, works well

One example of the motion sensor is that when someone calls you, the Evo quiets the ringtone when it detects you've moved your phone with the intent to pick up the call.
It's actually a proximity sensor, used to turn the screen off when it's held close to your face. The feature of the ringer quieting on pickup uses the accelerometer.
So what does the motion sensor do?

The Light sensor via front of HD2 disables touchscreen of device when held close to face! The motion sensor is used for screen rotate and other apps that work well with phone positioning commands!

The light sensor has nothing to do with disabling the touch screen. Its used to change the auto brightness of the display. The screen shuts off when on the phone because its turned upright.
Well that's how it works on the evo. So I would think the same for hd2 that u mentioned in a evo thread...
It is turned off via proximity sensor not accelerometer

Ahh, but u can hold the phone next to u and the screen won't come on till u tilt the phone horizontal...anyway its not the light sensor...And yes a face recog app would be very cool to have...
People, people! Please!
1) Accelerometer: Used to detect changes in movement. Used primarily in Android for apps such as Bump, or to rotate the screen, or games such as Teeter and racing simulators (tilt phone like you're turning the steering wheel, etc.) Also known as the motion sensor.
2) Light sensor: Used to detect ambient light so that when the phone's brightness is set to automatic, it knows to increase or decrease the brightness of the screen appropriately.
3) Proximity sensor: Used to detect if something is near the speaker and of the phone. Mainly it is used to turn off the screen and touch input when it detects something near its front, and a call is in progress (aka, detects the side of your head near it, so your cheek doesn't accidentally push any buttons).
As for the facial recognition, yes, that would be nice, but what happens when you get a haircut? Put on glasses? Have a zit? Get a black eye? Swollen lip? Sunburn? Grow/shave a beard/mustache/etc.? That's the problem with these kinds of software, and why all computers that have facial recognition will always have a password or some other kind of backup authentication.

no... asus laptops have the face recognition systems and it works GReAT!!! no problems whatsoever... but thats b/c u can put sooo many pictures and set the sensitivity of the security on the camera... its pretty sweet

It's also a laptop and you still have the password login as a backup. Believe me, I used to cell them and had to reset the password every other day because bratty little kids came in and thought they were smart and tough by setting the camera login to themselves making some disgusting face, and the password to "toughguy" or "password".
Wow!!!!!!
is this app out yet? Couldnt find it on the market..

*This was posted from my Evo 4G using Tapatalkpro! Great app, if you want to browse and post through many dfferent forums*
Would be pretty great!
Lol at the misinformation, thanks for clearing that up for our slower folk.
This is definitely gonna happen sooner or later.
It would need a backup method of course but if made properly it would be more general and little things wouldn't change the outcome.
I was thinking this...
You take 3 pictures the first time you open the app.
It merges them, aligns the face and sets a gaussian blur to smooth and remove imperfections.
Then it cuts out things like hair and eyebrows leaving behind the static parts of your face such as eye shape, nose, mouth, jawline and cheekbones.
It basically takes the 3 specific pictures of your face, and generalizes them, while keeping them relatable to every future pic.
I think its called interpolation, which gives you the perfect identifier, ultimately being used to recognize you.
Of course a setting would be needed to change how similar the face needs to be before being granted access but theres no reason it wouldn't work.
My other going thought is an app that learns as you go but it won't work as well.
nope again!

iTS AN OK thought of how it works but my HD2 can be of any position even flat down and as long as I am in a call and i put my finger over the light sensor (same as face, ear being close to sensor not letting hardly any light get to it)
the screen disables! I think many of you may not have the HD2 if ya didn't know that, don't let internet chat and gossip get in the way of the truth, truth is within the device when holding it, not hear-say. Also why would the accelerometer have anything to do with disabling screen when in an upright position? If one was to lay down in bed chatting on fone, my HD2 would un-disable screen... Try an app called mToolbox, it emulates what light sensor and motion sensor can be used for. I would say, light sensor can be more useful in many more apps than motion, motion works great with changing screen from portrait to landscape and movement in games.. An app to control ps3 via bluetooth using HD2's accelerometer feature would be useful, but for now, i have tweaked it to off, I have many older WinMo's and find using the screen orientation key much more faster and when i need it, it gets annoying when the screen changes at unwanted times and no matter how you calibrate any accelerometer, there are flaws to it depending on what situation one is in when holding the device (fone must be upright again to go back to portrait if fone was laying down) sorry for the long babble but I'm certain that the light sensor own's the screen shut-off feature on the HD2 for sure.. Quote me again any time!

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.
Sent from my SGH-M919 using xda premium
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?

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..

proximity sensor is located on upper left corner just above the screen. u can see it in action during call through another camera.

Proximity Sensor not working?

I've been using Tasker to keep my phone off in my pocket with a combination of 'orientation on right side' and 'proximity sensor' active. Googling a bit, I see some mention about a software upgrade breaking the proximity sensor not long ago.
Anyone know more about it? Sensor seems to work ok when phone is on - maybe it got broken for non-phone things?
(note - turned off double-tap to wake & lift to wake to try to keep phone off when in my pocket)
since s10, proximity sensor is internally controlled only on certain activities. example: phone calls

I was just researching this again & found this, which matches what you say:
The proximity sensor is indeed under the screen and a pixel has to be turned off for it to work properly. This means proximity apps will not work properly any more unless Samsung writes them.
So Samsung turns off a pixel so that the Proximity Sensor can see/work (like during a call) - and that means my Tasker screen off will not work. Wonder if there is a Tasker "if front camera covered".. gonna go look that up now - actually that won't work, would require the camera to always be on.
Hmm.

I was trying to play with the light sensor with no luck - so I stripped my profile down to just Orientation Right Side = off...and it failed. The screen off works when i manually test it in Tasker, not sure why orientation fails too.
Maybe this is for another thread - what the heck are people that keep the phone in their pockets doing? I've read keep screen away from leg which is a pain for me and the flygrip I use on my phone. Must be a better way!

Touch screen problems? Maybe actually proximity sensor (which is terrible).

One of the touch screen issues I sometimes experience is when swipes are "broken" and register as shorter swipes and taps. This makes me think maybe the accidental touch protection, which is supposed to be triggered by the proximity sensor, is being triggered when it shouldn't. We all have read complaints about how the proximity sensor does not work very well.
So on a hunch, last time I had this issue (trying to swipe in gboard), I stuck my finger on the front-facing camera, and interestingly, swiping worked fine (I expected the screen to be disabled - guess that only actually is supposed to happen when you're on a call?).
Since this issue is so random it's hard to really test it. But I've had quite an experience with the proximity sensor.
I wanted the AOD to turn off when the phone is in my pocket, which is the norm on other phones I've used but for some reason Samsung does not do. So I set out figuring out how to do this in Tasker. I got a sensor test app and noticed the proximity sensor basically has two values: 0.0 and 5.0. It is very slow to respond (slower for "uncover" events) and seems to only switch to 0 if my finger is right on the camera. So I set up Tasker to turn the AOD off if the proximity sensor value is < 1, or on if it is >= 1. I also made it vibrate briefly so that I could tell when the sensor was toggling even if I couldn't see the AOD.
At first it worked fairly well. If I manually covered and uncovered the camera, the AOD would dutifully toggle (not instantaneously). But in "real life" practice, it turned out to be quite unreliable. There would be phantom proximity changes while I was using the phone or carrying it -- most interestingly, it often toggles the AOD off briefly when I pick up my phone -- but I didn't really notice any surprise vibrations while the phone was in my pocket. After a couple hours, when my living room got darker (not completely dark), the whole thing went crazy and the AOD would toggle every few seconds with the phone sitting on a table.
So I think the whole "let's ditch a dedicated proximity sensor and use other things to get the same result" is not quite mature yet. And perhaps it is buggy enough to cause one of the issues we think of as a touchscreen one.
