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?

I think he means "accelerometer" when he says "motion sensor"

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.
Questions?

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!

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.

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.

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.

Question Phone calls suddenly shut off / false screen touches / bad proximity sensor

Just wanted to know if other users have this issue.
I do a lot of phone calls for my work and since I switched to this phone I can not make a decent phone call at all... lol
Every couple of minutes or less the call breaks off. That is either because the other side can't hear me anymore, either the connection breaks off.
Also noticed that when receiving notifications during calls, the screen lightens up so I do get false touches which results in a total chaos on my screen...
I already placed sim to other slot, tried all different preferred network type, rebooted...nothing helps.
This is really annoying as on my other phones like F2 Pro and MI9 all ok.
Anyone having the same issue?
EDIT : 16.04.2021 I noticed now that due to the bad ultrasone proximity sensor the screen lightens up and makes a lot of false touches resulting sometimes in a mute of the mic on dialer or even shutting down the phonecall itself

Yes, it has also happened to me that the screen does not go out when I am on the phone. If you take the phone away from your ear for a moment and then go back to it, the display goes off.

Yea I already tested that before this post. It's working fine. No problem with that.
Problem is that when receiving a notification the screen lights up and it shouldnt. I cannot find the issue for now.
Also and this is more important : when making a call, the line gets cutoff (people cant hear me but I can).
This happens so often and never had this with my other phones running.
Already unchecked 5G, even 4G and now on 3G. Same issue.
Will look further into it...

Do you use always on display ? Maybe that's the cause? Maybe Miui optimization?
I didn't put sim card from my f1 to f3 yet, but you are making me check this out. Ill put the sim card as soon as I get case and glass. On telegram I have not seen anyone to mention this issue.

Nope not using AOD. Things are set to basic as to rule out issues.
Saturday I'll be unlocked though and going to check the fastboot xiaomi.eu rom
If you can make a test later on, do make a longer phone call. Also send a message to your phone when you're making a call and see what happens.

Yea I read.
Anyway, the phonecall shutting off (other cant hear me) was all due to the fact that I accidentally muted the mic (or even false touched the red button or whatever) on the screen because of the false touches when screen suddenly lightened up.
The ultrasone proximity sensor is not the best solution to dim the screen when calling.
You can even test that in kernel settings. The value 5 goes to 0 even from behind or from the top. So in some cases the screen will light up suddenly.
On tweakers forum there are a lot of people who have the same issue with the proximity sensor too.
An infrared sensor would have been much better....

I have a similar issue. I use a pretty thick case and it breaks the proximity sensor such that during a call the screen turns off but after the call when i move the phone away from my head, it remains permanently off, like it still thinks the phone is near my head.
Which tweakers forum are you referring to?

That's indeed true. It happens that the screen remains black after moving the head from the screen during call. You can even trigger that when opening the sensor part in the kernel (tap on it for a few times and test the proximity sensor - you'll notice that you even can let it stay on 0 by slowly removing your hand...)
But for me these false touches due to the screen lights up during a call makes it even worse.
tweakers translate if needed - starts from end of page 6.
Btw, I'm just using the case that came with the package.
Anyway, since they fixed the haptic crackling sound issue on v1204 eu and having already no issues on battery drain (9%/h SOT and 0.4%/h idle) , the only issue for me remains the proximity sensor.

If you pick up the call and wait 1sg or so to raise it to the ear, the screen turns off well, but if you pick up the call quickly it does not turn off, it may be a google dialer failure

Perhaps you can bring this issue to Poco's attention directly via: https://c.po.co/global/
I would also like to know if it's a hardware or software related issue.

For me if I use the case that came with the package, proximity sensor works fine , it also works fine if the phone is naked. but with a thick case, then it becomes a bit crazy such that i have to map the power button to end the call, else I wont be able to access the phone after or during a call unless i shake it hard

I really hope it's a software issue because I plan on placing my order for phone this weekend.

I wonder where's the proximity and ultrasonic sensor. *#*#miui#*#* can't test it. Using nillkin's case, one works perfectly, while the one with the thicker camera protector blocks the sensor and calling won't dim the screen.....

experienced this with the global rom but now flashed EU rom so far everything is ok.

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...

I don't think so, I've already tried to wipe it, but nothing changed! I have this problem since first day... I thought they resolve it with an update, but after 4 months I'm still waiting

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
