[App Req] Proximity Sensor Screen Off for Flip Covers

hey guys!
I am using a flip cover from Rock for HOX. I love the app called Smartcover which let's me use my cover just like the smart cover of ipad using the proximity sensors.. but, I am getting a feel that it drains my battery like anything..
now, I wanna know if someone can suggest an app which is low on battery drain for using this amazing function.. Also, wanna know other's take on the battery performance using this app..

Hi there! You could try Proximity Screen Off from Google play. I had it and it didn't seem to eat lots of power.

If you have a look at the permissions required for that application you can see it has permissions to keep your phone awake.
The proximity sensor is off when the phone is in standby, I suspect this is a hardware limitation, i.e. the proximity sensor isn't it's own independent hardware device but is partly software driven and requires the phone on to work.
For your application to work, it has to stop the phone sleeping in order to get a readout from the proximity sensor, and so your battery goes flat quicker.
I doubt there is any application that can change this behaviour as that is how the proximity sensor works, it needs the phone on.

I tried using this app.. this helps in switching the screen off but it wont switch the screen on once I flip the cover.. so doesn't work exactly how I wanted..
while browsing through XDA, i found that ppl have developed apps for the same purpose & those are really battery drain free.. so was wondering if the same was possible with HOX too...

I use Smart Screen Off, you may try it. Prefer over Proximity Screen Off. It don't lock the screen if you have security lock on.

Knock on and keeping G3 in a pocket

I love Knock on feature but after 4 days of active phone use I find it rather annoying!
I usually carry a phone either in a back pocket of my jeans or in a shirt's pocket.
So every time there is a little pressure on the screen it turns it self on and weird/random things start to happen to home screen.
I don't use password or swipe protection, so when I wake up the phone it immediately goes to a home screen.
The knock on sensor seems a bit underdeveloped. It needs to be less sensitive to non-finger pressure.
Basically after 4 days I gave up and disabled it.

I have the same problem, I disable Knock on unwillingly...

The quickcircle case prevents this issue (and looks pretty snazzy, too).

I suffer from this prolem too. The weird thing is, the first 3 Days with the phone, this problem was no problem...I don't know why, but since yesterday, it appears frequently...Maybe I wear other trousers? I don't know. The sensor on the front should prevent the phone from waking up while in the pocket, you can test iot working by cover the front sensors and then "knock on"...it won't work. That is exactly what should happen inside the pocket, but however, it does not work properly for me!

Just curious. How did you know the phone was on because of the knock on and not because the power button was accidentally depressed?

Because I turn off knock on and now it's fine

Hmm, I carry my phone in my jeans pocket all the time, and this is not a problem to me. Knock on never seems to trigger when I don't want to.

I have had no false starts from using knock on at all, I even tested with lots of different materials to see if it would work.
If it is causing you such problems why don't you use a knock code?

Just like these two guys, I have no issues with knock-on - if anything when I take it out of my pocket I have to triple tap sometimes to get it working.

Put the phone in the pocket with the screen facing outward as a temporary solution until LG fix this issue..

It is a very risky workaround and i'm aware of that
but the thing is, even with any type of security the screen will turn on once it gets inside the pocket and it wouldnt turn off..
so theres definitely something wrong with the proximity sensor..
anyway i solved my problem by using the QC case.. and apart from this issue it's a great case overall

this happens to me too, but only with loose pockets. when i'm wearing my office attire, theres no issue. But when i'm in shorts during the weekend, it turns on by itself and it gets quite annoying. sometimes it'll open apps and start typing gibberish.

Dial 3845*#855# then scroll down and you will see a menu to disable it.
Substitute 855 with your model number if you have a different one.

[Q] Knock On doesn't work on charger or sometimes

Sometimes after some time I'm not using the phone knock on doesn't work. Today I noticed it didn't work whole time when on charger. I wake it up with back button and it worked normally. Then I put it on charger again and same thing happened. Is this normal or a problem ?
I'm running stock v20h.

Same problem here... Any solution? Anyone else has noted this?

In my case the problem was that the desk was over the phone so proximity sensor was turned on and didn't allow me to use knock on. It is probably made like this so it won't unlock by itself in pocket.
See if that is the problem. You can cover proximity sensor with your finger and try to use knock on to unlock.

No way... iti's still not working. While charging (plugged to the wall) I have to "wake it up" with the back button, nad then unlock with the knock-on code.

That wasn't my case. I can only advice you to backup your data and do a hard reset. If that doesn't help take it to the shop.

Finally, I realized that the problem occurs only while using a charger with less amperage than the original one.

AOD still stay on ?

Does the AOD stay on when the sensor covered?

Which sensor? AOD stays on (based on the preference setting though) when the display is off.

Stays on, in S20+ (has to be the same in Ultra).

AOD will turn off when the phone decides that it is in a pocket or in a purse. It uses the gyroscope, accelerometer and the proximity sensor for that. I just covered my proximity sensor and AOD went out in about 20-30 seconds. When you take out the phone out of the pocket, you may not notice the AOD turning back on if the phone worked out that it is being taken out. If you are fast enough or the phone is too slow to determine what is going on then you can notice how the AOD wakes up. In addition if you have raise to wake option on, it will be hard to notice since the whole lockscreen will show up.

I had the phone flipped over on my desk for several minutes. I can see AOD still being on. I assume this is one of the scenarios that it should turn off?

Seems like it's the same as the s10plus proximity sensor then. Cheers.

Question Any software solution to proximity sensor failure on calls?

Hello,
Before buying the Poco F3 I've never had a phone with this system without a proximity sensor, and the truth is that after using the phone for two weeks I'm sick of it. I'm even thinking of selling the phone.
Due to the fact that the problem is related to the lack of appropriate hardware, I think that a possible solution for phone calls could be that the screen would automatically lock when answering calls, and then to manipulate the screen again it would be necessary to unlock a via a slider, pattern, fingerprint, or facial recognition.
Do you know any solution or calling app that allows to do something about this? Root wouldn't be a problem.
Thank you.

I tried the recalibration but did not work. Also I am using a new tempered glass screen protector but no luck. It would be interesting to hear from someone who is using a custom ROM if the problem is solved there

you want poco f3 to go screensaver mode/ blackscreen when your calling/talking to someone?

Unfortunately, they have to use palm rejection in conjunction with the camera to get it to work but it will never be as good... I know that feeling bro... hate how when listening to audios on Instagram or whatsapp this **** doesn't even work at all

I checked the proximity sensor test in CIT and it is very inconsistent for me too. I guess this device has an ultrasonic proximity sensor instead of the infrared sensor that is generally used, and it hasn't been calibrated correctly. Maybe future updates could fix it hopefully

i use this app name "proximity service" when you cover the proximity sensor near front camera the screen would turn off while the running apps does not get shutdown i use it to stream call of duty without my phone screen running so phone don't get overheat

so is the proximity sensor actually broken on everyones device. what the hell something as simple as that they messed up.

provably intentional they sacrifice some hardware to fit its price range this explain why the phone cost $200 on some country while other have it at $400

I think proximity sensor is an essential part of a phone during they haven't left it out. Must be software bug.

As far I know, this phone don't have any proximity sensor, I guess that this is because design reasons, don't think that the proximity sensor hardware cost more thant cents. The phone uses an ultrasonic "sensor" combined with the gyroscope, because of that, the sensor only works (when it works) with the phone in vertical.
For Whatsapp, instagram or other audios I don't think there is a solution for this, even with future updates, since the main problem is the lack of hardware and isn't possible to modify the apps.
I thought that a "solution" for phone calls could be that if when answering calls the touchscreen locks automatically (even if the sensor malfunctions and don't turn off the screen), and for unlock a slider on screen or something similar was necessary, could be a solution for misstouching the touchscreen with the face. Even using screensaver mode/blackscreen for this purpose could be a solution, but I can't figure out if this is possible with some other third party telephone app.

Are proximity sensors needed?
I am thinking about buying this phone, but this concerns me.

I already bought it and found out about this sensor issue after purchase the phone is on its way and i am kind of regretting the purchase because sensor is quite important so that the screen can go off when the phone is near your ear and also for some reason when playing voice note on whats app people are saying the screen turns off and doesnt come back on which is a huge flaw in my opinion. I cant think how this could possibly be fixed without the option of a physical IR proximity sensor.

Ok maybe Hold off a while until more is known

I am also experiencing this same issue. Due to this, I had sold my previous device Mi 11Lite to a friend of mine since he isn't bothered about the issue. Now in Poco F3, I am facing this issue. Sometimes it gets off and sometimes it doesn't. Initially, I first experience this issue in Redmi Note 9S but then the same issue arises in Mi 11 Lite. But in Poco F3 it does more frequently then my previous devices.
I think it's due to wired location of the proximity sensor which controls it in these thin bezels devices since the earphone grill is too small. Its driver or software should be tweaked by developers or Xiaomi in sort of patch or update.
If there is any fix or workaround for this then kindly share since it's very annoying especially listening to WhatsApp messages is a pain in the ass.

Also my f3 when I make a call and phone is upright and my face is facing it then the screen goes off. This does not happen when the phone is lying down

i thought that what supposed to happen? also forcing your proximity sensor to "always run" and detect if your phone put down on table lying down and turn off screen would eat more battery

Yes, for example when you're lying on the bed or the couch and want to attend phone calls and hear whatsapp audios.
