proximity sensor - Essential Phone Questions & Answers

I am 100% stock no fooling around yet (hotspot is my must have) surprisingly it works right from Sprint store! I have an issue with my cheekbone hitting the mute button 75%of time I answer calls. Took me a while to figure it out. I thought it was a phone issue initially till I noticed it was white which means on. Any thought on solution? Sucks having to be aware of it ever time I answer now, instead of just you know the thing going dark a moment before contact is made! Thx for reading hopefully

I thought I was the only one with this issue haha
I had it with my oneplus 3T as well.
This might not be the issue in your case but I found I just hold the phone oddly under normal circumstances.
I diddnt realize it but I hold it a bit off center on my left ear causing the proximity sensor to miss me.
this turns the screen on and like you I end up muting it most of the time.
I figured it out by taking it off my ear while on a call and using my hand to cover the sensor. (it turned off the screen right away as it should)
then I just experimented with placement until I realized what was happening.
it diddnt happen with other phones I had but I realized they all had smaller screens so it wasn't as easy to hold them off center without noticing.
I found I can consciously move the phone center and see the screen go off out of the corner of my eye.
unfortunately that's a bit more focus than I like to put on it so I usually just end up hitting the power button while on a call which turns off the screen and it wont come back on until you manually turn it back on.
on a side note I used to have a cheap nokia windows phone that was inexpensive enough they did without the proximity sensor.
Instead they had it so when a large enough area of the screen was touched it would turn off.
single touches kept the screen on so you can still pull it away and mute or put it on speaker etc.
I kinda wish more companies would do that instead of the proximity sensor, but I think I'm in the minority as you are the only other person I've heard say they have that issue as well.

Ha, I'm not alone! Thanks for the tip, I will do some fooling around and see if maybe I'm holding at funny angle. I have been rooting since my first smartphone (HTC Evo 3d) for hotspot consequently. Seems even back then, especially on HTC phones the proximity sensor was a problem so I'm surprised I was clueless for as long as I was. That was a total bug tho. I would be talking to someone and open 4 apps and turn on airplane mode,take a screenshot, I even composed an email of gibberish and sent it to my son because the screen would not shut off Who knows, it was less than optimal. This is not a bug it seems either as you astutely pointed out I may be bringing it to my ear oddly enough to hit it before the sensor senses, ha. OR it is a hair slow. Who knows could be worse I could have a Samsung or Apple HA!

problem while talking on the phone

Does anyone have an issue with your cheek pushing buttons while you are on the phone? I am running liberated_aria and whenever i am on the phone, my screen does not shut off like other phones and I end up either hanging up on people or moving widgets and even adding widgets..
has anyone else noticed this? is there a fix for it?
Its happened to me once on an Aosp rom. Haven't had any problems after that though.

I haven't had any problems. The proximity sensor is on the top right of the phone, where the AT&T logo is. Try making a call, to voicemail or something, and then waving your finger over the sensor. Does it ever turn the display off? Could be a software bug I suppose, or just a faulty sensor.
if you use your left hand/ear its pretty easy to dodge the sensor, unfortunately.
I tried a call using my right hand and I dont have that problem. Only the left.. I guess Ill have to start making all my calls right handed.
It figures...
Us southpaws always get the short end of the stick. FWIW, I almost always hold my phone(s) left handed, and only rarely seem to have this problem. ( It might just be that I have a huge head, and big ears. )
Im a righty and sometimes when making calls i get a haptic vibration from my face touching the nav buttons i think, nothing happens though.
My girlfreind is having the same issues with her handset.
We found her an Aria about 2 weeks ago at Best Buy Mobile for $1. They are running some great special for non-iphone handsets. The Aria was giving her problems and we ended up exchanging it. The 2nd Aria also has the same issue. While on the phone, her cheek will press random buttons and even hang up. Sometimes she just feels vibration, sometimes its a number pad press, and sometimes she just hangs up all of a sudden.
It seems to be some sort of sensor issue. Does anyone have some insight as to how to fix it? It's kinda of a big deal if the phone function is impaired by having to hold it away from your face.
Thanks!

Other then making sure her head is covering the sensor, she canlock the phone in mid call and it should stop her phone from registering her cheek while on a call

Huh. I'm a righty, but I talk left hand / left ear, and I never have any problems. Do you tilt the phone in some strange way?

Thats a good idea. Thanks.
This issue is really pissing me off. I love this phone a lot but the proximity sensor is not working as it should, atleast with my head shape.
Seems almost in every other call I make/receive my cheek contacts the screen and pushes something because the proximity sensor is not detecting me head.
I've tried locking the phone with the button on top of the phone but that does not work, it's only temporary until the proximity kicks back in.
And, the funny thing is, when I try to "test" it out or replicate the situation I can never seem to do it again! It always happens unexpectedly.
I'm in the same boat with this too, but it's a hit or miss thing and really could be much worse.

i can't say i've ever run into this specific problem. i've actually been impressed with how well the sensor has been working.
i would agree with the previous poster who suggested to lock the screen once the call is active. make your call then tap the power button to lock the screen and that should help you avoid the issue.

Weird in call behavior

While im in a call on my G2 randomly the call will end or it will get muted or it will go on speaker phone. It seems like there is a proximity sensor or a light sensor in the upper left of the phone and randomly it freaks out mid call and turns on the screen and my cheek hits some of the touch buttons. It is very annoying. Randomly ill be in a conversation with my girlfriend and it will hang up -_-. maybe when we get root access or more api access to that sensor we can turn it down or something like that. Anyone else having a similar problem?

This is a common problem with smartphones that use proximity sensors. Whether or not you get this problem depends on how you hold your phone to your head and possibly whether you have long hair (there is some argument about that). Some phones also do have more problems than others, suggesting it might be related to programming of the proximity sensitivity/hysteresis.
I see. I actually do have long hair... that could be a factor. My hair could be moving across it or moving and it could be triggering the sensor. Maybe once we get root access we can see if there is a way to disable the sensor altogether for calls. I like the auto back light feature but so far in calls it is very annoying. Shouldn't be too hard i think.
One thing I like to do is cover the top part where the sensor is first with my ear / side of my head then place the rest of the phone on the side if my face. So angling it basically, whole process takes about 2 secs. Hope this helps.
fRom Snugs G2 ^.^
I have the same problem too, its annoying. What I do is that I try to keep the sensor area (top left of the phone) as close as possible to my case, also as covered as possible. Kepp the bottom half of the face a little bit away from the face (cheek). - this way you wont set off any on screen buttons if light does get through the sensor.

Wife' X keeps hanging up calls with face

The proximity sensor seems to work. Is there a call screen replacement with a slider to hang up?
whens shes talking lock the screen via the power button and walla
If you're rooted, there are many applications that change the proximity delay in the build properties.
You could try that.
Or ya, manually turn the screen off with the power button.
My mother has owned her X as long as I've had mine (since day 1) and still hangs up on me almost every conversation.
I personally just angle the phone slightly away from my face along with the sensor delay changes I mentioned.
If she is like my wife she doesn't hold the ear piece to her head while she talks (thus the proximity sensor thinks she isn't near the phone), then she hits the screen on her cheek and hangs up on people.
Tell her to learn how to talk on the phone properly.

Yeah, and report back on how sore and stiff you are from sleeping on the couch!
I don't understand why anyone would want to hold a device the size and temperature of a smartphone to their head.
I started using a BT headset when I bought my Treo 700P and have been using one since.
I actually did sleep on the couch last night, different reason.
I ended up teaching her to use the power button to turn off the screen.

Sounds fun.
She no longer hangs up on a call she answers but she constantly mutes calls that she makes now. My phones rings and I'm like hello...hello...
Sell it and get a Razr flip phone. At this point there is no more help.
Let me guess, Blonde?
Be nice kids.

Proximity sensor kind of wonky/bad?

Anyone else have proximity sensor issues on the G2? Ever since I got it, it's been very wonky, even when it was purely stock. The worst problem is often when I take the phone away from my ear it doesn't turn back on, and then it seems that the knock on sensor stops working, and I have to hit the power button. Sometimes when I put the phone to my ear when getting a call the phone goes to sleep and the call gets cut off.
I do have it set to automatically answer the phone when I raise it to my face, so maybe that's an issue. I'll disable that and see if it helps.
Anyone else? I'm kind of bummed as I use my phone as a phone first and having something like the proximity sensor work is absolutely crucial in my phone use.

I've noticed that everything works well with this. Surprisingly so. On the s3 i would always get the black screen issue when pulling away from my ear. Ringtone even lowers as i pick it up. I could never get that to work on my s3. Not that, that matters.

Yes, but not all the time. When it does happen, i can't get the screen to come back on at all until after the call ends. It doesn't do it on every call but when it does it's really bad.
I'm running tge Verzion Clean Rom right now but it did it on the unrooted stock too.

Unintended taps during call: how to prevent them?

Hi!
I"m not the only having the problem: during a call unintended taps takes place while screen waking up is not registered during the call. So, you see, I'm not sure a proximity sensor is the reason of the problem as far as screen is kept turned off.
I have tried to reproduce the issue by fingers, but wasn't lucky.
Have you any ideas how to eliminate the problem?
I mean not-rooted official up-to-date stock firmware use case.
And, by the way, I haven't found proximity sensor calibration in service menu for A1. Is it placed somewhere into another place?
That happens to me all the time too.
Yup, me too. While in call I sometimes unknowingly turn on the flashlight and probably look like an idiot. ?
With the rn3p I would constantly end up muted. With mi a1 the problem is much less although I've noticed that numbers are still pressed. I've learned over time to switch to keypad so when something gets touched it's not the mute and at worst the other person receives some key tones.
I also have this problem a lot. I mute myself 9/10. To bypass to problem, I just lock the screen before placing it against my ear.
Yes, a simple soutions is just when you call someone, imidiately press power button to lock the screen (no password or fingerprint requred to unlock)

That's what I've been doing. That and pushing the top part of the mobile on my face just to make sure. lol
Oh and use the Feedback app and send it to xiaomi and hope they fix it on the next update.
i had this problem too, has it been fixed in the latest of updates? its a really annoying bug.
You must be doing something wrong. This issue "must" have been in all smartphone operating systems in the world, if what you are saying is the truth.
There's no way to drop the call, or press anything while you are calling someone. The proximity sensor doesn't allow turning on the screen when it's close to an object. The gyroscope also turns off the screen when you rotate the phone vertically during a call.
But all I can say is that it's not a bug, this is how is your phone knows when you are in a call, and you put your phone to your ear, or when you use your "speaker", and so the phone knows it's supposed to used it's speaker to transfer voice through the call.
Beside my poor English, try to move your phone a bit vertically before putting it close to your ear.
same problem here, also disabling ambient display... i also tested proximity sensor with some apps and it seems ok
I have that problem too from the beginning. None of the updates came up with a solution
Same here: I mute, turn on the flashlight or even open apps sometimes with my face. And thanks for the input @SmallTarzan but i know how to operate a smartphone and did not have any similar problems for the last five years. Apart from that annoying bug it's a great phone.
Wow, i dont know of this bug since i'm using custom rom from very beginning.
Try to make a call then use your hand to cover top part of the phone, screen doesn't lock??
I am having this issue too and it is really annoying
And still nobody came up with a solution???
It's easy to understand why it happens.
Proximity activates while you're in a call, but apparently the touchscreen digitizer remains working (even though the screen is off). Touching the digitizer with your ears or cheeks activates different actions while you think your screen is locked.
I can't believe how this issue is not fixed yet! That's a shame!
Same applies for the network fluctuation issues. You need to either choose 3G or 4G to avoid loosing your data connection.
Xiaomi that's more than LAME! You need to be ashamed of yourselves.
It happens to me quite often, although not always.
It's more frequent during long calls. If the call lasts for less than a minute or so, it doesn't happen.
Proximity sensor works, and screen turns off as soon as I put it at my ear.
Keyboard is off and not responding for a while. Then, all of a sudden the phone comes alive.
In my case it's not the torch. What I activate unknowingly is the handsfree loudspeaker, which can be even more embarrassing, sometimes.
Maybe it's because I am left-handed.
In an attempt to have the proximity sensor fully covered by my face, I tried to make calls by holding the phone with my right hand, but to no avail, after some time the screen wakes up regardless of everything.
Happens to me too. Although I did notice some differences regarding the position of the phone on my ear or which side of my head I put the phone on, I started pressing the power button long ago to turn the screen off. It may not be ideal, but it takes care of it.
