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.

Screen stays off throughout the call.

Hey friends,
I am facing this problem while making calls that as soon as I press call button or receive button(while taking call) the screen turns off n stay that way till the call ends.
I have tried pressing all hardware buttons,even moved the dvp awayfrom me n into direct light but to no avial.though it did turn on once or twice out of twenty times.
Did anyone else experience this? Any suggestions are welcome..

Do you have a screen protector or case that is obscuring the light sensor or proximity sensor? My first guess is that something is obscuring one or both, because during a call the screen being off is a feature.

screen stays black/off during call
The screen stays black during a call and this happens ramdomly. I have a dell venue pro a t mobile phone but it is a pre release so it works on att 3g and all. I have switched the sd card with no improvement. I have ordered a transender 32 gb sd that I haven't received yet. The firmware version 2250.1400.7004.025 hardware is 112.576.2.0 radio soft 2.2.50.14 radio hard 8250. I have been unable to get any of the hardware keys to hang up the phone which if I get voicemail or something means I have to power the phone down to get the dang thing to hang up. Sometimes it works fine but I cant find a commonality software or hardware that causes this. It happens right out of the box so even after a software reset it can happen. Is there any solution for this issue?
I can't understand why the button on top doesn't hang it up.
PS I got this phone for free and I got ripped off LOL

wow just got a replacement phone today and im having this problem, As soon as I go to make a call the screen goes black and cant do anything on screen during the call, so i cant enter my password when checking voicemail

I think it's related to the proximity sensor. When you put the phone close to your head, the screen switches off. When you move it away, it will switch on - most of the time .
If it stays black, have you tried tapping the power button on the top of the phone? It switches the screen on without disconnecting your call.

A coworker got a replacement the other day(they send a refurb) phone and it had the same problem. Had to go through Twitter to get Dell to send him a new retail phone since they had send him 3 refurbs prior and they all had different issues.

This is just a general statement regarding phone proximity sensors. I have had multiple phones made by different manufactures that experience this to some degree (including the Venue Pro). One thing that I have noticed is that if the phone goes from your face directly into a bright light (outside is most common) it will keep the screen shut off but if the sensor is somewhat shaded it will resume normal function.

I got the same problem too and while it may be a proximity sensor problem, it is not controllable on the user's end. Unless the phone call disconnects magically, a battery pull is necessary.
I'm gonna be on my third one soon and I hope that i won't face the same problem.

Yes i recently got a new refurbed phone and this problem has arised. Complained to Dell and they are going to send me a Brand new DVP. I see a lot of people having this same issue with the refurbs. Currently Dell is out of new DVP due to them upgraing the firmware, so I have to deal with a broke phone till the end of August. Talk about a dissatisfied customer. Im thinking about selling this brand new unit when I get it, hopefully Toshiba has their device out by then

This is a Proximity Sensor issue. You can fix it though in the EM app. You can adjust the sensor readings and the phone will function like normal. Let me know if you need the values or a step by step!

A step by step would be awesome. I like being able to see the screen during a call.

1) Get the EM app, if you dont have it dial ##634# into the dialer
2) Get into the advanced menu by double tapping the black area and typing in "qwertyuiop"
3) Select "RD test", now enter *#6336# in the box that pops up.
4) Select "Sensors", and the "Proximity Sensor Config"
5) Set the following to these:
LED strength - 1
Diode select - 2
Pulse Count - 43
6) Hit set and then you are good to go!
I have noticed that one of my DVP's needs to have this put in again everytime I reboot the phone, the other saves it. Just an FYI for ya!

I get to step 3 and when i clock on RD test, I am prompted with a white box with blue trim and an X at the top right. can you advise on how to proceed?

Oh yeah, Im sorry I forgot that part. Enter *#6336# as the password.

When I dial *#634# it says thic code is not supported.
What does that mean?
I put in a different number combo before and it put me in the EM screen

Knock knock not as responsive waking up...

Sometimes I have to knock knock twice in a row to turn on the device. It works well turning off, but on half of the times it won't turn on. Gotta do it twice. Anyone else encounter this?

I do not have that issue, but I have read in a few posts that it can be dependent on where you are knocking on the screen.

I think the biggest issue is knock speed.... mine works damn near 100% when I slowed down some, and knock slower like it showes at the end of the G2 commercials....

I think it's partially related to the proximity sensor. There are times when I can't get the knock on to work at all and when I hit the power button the screen shuts right back off.
Usually a few swipes over the sensor makes it work again. Sometimes I'll go in and turn the Knock On gesture off and back on and then it seems to work great for a while too.

This is my exact problem. The phone just decides it doesn't want to wake up with knock-on...but after I press the power button, it only turns on for half a second and it's out again. I never tried swiping over the sensor, but hopefully it works because it's mighty annoying when it does it during a call!
I wonder if there's a fix for this?

this, if you are trying to do it like you did on the nokia n9 or nokia 8800 then it won't work
slow deliberate knocks are the only way
waiting on the g2 to arrive, but on my review unit, knock knock wouldn't respond correctly if i left the phone on the table, but if i picked it up, it would work nothing scientific here just an experience of one person and one prototype

I had the same issue... What fixed it is: 1. I found that the screen protector was hindering it somewhat. 2. Go to settings->display->screen-off effect-> and change it to simple. This REALLY seemed to help. Let us know!

I did notice it does seem to behave better when set to simple for the screen off animation.
My screen protector does have a cutout around the sensors. Keeping the sensor area clean enough to qualify as having OCD does seem to make it work properly the first time, every time. Maybe it's overly sensitive?
Edit: Scratch that. 30 seconds later it's behaving erratically again. Maybe it's not the fact that it's clean, but the swiping over the sensor that temporarily resolves it.

it also seems to work much better when knocking at the top of the screen where the statusbar would be.

So I ended up swapping the phone out over the weekend for a new one and now everything seems to work just fine. Seems to indicate that it's not a software problem, but rather a hardware issue with the proximity sensor.

Guys if your covering the sensors when turing the device screen on it will turn right back of on you. It's a feature LG implemented so the device wouldnt wake up in your pockets. Don't cover the sensors.
Need a little example? Grab your phone and cover the sensors and knock knock knock.You can knock till the cows come home but it will not turn on. Same thing goes for the power button but its a little delayed and will turn the screen on for half a sec and turn right back off. Practice not to do this because your phone isn't broken. There is actually a thread on this deep in the forums somewhere but its been forgotten now.

This is true however there are indications of problems with the proximity sensor as well. Some of the devices are behaving as if tree sensor is covered even when it's not.

Thanks for this.. Very insightful.. I tried it immediately LOL

I had the same issue. I have no case or screen protector on, and was not covering the sensor when trying to wake the phone. For some reason though, knocking wouldn't wake the phone, and pressing the power button would only turn the screen on for a few seconds. I want even given enough time to get past the unlock screen. I went into the store and they are sending me a replacement that should come in later this week. It doesn't happen all the time. It is much more noticeable after receiving a call though.

Definitely is dependent on the proximity sensor. If i just have my thumb on the edge of the phone by the sensor it will display this problem. Even with my finger a half to one inch above it will do this. I will be paying close attention to the proximity sensor from now on when it doesn't work. Still have a few days to return and thought i had an issue but maybe not.

sometimes its also greasy fingers, at least in my case, rarely though

As long as you tap twice the same place it's working fine. If distance between first and second tap is greater than 1 - 1.5 cm it won't work.

Got the same problem on my d802...when i left the phone on my table for 2-3min it wont wake up on first knock knock even power key wake it up for 1sec after auto turn off again....even with no screen protector....i noticed that sometimes there is a delay about 5-10sec after knock knock and screen turns on....other thing i noticed when i knock on immediently after turning off it works 100%....BUT i also noticed when i knock on after a while it turns on and i can unlock got vibration and sound of the unlock but i cant see anything. Screen looks like its off but when i look closely i can hardly see widgets and when i set effect to tv out i can see the effect by pressing the power button...when i press the power button again screen turns on like normal...i noticed sometimes on a rerboot the lg bootlogo disapears the led is working an showing all colors but the boot animation is gone like the screen is off at the bootup...dont know why after the bootup the pin lock screen is showing up normal....sorry for my english^^

Disable automatic screen shutoff during phone calls

I have a crack in my screen which seems to make the phone's sensor think it's constantly pressed against my ear, thus not allowing me to use the keypad during calls, switch apps during calls, and on incoming calls, not even hang up.
I was wondering if anyone knew of any way to disable the automatic screen shutoff so I can get around this. I am using CyanogenMod 10.2 on a rooted Sprint galaxy s4, but have had the same problem with the derrick Samsung os.
Thank you, and if I'm posting this in the wrong place, apologies and please let me know where it belongs!

The screen off during calls is controlled by 1 of the top sensors, not by screen touch...Maybe there is damage to or on the surface area above the sensor...

I know you're on CM but here's how it's done in stock, you can toggle the "Turn off screen during calls" when you bring up the dial pad and hit menu then call settings.
Unselecting that item keeps the screen on as it won't use the proximity settings (like when you put it to your ear) to turn off the screen...which is essentially what you've already described that you think is occurring with the crack in your screen...
hope that helps.

Never noticed that, thanks! I wasn't able to find something similar in my OS. I love CM, but I might have to switch back to stock for this.

Btw I also noticed it's accessible through settings > my device > call in stock.
Anyhow, instead of moving from CM, have you tried something like this app to turn off the sensor in calls https://play.google.com/store/apps/details?id=com.itsme4ucz.screenoff
or tried to use the Tasker app to toggle it off? might be worth a shot.
EDIT:
There was a mod for this, so you're likely to find something around that will coincide with what your running on yours - see this: http://www.modaco.com/topic/362514-mod-disable-proximity-sensor-cm101-based-roms-only/
also have you seen this thread on issues with this in CM http://forum.xda-developers.com/showthread.php?t=2409698 ?
AND the other option is to try blowing air in might help, just in case it isn't related to your screen crack....see also: http://forums.androidcentral.com/sa...edition/311795-s4-proximity-sensor-issue.html

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.
