Anyone know how to prevent auto-locking/standby when talking on the phone?
The screen turns off when I'm talking, which I assume is from the light sensor, which is fine, but when I take the handset away from my ear it remains dark or is on lock.

I have the same problem since it was new. Sent it back for repair, and told nothing was wrong with it.
I uninstalled all my apps, but no improvement. shaking and tapping the phone makes the screen flash back on for half a second, but not long enough to press hang up or any keyboard numbers for automated answering systems.
I rooted the phone to see if I could get more control, but haven't found an answer yet.
first, where are you having this problem?
WinMo/Android
and second, it's not the light sensor, it's the proximity sensor.

Weird.
Was just on a call but had to search through my contacts and the screen would dim out every 1 second..press the back key again too continue looking and the screen dims out again.
Any ideas on why I can't run another task while on a call because the screen keeps dimming out?
the phone has a proximity sensor like the iphone. when on a call screen will automatically turn off when you put it up to your face because the sensor sees that theres no light (unless your face is a flashlight). you probably blocked it by accident while using the phone. its somewhere on the top of the phone dont kknow exactly where though.

Ahh that makes sense. My DSLR has that as well. Thanks for clearing that up.
Yeah if you put it on speaker it wont do it.
I'm having trouble with the proximity sensor on my HD2. It works if the phone is pressed up directly on my ear, but if I move it away just the slightest, the screen comes back. Is there somewhere I can access the proximity sensor settings, and give myself a bit more room? Like, say, anything inside an inch shuts off the screen?
ROM info is in the sig, and I'm using the HTC phone dialer, if that makes any difference.

Aw balls, I hate it when there's a thread for this, and my impatience with searching failed to find it.
Thanks!
Doesn't sound like that app does anything for the sensitivity, unless i missed it. it just makes the screen stay off after the sensor is activated.
However the point of the proximity sensor is to shut off the screen so your ear isn't pressing buttons. If you've got the phone far enough away from your ear to reactivate the screen, then there's no longer a need to turn off the screen to prevent ear dialing.
If you're worried about power savings, the screen should shutoff in a minute or so, depending on your screen timeout options

correct, I haven't found a way to change the sensitivity for it, just turn it on or off. I believe the way the sensor works like a motion sensor in a store, either you are there or not... Hardware driven on sensitivity, not software.

I actually posted about the sensor in another post. The sensor is just an IR LED and a photo diode. The photo diode looks for the reflected IR when the phone is near something like your ear.
The IR LED only turns on during a phone call. Try this get a digital camera with a live preview and aim it at the 2 dots where the proximity sensor is, you'll see the IR LED light up when you initiate a call
The same photo diode is used to alter the screen brightness depending on the ambient light that hits it
This might seem like a dumb question, and I just got my MTS 2 days ago, so I'm still learning about it, but at the top of the phone, where the LEDs are, what is the function of the opposite side of where you hear your calls? Is it there for looks or does it have LEDs in there also?
it is the proximity sensor... it is what "locks" the screen so you are not activating it with your cheek while on the phone... it also blacks out the screen when you are on the phone
I've always wondered what this was too... thanks for that information.
it also turns the button lights and keyboard lights on/off at certain light levels...that way when its bright it turns the lights off and when ur in the dark the lights come on...i love it!

that seems to be incorrect because i use the headset and if i lift the phone to a certain angle the phone screen turns off, but when i tilt it back down it turns on again. i will look into this more but from what i have seen it is just there to be a little more symmetrical(would you want a phone with asymmetrical looks to it)

no hes right it IS a proximity sensor...go where theres some light and open the keyboard and see if the keylights are on...if so, try to make it brighter...(shine a flashlight at it or something) and the lights will go off...then put your finger over the sensor and the lights will come on...it works, try it...definitely not just for decoration...what you are experiencing is a perfectly normal effect of the proximity sensor doing what it does...no reason to look into it...
or download "Sensor List" from the market and look, it lists the prox. sensor and its data...put your finger over it and watch the output jump...
or run adb logcat and put your finger over it and itll come up with a entry about the light value changing...

without the headset try calling your voice-mail in a lit room and hold the phone away from you and move it all around an at different angles, you will see it makes no changes but just by putting your thumb over that spot it kills the screen and as soon as you remove your thumb it comes back on... might want to actually do some reading or testing before saying someone is wrong. not only would a quick 5 second test show that it is the light/proximity sensor, or you could try a quick google search
You can also have the left light flash for missed messages.
i was doing some testing and i am retracting my statement, you were correct wulf and i am sorry that i doubted this.
hey it's kewl we all make mistakes
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.
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.
