Hi all, I absolutely love the HD2. However, I find one really annoying problem about the "auto LCD shut off between dialing and after a call is connected, and this has been really driving me crazy! I'm not sure why no one has mentioned about this, is it because it is my problem of mis-using it or no one has bothered to voice it up?? I apologized if this has been posted but I couldn't find one solution so far.
It is about the auto LCD shut off sensor feature while making a call. My English is not that good, my mother tongue is Chinese, I will try my best to describe the problem written in English. I've tried so many cooked roms, all have the same old frustrating issue. After when I've dialed a number, as most ppl do, I will put the phone near my ear while waiting for the call to get connected. However, in the process while making the call while the phone is near my ear, the LCD will shut off by itself, and when a call is connected, the annoying issue will occur! When a call is connected, the LCD will turn back on by itself even though the phone is still in tack with the ear, as a result, part of our face will make contact on the screen and very often pressing one of the on-screen buttons! Also, it is not only this problem will happen after a call is connected, during a process of calling or during a conversation, if there is a notification prompted out, for example, a sms have been received, or a email has been received or low battery notification, the LCD will always turn back on and make the face accidentally press on one of the on-screen button, this is really annoying, is there a solution to let the sensor shut off the LCD for good until the phone has really get away from the ear and the face???
It's not a problem
It's an advantage
HTC did that to prevent you from touching anything with your ear and you cheek and maybe without this you could end the call accidentally or lunching apps so and so .....
Some people have found that this happens when their screen protector is too close or covering the sensor. Cutting away a small ammount of the screen protector to make sure it doesn't interfere with the sensor seems to be the answer.
Not sure you have read his question correctly - it turns off when he puts it to his head, which he wants, but then it turns back on again when the call connects.
I have the same problem, (incidentally had the same problem with a Diamond and Omnia II with Tachi phone canvas). Only solution was to breifly move it away from your head and back again, which I just got used to.
No idea how to solve it though. Sorry.
[APP] Proximity Sensor for Screen Off v0.2
Maybe you should look for this little app, it could work for you.
I can't post links, so make a search inside xda, there's a topic with that title.....

thank you so much! I will look for it, and hope it is a solution.
I have a problem with my HD 2 thats annoying. When i make phone calls, my cheek is constantly touching the screen which makes the phone beep so bad the caller can't hear me. I tried the sensitivity cab and it didn't help. I installed a screen protector and it didn't help. I thought there was a proximity sensor to keep this from happening. I searched and couldn't find a solution. I have to change phones if I'm expecting an important call right now. This is very disappointing for an 850.00 phone.
the phone should go to "sleep" so to speak when you place it to your cheek if your speaking to someone.
Im assuming this doesnt happen for you?
The screen goes dark, but, my cheek still activates it. DiD I miss a setting or something?
i cant say i've notice this problem myself, and ive not made any changed to settings. Sorry i cant be anymore help, im sure theres someone who can shed some light on this
Thanks for trying.
One annoying problem is also having threads whitout a clear title except for "I have some problem"
j/k
If your screen does go off then it means your proximity sensor is working. While it's off it's also unsensitive to the touch.
If instead you hear keypad tones sounds from your cheek contact, it means that it is being activated because you somehow moved your ear away from the sensor, check the display, it should be lit.
Happens to me as well from time to time, I just have to move the phone to my ear better so the sensor goes off and the problem is solved
No cookies for you, grumpy! Hahahaha! I didn't know about the moving thing. I'll try that next call. Thanks.
Took off screen protector, made a call, and purposely pressed my face onto the screen and no presses.....hmmmmm.
I've in my htc hd2 the Dutty FAM v6 HD2 rom, and I was trying an Android build (mjdejay Clean 2.2)...
It seems everything runs ok, but I've done a Phone Call, screen automatically got black (Off, like in WM 6.5), but when i finished the call, i cannot get screen on again... I've pressed all the buttons, but nothing appears to happen...
If i plug usb wire into HD2 it comes back, and if i do an incoming call, i can take it...
Nobody has got samething? Thnx!
UPDATE: I think that my HTC HD2 has its proximity sensor broken...
A number of members have the same issue. I do. But not always. No fix for the moment.
move the fone away from ur ear
also , get a better rom (even tho i have a mdj build myself)

Gee at least you didn't say buy an android phone. To say take it away from your ear is redundant. And to try a better build is just as bad. Why did you even waste your time replying?

this happened on my phone occasionally (though i haven't experienced it yet with mdj s4 kenel), anyways...
if the screen stayed black after moving the phone away from my ear, id cover the light sensor briefly with a thumb (or whatever!) BEFORE pressing the end call button, this always restored the screen. may work for you?
Hi. I have same problem. Now I have MDJ Froyo Sense 2.4. It is very frustrating all roms what i tested has this problem... Is any solution? I tried to disable automatic display brightnes but without success...
Just to make you feel you are in company I have this issue too. It is the single biggest pain in the ass about android and it isdriving me maaaad.
Still better than rocking WM though.
Same problem here, about 90% of the time. It's most annoying when you're on some automated service that asks you to press a number and you can't get your screen on to bring up the dialpad!
Rest assured though, pressing the end call button does indeed end the call. Just leave the phone alone for a minute or so afterwards and it appears to back to "normal".
Finally i have found a workaround
Hello, after many tests i have found good workaround. It is very simple. Download from Market: "Speaker Shake" (there is avaible a free version) and install it. Then set it like on my screenshot. (important setting is "Speaker Always ON"). Now when you start a call, this app automaticly turn on speaker - this event wake up your phone and then is end of your "black screen". After this you can again switch off speaker in time of call...
Sorry for my bad english. I hope that it will help to you..
I use MDJ FroYo Sense Clean v. 2.4 [kernel: MDJ S6.1]
Thanks. I will give Speaker Shake a try.
Just a little happier right now as others have this issue and that it is just not an issue with my phone.
I am sure it is just an incompatible driver somewhere. Never noticed it in prior builds but with new builds it happens. But not always. But I did notice if I am able to select speaker then turn speaker off the issue doesn't happen. But then the screen does not go black when I put it to my ear.
To me this is a much bigger issue than data freezes. Makes using my phone as a phone almost unbearable.
Hoping someone who knows how will look into this issue soon.
Tried Speaker Shake.
Calls are automatically with speaker on and screen stays awake. However after turning speaker off the screen goes black and won't turn on again.
Nice fix if using speaker ALWAYS but still doesn't help for normal calls.
I tried it many times and this issue "after turning speaker off the screen goes black and won't turn on again" i had only once.
I have changed this app and now it turns speaker back to normal. You can try it. For my is it now best solution how to avoid black screen....
And i forgot to say that you need to have switched off automatic brightness of display..
Has anyone tried covering the light sensors for a few secs?
Not the best solution but it always works for me, can live with that till it gets sorted.

It doesn't work for me...
Hello. I have a problem with unlocking the phone. When I lock the phone and try it again to unlock the screen lights up only in black. Sometimes it takes a second, sometimes longer. You have the same problem? Any fix?
Thanks petapen. I will try your modified application.
Still wondering what the issue is here. Newer kernal issue? I believe I am still running hastarin 8.3.
Edit: And for other poster.......covering light sensor or exposing it to bright light does nothing once it turns black.
If anyone have any another solution. Please let me know....
black screen

Screebl.....
If you haven't disabled auto brightness, do that. Secondly, some roms require a person to press the "call" key to wake the phone up.
Lastly, try a different rom, just remember to shut off auto brightness. I wish they came with that defaulted to off anyway.
Bumping this thread to keep it alive. Had a 50% chance of keeping the screen on, in froyostone v3.1. But it always came back after hitting end call key.
With MDJ FroYo HD v.4.3 the screen goes black everytime. Even after call the screen does not come back on. Only work around is to have someone call my phone and reject the call with the call end key. Then the screen turns back on.
Still tested different NAND-Android Roms on my HD2 but got still a problem. If i make a phone call and the screen turns black while calling i press the endkey to end the phone call. But instead of turning on the device, the screen stays black and i need to pull the battery and restart the phone.
If i make a phone call and use the free speaking funktion, while the screen don't turn off, i got no problem when ending the phone call.
I don't know what the problem could be, but it seems, that the thing has to do with the sensor who turns the screen on and off. But i don't know if this is the problem and/or know how to fix this problem. Like i said, i tested different Android Roms formated the SD-Card, deleted cache and all the stuff, but nothing fixed this problem. :-(
28 Views and no one with this problem? :-(
There are 2 other threads discussing this issue already. Here is one.
http://forum.xda-developers.com/showthread.php?t=946012
Issue lies with the light/proximity sensor. Could be defective hardware. Could be incorrect sensor drivers. Could be dirty sensors. I have yet to take mine apart to check for dirt on sensors. Blowing into the led/earpiece opening seemed to help. I notice if it doesn't come back on I can hold a very bright light (ex: cigarette lighter) about an inch away and the screen comes on as long as the lighter is lit. Sometimes it stays on.
thanks for your answer. seems to be more things to test and maybe solve this problem. Thanks!
THANK YOU Agoattamer!
Your link helped me to solve the problem! I just cutted a little piece of my screen protector, where the proximity sensor is, and got no more freezes after the phone calls! The screen protector still got two holes for the light and proximity sensor, but this seemed not to be big enough. Anyway, thank you a lot for your post!

I also tried a a lot of different NAND ROM and I had also this problem and I can't use Android efficiently. Now I am using hyperdroid ROM ( first GBX now CM). With this ROM and sanity app (from market, with correct settings you can find with trying) I almost solve this problem. ( probability of 95 % I don't get this error)
hey guys! i found the solution goin through the market!
download an app called "Sanity" theres a free version in the regular android market.
go to the settings > general > check "Reverse Proximity" (This will give you some warning about not using it if you DONT have a buggy proximity sensor). Check it anyways. Then go back to preferences then click "Proximity" scroll down and uncheck Turn off screen and leave leave the Turn on screen checked. this will force your phone to stay on during calls so that it never has to go through the proximity phase of calls this no more black screens. Hope this was helpful ^_^

Does any other one tried this solution ???
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.
