When I'm on handsfree during a call and trying to access the phones menus or programs, the screen first lights up after pressing pwr button, stays on for about 0,5sec, then goes black, then flickers on again, then off, then on again, and then off!
Sometimes I manage to get it to stay on by pressing on the screen repeatedly during the first 0,5sec. But usually I go through that whole procedure and have to repeat it until I manage to access the phone.
Anyone experienced the same thing? Only happens during call.

Same thing here, I use a BT headset. It is quite annoying.. I think it is trying to shut down the screen, because of battery saving. But I want to use the phone while speaking
Could have to do with the proximity sensor maybe?
Yeah it is to do with the proximity sensor. To solve this issue I try not to hover my finger over the top of the phone where the speakers are located (I think this is where the proximity sensor is placed).

After i hang up on a call (when the phone is in sleep mode and the screen is locked) the screen unlocks. this is quite contrary to what is mentioned in the phone manual chapter 1 page 45. this becomes an issue since i use a bluetooth headset and the phone remains in its sleeve/case and after every call, a whole bunch of applications will launch since the case is in contact with the screen. have i overlooked some settings or are there other owners who have faced this issue?
ideas and suggestions welcomed
did you check it out if any of the hardware buttons being pressed against the case hence wakening up the phone.?
i had it to only closed al my apps in taskm and it stoped flickering
My HD2 is also behaving in the same way even in controlled test conditions - the phone unlocks when a call comes in (I'm presented with slide to accept or reject call) The phone unlocks during the call, but fails to lock again on disconnect (either by pressing "end call" or hang up via bluetooth).
Can anyone verify this? Is it interacting with something I installed?
I believe I found a (complicated) workaround.
What I want: leave HD2 inside pocket, answer calls with bluetooth headset, hang up and phone will go back to lock.
Problem: After I hang up using bluetooth or press the big red "End Call" button or the other party hangs up, the phone stays unlocked! It stays powered on and all kinds of buttons gets clicked.
Practically all lock sw uses their own lock screen (which I don't want to install). CSDevCtrl does not trigger by phone. TouchLockPro uses its own transparent lock screen but can respond to phone events. Using the !SUSPEND for TAPI\Ended under settings does not seem to work when the screen dims about 50 secs into the call.
Solution: Use TouchLockPro together with LockAndOff. Get TAPI\Ended to run LockAndOff will turn phone off, whether by bluetooth, big red "End Call" button, or the other party hangs up.
BTW: I think there is some confusion on whether the phone locks when you
1. press the big red "End Call" button, or
2. the hard "End call" button
in the forums.
I noticed that HD2 have a light sensor next to the top ear speaker.
During a call, if the phone is put near the ear and cover the light sensor , the screen become non-active which is good.
If anyone can come up with a lock sceen using this light sensor , then the problem with random launch of program when phone inside pocket will be solved.
This lock screen should only activated right after an end of call, beacuse , sometime you may want to use the phone in a dark place.

It's the proximity sensor that turns the screen on and off during a call, not the light sensor. How else would it work in the dark? (which it does)

My proximity sensor does not work, when I am getting a call my screen turn off and when I am taking the phone out from my face it turn on only when I am out side at the sun!! the screen stay off when I am inside room. I tested it with flsh light and it is working also.
I have a T-Mobile US version of the HD2. I am having the same problem when using the bluetooth system in my car. After answering or making a call the phone stay unlocked. And then starts making random calls while I am driving!!!!
There has got to be an easy fix for this!!!
Buy pocketshield, problem solved.
i have this unlock problem with 1.48 rom and i solve it by pressing start button and lock. after that everything works fine unless i change theme in settings. then just repeat first step.
Solved
Same trouble with me until I use the following software. I tried it and it's almost perfect. unzip it and just copy to your HD2, run CallerLoc.exe and click Yes, you'll find:when you hang up, or he/she hang up a call, or a call is established, the screen will turn off.
Why say 'almost perfect', the software is in chinese, but the filename is in english. and it's a call location software but with the function we need.
To stop or before you delete the software, run Callerloc.exe and click Yes again.
Hope this will help you. Sorry I don't find a English version of this software. I esure and I'm using this software perfectlly with my Leo.

Greetings.
I understand this is quite an old thread I'm digging up but I need a little help as well and I didn't want to start a new topic just for that.
I've this silly problem, appeared right out of the blue:
You all know the standard manila behavior, when the phone is idle, the screen first dims and after some more time, depending on your preferences, the screen locks. It also locks if you press the power off button. This all was happening to me till this morning.
I added an event in the calendar (the only change I made today) and after that, my phone dims and then goes in sleep mode after the designated period of time, but DOESN'T lock!!! It doesn't even lock when I press the power off button. I can still lock it by pressing Start and then lock or by press and hold the power button and choose the lock phone option. So one would say that it's still operational, so why bother about it, but I kinda liked the standard function and I have to freaking idea why it changed!!!
I'd be most appreciative if you could offer some help with that.
Oh, I forgot to mention. Soft reset didn't solve the problem. Erasing the calendar event didn't either.
My phone runs the factory ROM (1.66.482.1 ELL), I haven't changed anything other than user settings (yeah, I'm a noob... )
Thanks in advance!

Pocketshield could be the end of your problems. You can try it for 10 days and see how it goes...
But why do I need to buy third party software in order to revert my phone to it's original operation?
No, this is not the answer I am looking for. I was wondering if you know of any kind of settings that might have changed by accident and caused this undesired behavior.
Thanks.
The best to return to normal operation would be a hard reset. Or you can spend a while trying.
You can try
HKLM\Software\Microsoft\Shell\Lockscreen\Enable=1
HKLM\Software\Microsoft\Shell\Lockscreen\Active=1
Thank you very much. I opted for the hard reset option... I hope it stays ok this time!
My HD2 also had some strange unlocking and unwanted calling.
I noticed it appeared when using the android style lockscreen.
When I changed back to the original one, problem solved
i had this too. the andriod lockscreen seems to be a bit buggy last time i used it, i accidentially called 7 random numbers
Sometimes I need to get to the keyboard but the screen goes dark during calls sometimes. I dont know why it does that or what i am doing to cause this. It doesnt happen every time. Anyone know or can help?

The proximity sensor is supposed to blank the screen during a call. Try making a call with your phone on the table. Put your finger along the top of the front of the phone (where the speaker grill-area is located). Your screen should blank. When you take your finger away, it should wake up. If it doesn't wake up, try pressing the Talk/Send hardware button to wake up the phone.
I noticed this problem:
when i start a call, my screen become black and i cannot hang-up the call.
anyone with same problem?
another little question:
i have a time-limited data plan (40H /month) is there a way to know if my HD2/WP7 phone is connected or not? or a way to control my data connection?
thank you!
I have the same issue. If I hold the proximity sensor directly to a bright light source the screen comes back on but I'm not always near a bright light source. I've been making calls on my bluetooth headset because that has a hardware hang-up button. If someone could work out how to hook up the hd2 hang-up button this would be a massive help...
EDIT: i make some test, plese discard this post (test result in post #5)
I'm not sure about yours, but after I finish my call I just remove my phone from my ear then the screen show up . Regardless where I am (dim or bright place) the screen responds to the movement of the phone away from my ear .
ok, i make some other test.
confirmed, we have some problem with proximity sensors.
when i make a call, the screen become black. immediately, witoutn anything else.
wen i remove the phone from my ear the screen will NOT come up UNLESS the other part hang up.
for example: if the other part use an answering machine, i am able to record my message, but the screen DOES NOT comes up when i remove it from my ear.
if the other part is a friend, and HE hang up the call, my screens lights up, again, sayng "call ended". then return to the home screen.
if i'm in-call, and i expose the phone to a bright light, the screen comes back too, sowhing all in-call options (speaker activation keypad, and some other things)
Just press the normal hang up button and that should act as the power button to bring the screen back on...

during call this button doesn't do nothing.... already try with all button..
i just play with registry entries, some are interesting.
HKLM\Drivers\Builtin\Proximity
ScreenOffDebounceTime DWORD:50 (Decimal value)
ScreenOffThreshold DWORD:256 (Decimal value)
But i cannot figure how they affect screen (i try to change their value with no effect)
update:
seems i fix it!!!
after an UPGRADE (hehehe) to winMo 6.5, i realize that problem still exist.
then i remove a portion of the screen protextor and proximity sensors works again!
even if i use original HTC screen protector... :\

I've tried that already but it didn't work for me. I did have my screen replaced so I wonder if the problem started then...
Same to me... Is this a replaced screen issue?
Strange one this...the red button (bottom right of the 5 physical buttons) just brings the screen to life for me and should work I would have thought regardless if screen is replaced.
hey guys i am facing a problem too with my tmous hd2...i have dual booted it..when i make a call in android or win7 proximity sensor doesnt turn off the screen at all.....so i end calls without my knowledge and intent.....anyone facing similar issues??? anybody knows any solution???
i read that the problem could be the screen protector so i removed it. still the same problem. as soon as i start a call, the display goes dark and cant be reactivated until the call has ended. i already reseted the phone. didnt help anything.
is the sensor dead?
Have you tried turning the screen on after you pick up?
of course i did but it doesnt work. or it just flashes randomly very fast after pressing the power button multiple times.
Do you have a screen protector on there? I had a Realook screen protector on there for a day and it kept happening. It covers the sensor so after you start the call, it goes dark immediately. Thought it was hardware problem until I remembered it was working fine before I put on a screen protector.
i removed the screen protector, as i said in my first post.
That's a common problem, its due to a bug in the proximity sensor.
Try keeping it away from your face for a few seconds and than pressing the power button to turn it on, if that doesn't work, than there is no real fix that I am aware of.

well the thing is, i never put it near my face. i always hold it in my hand and dial/call.
It could also be a faulty proximity sensor. You can get apps the check the prox. sensor. See if they're picking it up correctly.
If it seems like it's not working, you could send it in for repair.
when you start a call the display is on and will turn off when you cover the top left, I enabled power button to hang up and it didn't come on when i moved it from my ear on a long call till I pressed the power button lol,
I will have to try with swipe to wake or another way to turn display on,
you rooted?
When i make a call, and place the phone on my ear, the screen will go black (turned off), but when i take it away from the ears, thr screen stays off. I had to press a button like power or volume to turn on the screen.
This wasn't a problem when i first got the phone (3 months ago).
Only recently i got the problem.
Phone is stock, not rooted and still on 4.4.4
I searched the settings, but couldn't find any.
I tried *#0*# to being up the hardware test, went to sensors, waved on the sensors, and i got green screen and the phone vibrated, so i assume the hardware is working fine.
I'm guessing this got to do with software?
Please help
Anyone?
Hey...so in the test where you cover the prox sensor and it turns green and vibrates, does it stop when you lift your finger and then able to repeat that?
If so the sensor should be fine, try a restart. Pull battery out or hold power button > restart phone. If you haven't already.
When i moved my hand over the sensor, it turned green and kept vibrating. Only way to stop it was to press back on the capacitive button.
I have restarted, took battery off etc. No luck.
Any other suggestions?

R u using any screen guard? If yes first try to clean that area or make sure it's not covering sensor.

I did, and I thought that too, so I remove the screen guard, and still the same.
I've cleaned the surface etc... :crying:
