Screen Lock issue with HD2

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.

Same for me

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

Screen turns off/on in call?

I got a question. When you're talking on the phone, does your screen goes off in 10 seconds, then 2 seconds later, the screen turns back on, then turns off in 10 seconds, and keeps going..
Cuz while I was talking on the phone using bluetooth, I just happen to noticed this and even using my finger to hide the proximity sensor, it does the same thing.
[EDIT] When I'm on a call and then hit the home button to get to the main screen (still on call), then it turns off like normal and it won't turn itself on. But for some reason, in the "Call Window" it just repeatedly goes off and on.. Hmmm
Problem 2: When I'm on a call, and have my phone in my pocket, when someone phones me, my leg would help me 'accept' the call. I did a test. When I'm on a call and block the proximity sensor, the screen locks up (which is fine) but when someone phones in (call waiting), the screen is accessible again even though the proximity server is still covered. This makes it so that it would still accidently accept the call when someone phones in while still in pocket.
Can anyone try it and see if it does it on your phone?

Yes mine does that. It sucks because frequently, I will hit the hang up button with my cheek. Annoying.

I hope they fix this asap...
its very annoying, mine does the same thing

Screen blank on power on

I've had a problem with my E900 since I got it with regards to the screen. I was hoping Mango might fix it but it doesn't seem to have.
Sometimes if I press the power button the screen backlight comes on (i.e. screen goes from off state to powered) but there is nothing on the screen. No amount of button pressing will cause the screen to show anything.
If this happens I have to turn the device off again (backlight then goes off) and try again. Sometimes it can take 2-3 times before it turns on successfully with the lock screen.
I also have this if an incoming call attempts to wake the phone and also alarms too.
Does anyone else have this issue?

I confirm this one popping sometimes. Not that often that it becomes annoying, but nevertheless.

Did you find a solution to this problem? I am experiencing it too and it is very annoying!

I've recently inherited one as well (E900 that is).
The one I have has been dropped, the backlight powers, but no drawing on the screen.
I've disassembled and re plugged everything (bugger stripping down!) but still no luck. I've done a VolUp+Down+Cam+power hard reset, and when I plug into PC Zune says setup needs completing (so it has reformatted) but still no luck.
I cant see anything fried, and no damaged ribbons as far as I can see, any ideas?

I sold the phone a while ago, and never solved the problem. I think it's a firmware issue.

hi.
What do you mean "somethimes if I press power button"?
Is it pressed with purpose to lock the phone, press it to turn off phone (background slider shows to power off - on Mango and beyond version) or press it accidentally?
Cheers.

So, I did a phone reset. Unfortunately the issue is still present!
Sometimes when I press the power button to unlock the phone the screen is lit, but stays blank i.e. no lockscreen wallpaper, no nothing. The same happens sometimes when I get a phone call - the phone rings and vibrates, the screen is lit but stays blank.
When this happens I have to press the power button to put the phone into sleep mode and press it again to wake it up.
What I found is, when the issue occurs the screen is actually responsive. For example I can slid up and unlock the phone then I hear the unlock "pop" sound. It's just that nothing is drawn on it!
I was wondering if anyone else experienced the same behavior and found a resolution. Also I am not sure if this is a software or a hardware problem. If I could confirm it was a hardware problem I would call LG and have the phone repaired or replaced.

i have exactly the same issue as you, it gets really annoying.
i heard from someone online that the only way to resolve it is to replace the motherboard

I am pretty certain this is a hardware issue. I am calling LG tomorrow and hopefully they'll take the phone for repair/replacement.

I sent my phone for repair. Today I got it back, and guess what?!
The issue is still present! It seems, they "couldn't reproduce" or something.
What should I do now?
EDIT: If anyone is interested, here is a video I just captured which clearly demonstrates the problem. http://youtu.be/38kF9RYs_bU
I'm sending the phone back for repair tomorrow with this video attached.

Hey, might not be an issue at all, but in the video, I saw that the two times you were able to get it to go blank you had your finger on or near the proximity sensor. I wonder if there is something that could be the trigger.
Just wondering if you can duplicated it or cause it only when you have the proximity sensor blocked, or if it truely is random.

You are right, it might has something to do with the proximity/light sensor.
On the other hand, this issue occurs even on incoming calls when the phone is placed on a table, screen up and nothing around the sensor.
Today, I visited my local carrier shop and left the phone for repair again. They told me, since this is a second claim they'll run it through the process faster, so I expect to get it back next week.
Will post an update.
UPDATE: My phone was replaced. Yesterday I got a brand new unit, yeah! It was stock wp 7.0. I plugged in my sim and used the phone the whole day, no sign of blank screen issues. Last nigh I installed all the updates (total 5 I think) up to OS 7.10.8107.79, FW 1.0.16.10. Guess what?! Same issue!
I am crushed

Pattern Lock When On Calls

Hi guys
Had a search and nobody else seems to be having this problem, but seems so basic that I'm sure I must be missing something obvious!
When I'm in a call (either incoming or outgoing) I can't get the screen to turn on properly in order to hang up or use other programs (check calendar etc). This is particularly annoying on outgoing calls as it makes hanging up very difficult!
To be more detailed, a single tap on the power button has no effect on the screen - it stays off. If I repeatedly click the power button, sometimes the screen will flash on for a miniscule moment - this is my hang up method at the moment, repeatedly press the power button and tap the screen near where the hang up icon will be, and eventually I'll catch it while the screen's on. Once I'm off a call, things act as normal.
I have Pattern Lock set up, and am prompted to unlock the phone once I'm off a call, this is what I'd expect from previous Android phones but might be causing problems here?
I found this previous thread where people have had very similar symptoms because their screen protector is over the proximity sensor, but I don't have a screen protector. Might I have a dodgy proximity sensor? Is there any way of testing it?
Cheers for the help!

I have the same problem. It doesn't happen all the time, naturally, but it's been frequent enough to be irritating. If anyone figures this out, I'd love to hear a solution.

Frustratingly this does seem to happen to me every time - although it might only be once the timeout has activated the pattern lock. Or I could be barking up the wrong tree entirely!
Think I might have to do some testing tonight . . .

After some fiddling it does seem that it's a problem with the proximity sensor - Elixir 2's settings show the proximity sensor always showing "near"
If someone could run Elixir 2 on their N4 and confirm that they do get changing settings, it would be a great help!

Delay problems

Hi everyone!
After i rooted and flashed a recovery on my note 3 realized that whenever i reboot or shut down and power on my phone after i unlock the sim (via pin) the phone gets at home screen but is like dead, meaning for about a minute or two i cant lock the screen with the power button, the home and settings buttons dont light up when i push them or do any noise or vibration, wifi remains off, power saving remains off until the phone makes a quick vibe after 2 minutes or so. That quick vibe was quicker before the root and recovery, it was instant after i unlocked the sim. Also after that problem i got a calling delay, after i try to call someone now and then i have to wait for a minute or so until the call starts. The screen stays at dial pad but doesnt do anything, i can dial numbers but no key noise no key vibration. I unrooted my phone, flashed the stock rom again etc but the problem remains. If anyone knows what to do please help me out

I've not done anything to the system at all (Root, flash etc, I'm on full stock) and mine does this too. I boot it up, and for a ful 2-3 minutes it simply remains on and I can't do anything to get it to turn off. I can long-press the power key to bring up the menu, but locking the screen is simply not happening at all. Irritating, but alas.
As for the delay in calling, it usually takes a while between the dialing out and the line to actualy establish, that's probably a network issue.

i don't think that its a network problem because it happens only to me and not always. It takes a while normally but in my case it stuck's on the dial pad not between dial and line. It doesn't even turn the screen off if i put it to my ear...

Have you tried to disable the SIM pin?
I never have a pin code on my SIM and never seen this problem.
