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

Q) Is it possible to disable home button to activate the screen?

After the Mango Update my Optimus 7 wakes up everytime i press the home button. This also happens in my pocket or phonesleeve because the button sticks out. So the screen is all day long on and drains battery like hell....
Is it possible by, for example, a register hack to disable this? so that my screen stays of and only be activated by the button on top.... and saves my battery?

I would like to know this also....
Anybody??

My phone never activated in my pocket because this button controlled by the light sensor

You're right.... 8-0
I never noticed this, because when I get the phone out of my pocket it is always on (I inadvertently press this button when getting it out of my pocket). As I understand now it is switching on at that moment... I want to switch off this button because of the spontaneous rebooting problem of the phone. This was introduced on my phone after updating to mango (7720). I must say, since updating to 8107 this has not reoccurred.
As long as this problem does not reoccur I don't really need to switch off the windows button as a 'on' switch.

Mine doesnt reboot on itself. But it eats battery as i wear it in my pocket all day.... and that sucks...

You may try to put your finger on the light sensor and try to press the home button .If this activate the phone is wrong .

Cool dude,.... didnt know that! it works as it should be. When i cover the sensor en press the home button the screen stays "of". I will try and find out if this helps when its in the phonepouch or pocket....
Maybe when i dissable the sensor in settings, that will help to...
Keep u posted

That doesn't work

Windows button not always responding?

Hello! Just bought an Optimus 7! Really good phone for the price!
But i got one problem! When im going to turn on the phone with the windows button its sometimes not responding!
Somebody else got this problem?

Yes. Happens to me all the time, but I always use the power button to turn on the screen so it doesn't bother me that much...

Sounds like a known issue.

Same here. It must be a software bug because the button is always working when the phone is unlocked.

If you still hold for a while it works

One reason for the screen not turning on is that you may be blocking the proximity sensor at the top left of the phone. The reason behind that is probably to avoid turning on the screen when the phone is e.g. in a pocket.

for me the start button for screen unlock always works, but many times screen is unlocked and all black, the systems listen to the touch input but doesnt show nothing at all....it happens very often usually when the phone is hot...

Does your touchscreen even work? If not, then you probably got a faulty one.

yep

Ohh, but that's not the lockscreen.
That's the S-view cover screen.
@DeepankarS knows more about how to solve it.

@Lennyz1988 thank you
@sikboarder Try removing the L1 screw and starting the phone again. Or keep a magnet near you, when this appears, touch the magnet (not a strong one) neat the volume keys and remove it. When this disappears, force stop sec.android.sviewcover from the application manager.
Still if it does not help, try an AOSP rom. Touchwiz has this stupid bug.

Nexus Screen turns off and refusing to turn back on.

Hey everyone,
I got a nexus 2 days ago and I love the phone! But theres this annoying problem when the screen is off. When I come to turn it on by the power button it wont turn on at all I know the phone is running but whenever i press the button to turn the screen on it wont come on at all I have to keep pressing the power button numerous of times to get it working and I can feel the phone vibrating when i keep pressing the power button so I obviously know that the phone is working not shut down. Is there anyway to fix that because its quite annoying I got the phone just recently and there hasn't been any problems with it everything works great its just THAT problem I want to resolve.
Oh yeah this issue only occurs at random moments.
Thanks!

Try setting the fingerprint screen lock and see if scanning your fingerprint turns on the screen as a by pass. Not sure what could cause such issue hopefully just some faulty software.

It turns out it was a display problem. I returned the device back to the people who i bought it from and waiting to get a replacement.
