HD2 Bug: No Standby mode, screen always on

Hello
My HD2 Worked well for a long time, but now everytime I press the "sleep" key it turns off for half a second then turns back on and proudly displays the lockscreen without me pressing anything. There is no way to turn the screen off and go in standby mode anymore.
Obviously the battery drains so much faster from not being able to have the screen off and this silly problem actually makes the phone unusable
I flashed a few roms using HardSPL and now HSPL2. I'm currently running Artemis 11.0, the problem appeared may days after flashing while using Artemis ROM 9.0. A hard reset seemed to fix it but the problem reappeared. Today flashing 11.0 only solved the problem at first boot.
Anyone had that before? Not sure if it's software/rom related or not anymore. HELP

As far as Ive seen, its only you an me who have had this problem so far.
Honestly, Im relieved to see someone else with this problem.
I had exactly as you described, but using Axlor roms.
It worked fine for 1/2months, then all of a suddon the screen backlight wouldnt go off, but a reset fixed it.
But it got worse and worse.
Now nothing will work...
Ive taken everything back to stock, and i mean EVERYTHING! Not a single app installed.
And I still have this problem. I've tried it all.
I think its a warrenty job....
EDIT:
I also noticed the backlight will go off fine when the phone is charging, is that the same for you?
I just sent the phone off to Tmob today, to see if they can fix/replace it.
I'll keep you informed.

Same problem. Was running fine on stock ROM 1.66 then backlight did not dim and would not go into standby. Put into standby, screen goes off then straight back on to the lock screen. Since then have had other problems at boot, sometimes it locks on HTC white screen needing battery removal, sometimes launches straight into Navipanel and will not exit, HTC sense homescreen sometimes launches in landscape and will not go into normal portrait mode. Reflashed with different ROM's same symptoms persist so have returned to Vodafone UK under warranty, fingers crossed.

i've had this on early versions of the rom i use, the chef fixed it, making me think its the software, not your phone.

I experienced this issue when I minimised a game called virtual pool. Closing it in task manager would then allow me to permanently make the phone sleep.

How come Ive still got the problem after reflashing several times and taking everything back to exactly as it came from the box?

I too have had the navi panel problem.
Im praying they fix mine under warrenty

Yes the problem is exactly what you describe, hard reset and flashing to a stock rom doesn t fix it with no programm running in the background
Navipanel seems to be on randomly sometimes so can I guess it could be related.
I found a fix, after starting the phone, plugging and unplugging the usb cable to the phone WHILE THE SCREEN IS ON fixes it but only until the next restart
Considering sending it for warranty now.
Thanks for replies! If anybody knows more let us know

Update re standby problem
Got my phone back from Vodafone UK today. Was advised software corrupted and that they had reflashed and it had been fully tested and was now working fine.
On power up (even without SD card or SIM) it had exactly the same fault as before, when put into sleep mode the screen comes back on after about 1 second.
I tried the plug in and remove USB lead fix and this also works for me until the next restart so it would seem that this must be a hardware problem.

What other options do with have if they sent it back without fixing it?

Ive noticed allot more people getting this problem. So its not only us.
Tmob are replacing mine, so Im guessing its out of our control now.

did any of you guys try performing a task 29 in between flashing roms? it may help

Actually no, I overlooked it.
Probably would have been a good idea
Prehaps thats worth a try Mr Opr

Thanks for this workaround. Now with the urgency gone hopefully somebody finds a lasting solution without the need of sending it in..

I have same problem guys after 4 months using. ...and my HD2 is unusable with no standby. I mean battery gets weak during 2-3 hours. Whats your guess guys is it software problem. Cause Im afraid of this is hardware prob because after reset goes my device in wrong state.
Help!

Sadly I'm running into this same error with my t-mobile hd2....getting serious power drain...can anyone confirm if the task 29 helped at all? Mine won't stay off for more than 30 seconds.
** Found out the google easy sms beta app I was running had a service which was causing the app to come out of standby...uninstalling this app cured the problem.

For me, it was a sd slot problem. When i removed the sd card, phone always waked up after 0.5 seconds, and card was detected as bad.
Now the SD slot was changed (under guarranty) and it work fine, no wake up if sd slot is empty.

Any update on this? My HD2 starting doing this today as well
And I have no usb cable at work to 'trick' it. The only option is to pull the battery which I don't want to do. This is ridiculous. Am I going to have to hard-reset the damn thing to fix it?
FYI I didn't do *ANYTHING* to my phone in a couple of weeks (no new apps, etc.) and it started doing this out of the blue.
You hit the red 'end call' button and it goes black..then comes right back on.
The odd thing is it *thinks* its plugged in because the only screen setting I can get it to acknoweldge is the 'backlight level when charging'. So somehow my phone thinks its plugged in even though my only usb cable is back home.
Grrr. No registry tweaks or temp files I can delete to reset this behavior?

[Q] Screen problems when waking up

I have a problem with my screen:
when i press the power button to wake the screen, it lights up and then blacks down again, it doesn't matter how i press the button (how long i press and so on).
it happens sometimes, sometimes not, but happens more frequent than NOT happening so it's quite enervating.. usually i have to try to light up the screen 2 or 3 times before it works..
This problem i had before i flashed to a new rom too, but i didn't do a wipe when flashing so can this be a problem from software or does it seem to be hardware?

Screen wake issues or the screen on/off animations are known issues. If your flashing a different rom its always recommended you do a full wipe. That in itself could solve your problem. Also posting the rom your using and the settings (if you have it over clocked) would be very helpfull when posting a problem your having. If you disable the screen animations it will work fine. If you like the animations and have your phone overclocked you may want to try adjusting that also. There are several post on screen wake issues that could possibly help you in this forum.

go for a wipe and fresh reinstall of the rom always works for me when i have problems

You can also try turning off automatic Brightness . it worked for me

I have tried all of your tips except for a clean install, nothing of it worked.
i try to avoid a clean install since i am really satisfied with my homescreen layout and all my apps i have now

A wipe is recommened for a reason. It avoids threads like this being put up. You can't complain about something not working correctly if you haven't even followed the install instructions.

I use 5 minutes to set up my phone minutes after a clean installation. use titanium and bookmarkSB to backup your stuff.

Does your screen flash when you turn it off?

When I hit the power button to shut the screen off, it flashes brightly before it goes off.
Wondering if this is a Nook Color thing in general, or just a CM7 thing. Is this related to the fact that the screen animation doesn't work on CM7 when using the current kernel? I heard that Dalingrin had the screen animation working in the early test kernel and wondered if this got rid of the screen flash as well.

FWIW, mine flashes also. I haven't researched the cause, though.

CM7.0.2 from SD, when I tap the power button, it fades over about half a second. No flash, although occasionally there's a flicker in the middle of the fade. Power on happens much quicker, but there is a bit of fade-in.
I did enable on and off animations, even though I didn't think they were supposed to work yet.

this is a CM7 thing. its a power off and on animation. if you dont like it you can turn it off in settings. personally i like it. it reminds me of the old CRT screens.

More specifically it's a 2.3 thing - but I think the problem is that it doesn't work the same as on other standard resolution screens so it just ends up 'flashing' rather than doing a fancy animation. Your solution is correct though.

Interesting. The on/off animations are off by default in the Encore build. I enabled them in the settings and still had the flash (as one would expect). However, once I disabled them again everything was fine. I wonder if this is another persistence bug, similar to airplane mode?

My screen flashes whether the screen animations are on or off, though to be fair it doesn't flash every time, definitely more often than not though.

Mine is more of a quick blink rather than an obvious flash. And it isn't consistent.

My screen flashes as well. It just started doing this yesterday and I've been running cm7 off my sd card for about a week with no other problems. Worse, sometimes the screen turns green and stays that way until I hit the N button. Any idea what this means and possibly how to fix it? Any input would be greatly appreciated. Thanks.

Which version of CM7 are you running? I haven't seen the flash or the green screen since I switched from 7.0.2 to nightly 86. Maybe it's coincidence, but it looks like the flash issue has been fixed.
(The power button does sometimes turn off the screen briefly then turn it right back on again -- hitting the power button a second time always turns it off.)

It's the CM7.0.3 stable version. Maybe I should do an update. I wasn't sure if that was the problem since it had just started doing this. Are you saying you've seen the green screen? Just curious because I can't find anything about it anywhere. Thank you for your response. I'm going to try out the nightly and see if that fixes the problem.

Mine does more of a quick flicker,i think its the screen off/on animation issue on the nook because the animation works fine on my droid incredible cm7

Actually, that's what mine does too. Sometimes there's a flash, but most of the time it's a quick flicker. If it's just the animation then I probably don't need to worry about it. It's just the green screen that worried me...though that only occurred when I kept messing with it. I haven't messed with it the past couple of days so I haven't seen the green screen. Maybe I was causing some kind of error.

Yup, I've seen the green screen. I don't remember what build I was on at the time because I looked at a bunch over a couple of days. It could have been 7.0.3.
Or maybe I messed up something on my nook, and flashing another build corrected it? Either way, I haven't seen it in a few weeks.

That's good that you haven't seen it in a while. And not that I want anyone else to suffer, but I'm glad I wasn't the only one. LOL. Hopefully that means I'll have an easy fix. I haven't seen it in a few days myself, so I'm just going to wait and see what happens. Most likely I'll update to a nightly. Thanks for the responses. Now I'm not worried about it anymore.

Locks up on Resume from Hibernate (When power button is pressed)

I just bought a A7+ and it will not always return from a black screen. I can resume it a couple times after it has gone into a hibernation mode, then it will just randomly not work. The green light will stay solid and I can't see anything on the screen and the buttons will not work.
I tried flashing with the lastest firmware, which installed perfectly. However this still doesn't fix the problem.
It's incredabily annoying, to be reading a web page, set the tablet down, try to turn it on and in the process lock it up.
Any ideas? Am I doing something ridiculous here?

You are not the only one that has this problem. I have two that do the same thing. Did you ever find a solution?

If you go to the manufactures site and download the newest update it will fix this problem. You won't be able to use custom roms, but it will make it work

HELP little red sensor(?) always on next to front camera idk why

Hello all!
Yesterday I was 9gagging in my bed, and I noticed that little led started constantly lighting. Tried 2-3x to reboot but nothing happened, after the startup it started to light again... https://imgur.com/a/m4FK9lC You can see it in the picture.
Other question:
My screen rotation is also bugged. Tried to fix that with those reboots, but again nothing happened. I can not rotate my phone. (Only youtube fullscreen rotates the image, anything else stays horizontal)
Maybe its time for a ROM? The system starting to fall apart, had numerous random reboots etc. But I am afraid that with the ROM, a I will have a lot of other problems, like bluetooth and wifi not working together, camera is gonna be ****ty without LG's app.
What should i do?

That is the proximity sensor, and it is a normal behavior, otherwise it couldn't do its job

Yeah i know, but it should not light 24/7 and it did not light 24/7 before. Its a weird bug. And its really annoying... Especially at night...

Have you tried factory reset? Ib know it's the easy answer but I think it's the best in your case.
Anyway, it seems like a hardware issue, so if it persists after factory reset, I would send the phone to repair (i hope is still under warranty)

Yes it does. It turns off AOD in your pocket, raise-to-pick-up, screen off when in call.
There are a lot of actions connected to this sensor.
Btw, mine is also on all the time.

Just tried factory reset now for the rotation bug, it looks like I somehow totally broke it. I used pixel live wallpapers, especially the Zion national park one which used the accelerometer constantly. Tried a numerous kind of calibration apps, and all of them failed.
Totally hopeless now, i have to use a ****ty app to rotate my screen every time :/
