I've just noticed my HD2 back light completely turns off ,and it is frequent.I can only weak up it by turning off and turning on again, I assume therer some problems with the light sensor? The backlight turns off is just like when you are talking on a phone and put your phone close to your ear. Aslo, when I plug it to charge via Ac power(via usb to PC is fine), the drak orange led light is always flashing which is abnormal.
I have tired a clean boot and unplug SIM card, micro sd card, the issue is still here, I guess I have got a hardware problem? I have used it very carefully, how come it has that issue?
Any fellows here have the same issues so far?
Thanks.

You can set up the backlighting behaviour as follows:
Go to: Settings tab > Sound & Display > Backlight
Find the entry "Dim Backlight if device is not used for"
Change the value to whichever duration suits you
You can set this up for when the device is unplugged or when it is on external power.
Thanks for the reply, however, it does't solve my problem, the backlight is completely turned off, theres no backlight at all, which mean you can see nothing even under completely dark condition.
Btw, this issue is gone while on charging(PC/AC).

So I am the only one so far has this issue？
After a clean boot(hard reset)it still happened, some times the backlight is even turned off when it's booting up, and I cannot active the backlight by tapping the screen.The only solution is press the power off button twice.
This is really weird...
Someone please help...
After the battery fully charged, the backlight won't turn off until the power drop to 50%, the only solutions I found is keeping the coreplayer running in the background, and the coreplayer will stop "something" to turn the damn backlight off.
I guess it's hopeless to find out what the problem is, as I have used WM phones for many years and first time has such weird problem.
OK,HD2, I am giving up you.

The only thing I can think of is an additional program that you may have installed... hmm but after a hard reset it should work.. well i could suggest that you flash the stock ROM over the current one... I mean not HR.. but flash the ROM in active sync mode connected to the PC. Could be that your shipped ROM has some errors.. which ROM are you on? Check the wiki to download the official ROM that match yours.. download and flash over the current one...
Try this:
HKCU -> ControlPanel -> BackLight -> BatteryTimeoutUnchecked
HKCU -> ControlPanel -> BackLight -> ACTimeoutUnchecked
or
HKCU -> ControlPanel -> BackLight -> BatteryTimeoutTemp
HKCU -> ControlPanel -> BackLight -> ACTimeoutTemp
Play around with these.
It's not always helpful but sometimes
My current rom is 1.48.832.0,which is a Asian WWE rom, I can only find the Asian 1.48.832.1 ROM, but it said this rom dosen't fit my phone when at 2% progress...
I am enough with it, this issue is only disappeared when battery is full, when battery drops to about 70%, it happens again.
So I can consider this is a hardware issue after charging on a AC power, and the led is flashing during chagring .

I am having a slightly different issue, but it is also related the backlight option. I have set up my phone so that the backlight should automatically turn off if not used for 1 minute (I have ticked this box in settings). Unfortunately, for some reason the box keeps getting automatically unticked, so the backlight remains on even if I am not using the device, unless I press the stand-by button. As you can imagine, this is really affecting the phone's battery life.
I don't have any major registry editor installed, except BSB tweaks (set on Low power mode) and have a stock ROM (WWE 1.66). Anyone have any ideas?

Hi
I seem to experience this problem on all HD2s. I activated the phonelock on HD2 and used a simple PIN for unlocking it. When I'm in the LockScreen, keying my PIN, the phone goes to suspend mode (or it seems like it, since the screen just blacks out and i need to press the power button again to see the lockscreen) after about 13 sec, everytime. This phenomenon happens only when phone is using battery power. It works fine when running on external power.
Is there a way disable this issue, or extend the time it blacks out. I'm using the default WM6.5 rom 1.66.707.1
Please help, Thank you.
same problem with me ! any solutions ???
settings menu all settings system power backlight
try increasing the timeout.
also settings menu all settings lock
see what options are in there. (mine won't start so i can't test it.)
I have tried all the settings i can find on the phone. I even tried changing Registry values that might be related to the timeouts. but still the same.
The screen will black out even while you are typing, so this rules out all the timers that will suspend the phone when idle for too long.
Please help, as this is a big issue for me.
Thanks.
Hi guys!
I noticed over quite a time, that while I leave my phone charging over the night, any random notofication will cause the screen to stay on until I wake up and manually turn it off.
On my galaxy s2 I have VillainRom 2.1.0 (Android 2.3.4) with ninpho's 2.0.4 kernel.
However I did notice the problem before with VR 1.4 and CF-Root kernel (didn't use anything else yet), so I figure it might not be related to this.
This is rather annoying, as I don't want any burn in effects on my screen, but there's a much worse part about it:
It's noch 100% limited to the time of being charged. If I remove the charger at 100%, play around a little with the phone and then go to sleep, some random notification (whatsapp/sms etc.) will still cause the phone to wake up and not go back to sleep mode.
What happens is, I wake up with a phone at 50% battery (at it's best!), or I don't even wake up because my phone is dead and therefore my alarm clock stays quiet..
I read about some people having this problem with their SGS1 and it might help to go to Settings -> Applications -> Development -> uncheck Stay awake.
SGS2 does not have this "stay awake" option (or I'm seriously stupid)..
Anyone an idea what I might want to try?
Best greetings, Alex
At that screen I have "Standby" and you need to have it unchecked. Also, what's your screen-off delay? You don't have any apps like screebl keeping you screen on, I assume?

mine just started doing it. i have been running custom rom for awhile now.
apps recently installed:
words free
launcher pro 806
extended controls
impossible level game
I have uninstalled:
words free
impossible level game
my issue is still happening.
when unplugged screen turns off.
I can get a text, it will light up then turn back off.
when plugged in (charging)
display will not turn off unless i press the lock button.
if i get a text the screen turns back on and stays on unless i press the lock button again.
I have recently re-flashed, complete wipe of phone and factory reset wipe.
I still have the screen on when charging and no option to disable.
I need an option to disable the "stay awake"
As my fault occurs with the phone completely reset on a stock rom it must be hardware so I am going to return it and see what happens from there.
I have flashed CM7 and there is an option to turn stay awake off.
This option is removed in DarkyRom.
Finally figured out how to turn it on or off!!!!
install the app extended controls and add stake awake as a toggle.
Turn it off!!!
then remove app
FINALLY!
Hello guys, I just noticed strange bug/behaviour. If my battery is around 10%, touch screen is not respondig as it should (also touch buttons). I have to tap like 10 times on some tile to open it and then tap another 10 times on back button or home button to jump of from app. As soon as I connected the charger, phone is behave normal, like new
Does somebody else notice the same behaviour or its just me?
P.S. Tried to reboot phone twice. Battery saver was off.

Can you check under settings -> applications -> Background tasks?
It more looks like plenty of apps are trying to sync up or use the resources. I might be wrong, but this did happen to me even at about 55% battery. But not as bad as 10 taps. I just felt the app launching was a lil slower than normal when I had ample background tasks.
Didn't know about "Background tasks", thanks
Currently I have only "HTC Hub" there. I will go and check this setting next time when I occur this problem.
But anyway, shouldn't reboot kill all background apps?

Reboot surely will kill all background apps. But these background apps are different to other OS. They are those that will 'start on boot'. So after reboot just in few seconds, they will get to their business as usual.
I love this 'background' task feature! No other OS does it so efficiently as Windows.
The good thing is if you check that place often, you will know what apps are 'going to run'. It doesn't mean they are running all the time. It tends to indicate the capability of them to run.
So as you said you just have HTC Hub, which is same on mine. However, when you to go 'advanced' option on that same page, you will see a list of greyed out apps that are going to run in background and you can't kill them. Reason being these apps need to be told about not running in background by entering them individually.
See if that greyed out list has some huge apps. I downloaded this gMaps thing from market and although I just looked for maps once (a day ago) since then, it's been running. It's because it kept on looking for my GPS co-ordinates. Now that dint freeze my phone (1.5 Ghz, I know!) but it drained battery quicker. Changing attributes within the app, removed it from greyed list and happy days!
In a nutshell, very intelligent task management. You can choose what can run and can't run while your screen is off! + you get benefit of battery saver option if you use that so you can choose who can connect to 3g network and who can't while you are not looking at your screen!
PS: whole point of that long post was : Most likely it's not a background task that's hogging your processor, but it's worth looking under advanced and you might know what app was it.
Hey, that was a long post Thanks for clarifying. I just checked Advanced tab and there are only HTC hub and some Media something (I have it in Czech so don't know the exact name in english)
Anyway I will keep my eye on that menu and in case of any issue I will check it and we will see
OK guys, here is the update. It's still happening :/ Everytime battery drops under 10% phone cannot be almost used. I have to tap everything 10 times to get it done. Checking background task was not helpfull, only HTC Hub is running (even if I kill it its the same).
So...I don't know...maybe its a bug (some power-saving feature thats is not configured properly?). I was used to behaviour when my mobile works even with no battery left like fully charged. No change in behaviour...

As a last resort - try a hard reset. I've got many issues fixed that way.
However, can I ask how closer to the release did you get this phone? Here in the UK there seems to be two separate batches dispatched. One which was at the release - which is buggy batch. I got my new phone sorted from someone I knew at the store and so far not a single problem from the earlier handset is seen. Battery is drastically better too (it was better on earlier one already, but this is very pleasing!)
Try hard reset, if that doesn't solve it, I would recommend to swap it if you can.
Hello everyone,
I am facing the exact same issue on my HTC Titan - when battery is low (battery saver turns on), touchscreen becomes unresponsive. This is very annoying since it usually happens when i get an incoming call and i cannot answer it.
Did anybody try hard-resetting the phone in order to solve this issue?
Thanks for the answers!
Regards
Hello there... I have the same problems too. I don't try to do hard rest for my titan. It is very annoying for me. Also some time my touchscreen becomes unresponsive even the battery charging is more than 50%...
Yeah, I get this issue too, it makes the phone unusable until you get to a charger. I find that it comes in stages, it sometimes is really bad then works for a few seconds, then stops again.
I have checked all my background tasks and nothing is really running.
I have this issue too. I got this phone only yesterday, and when my battery reached 10%, touchscreen became unresponsible.
Guys I think I've mentioned this in the FAQs thread, but ..
Everyone with this issue - please tick the box under battery saver, where it says 'automatically start.... '
If you phone goes below 25% without battery saver ON, it will lag/freeze - the screen response.
However with battery saver on, you will be able to use it till you go below 5% or even 3% when it gives you the 'critical battery' warning.
This is HTC screwing with us!
mine has the completely opposite problem!! when the phone is charging, the screen becomes very unusable, in ex. i press the phone tile, the screen registers my tap, but it understands that i pressed the tile below or next to the one i really pressed. or i happen to scroll down or up, the phone hesitates for a second and then scrolls but it is very jumpy and jittery, unlike normal use. some times it doesn't even register my taps 2 or maybe 3 times in a row!!
the only workaround i've found is not to use the phone when charging
is this happening because of a faulty charger, maybe the phone is experiencing a short circuiting situation??
(i forgot to mention that i have the phone only for a week!!)
thanks

I have battery saver enabled and even with the heart icon in the info bar at the top, the screen is still unresponsive.
Same here! i thought it was just my device that was dead or something, even since it's only 2 months old!
I did a hard reset and it solved the problem, it must have been something messing it up.
Nope...I have tried Hard Rests...ROM Changes etc...but its still the same problem..
Does anyone here think its a hardware problem ? or something else?
Any geek suggestion would be helpful

That happened to me today. Then I did a hard reset and now my phone won't go past the carrier logo (the one after the HTC logo, and before the windows Phone logo)
I just did a full factory reset of my stock rom and finished restoring my apps but for some reason the screen won't turn off when I leave the device alone.
Screen timeout is set to 30 seconds but no matter what I set it to, the device never ever sleeps. Also if I press the lock button sometimes the device will wake itself and and the screen will come back on permanently... I've looked in the process manager and nothing is running in the foreground.
Here is a logcat. Can anyone make sense of it?
I have no idea why this is happening after a fresh wipe on a stock rom.
Just try this.
Go to settting --> Display --> Touch key light duration --> Change "Always on" to either 1.5 seconds or 6 seconds (as per your choice)
If it works just HIT thanks button.
The touch key light duration has nothing to do with why my screen won't turn off...
Thanks anyway..
Do you have any alarms set?
EDIT: in developer options do you have stay awake set on? Also if your not plugged into USB maybe you should try and clean the USB port.

Hey thanks for the reply. No I have no alarms on, the USB port is very clean and I don't have that option in my 'Developer Options'. :/ I really would like to know what is going on...

Hi leijonasisu,
My samsung has just developed the same problem whereby the screen won't turn off ever. It happened since the battery went completely flat two days ago. I'd love to know whether you found a solution to the problem, because it is draining the battery at an insane rate!

Hello everyone, im new to this place but as far as I could read my cellphone having the exact same symptoms as the threadstarted stated.
I do have the "Developer options" tab and also I would like to add another symptom.. After the phone is fully charged, the green icon at the top-left corner of the screen wont dissapear after I disconnect the usb cable.
- I do not have the "stay awake" settled on.
- I do have multiple alarms but just at some exact point each morning.
- The only way I can shut the screen down is by pressing the lock button.
- I'm running 4.1.2 as the android version.
- My model is the GT-I9100
Is there any other thing you guys would need to know ? thanks in advance for the possible help provided.
Flash a stock firmware via odin.
Then all will back to default.the same look when you bought it.
Or flash a custom rom with device option in settings.you can controll the screen behavior there.

Root your phone and flash a custom roms.
You'll find one at the dev section.
Dont like the custom rom and stay on stock?
Do a factory reset.
Settings - Storage - Erase all data
This will erase your user data and downloaded apps.So do it at your own risk.
Goodluck

I just had the problem on my Mega, where the Power Button would bring up the Power Menu on a long tap, but would not turn the screen off when I just pressed it quick, like it used to. Nor would the screen shut off with the Screen Timeout set either.
When it started this problem, I also noticed that the solid white screen that would appear during part of the bootup no longer appeared.
This got me to thinking. I'm Rooted on the Factory v4.2.2 ROM, so I installed "XBlast" and went into it and checked the box for Disabling the Boot Animation (SU should prompt you).
Anyway, I rebooted and the problem was gone! I can turn the screen on and off with my Power Button again!
This all started with yesterday's Google+ update making my system go haywire! I had to restore from a previous NanDroid backup, but this one issue remained. The Bootup Animation must have got messed up somehow and affected it and disabling it stopped it from interfering or something.
This helped me and I can deal with having a way cool boot animation later if I want. But at least my phone's screen turns off now and maybe it'll help you too.
Solution!!!
This problem is usually caused by the usb charging port, which is why a factory reset doesn't fix it. It's a hardware problem not a software problem.
1.
First thing to try is cleaning the usb port with a small dental bursh (or whatever you can find) and some surgical spirit which you can find in a pharmacy,
Take the battery out and unplug the phone when you do this.
2.
If that doesn't work then you can try the method that worked for me. Full disclosure: I invented this through trial and error, I don't know why this works and I can't guarantee you won't damage the usb port. But if nothing else works, then I say go for it.
For this method leave the battery inside, have the phone on.
Okay, so the port is a hole with a prong in the middle, right. Get a sewing needle and insert it into the space between the prong and the hole, specifically the place where the prong is closest to the hole wall - all right? The prong should be much closer to one of the walls than the other walls, put it down there, it won't fit unless you force it a little bit.
Put it in as far as it will go, then leave it for a little while. Turn the screen on and wait, see if the screen turns off. For me it usually works after five minutes of having the needle inside. I HAVE NO IDEA WHY
Dear all!
I am really in despair
I notice a strange phenomenon on my Galaxy S 3 (German version).
Sometimes there occurrs a flickering of the screen. It is caused by thin greyish horizontal lines which jitter with high frequency at some parts of the screen. You should not imagine it as some blinking of the whole screen. It's only a partial jittering of thin greyish lines.
It does appear at random, I cannot force this effect to occurr. Most of the times it's subtle, but sometimes it is clearly visible.
I read in some other threads that people noticed flickering in dependence of the power saving options. This I observed as well. But I don't know why. Unfortunately, none of the other threads came to a conclusion. And the problem seems to affect only very few devices.
My S3 was sent into repair twice. Two times the touch screen was exchanged. Last time they also changed "some electrical and mechanical parts". However, the flickering still occurrs.
I now tested for a while and made the following observations:
- it's not related to 3g, wifi or mobile connections in general (occurred while switched off)
- it's not related to "automatic brightness control" (occurred with manually set brightness, 1/3)
- it's not due to the display (they changed it two times)
- it's not related to ambient light (happened both with artificial light and in darkness)
- it's not related to the setting "adjust display color"
- neon light helps to trigger it, as well as switching the screen on or manually changing the brightness
- it's not related to any one of the single settings in "energy saving mode"
- flickering "survives" switching the screen off for a short time
- switching "energy saving" off always finishes the flickering
Can anyone shed light on the reasons for this?
Try unticking the second option in Power Saving mode, which is supposed to lower the FPS in order to preserve power. You can still user PS mode but the flickering should be gone.

i already unticked all single options there. didn't change it. the only solution is to switch the whole "enrgy saving mode" off as it seems.

I am using PS mode with all the options checked all the time, I don't think I have ever disabled it, and I haven't noticed the issue you mention. Can you tell us more about root status/ROM/kernel on your device etc? Also, have you tried disabling PS mode and observing the phone for 24 hours or so, to see if it still does the flickering at some point?
I'm having same issue. As for the conditions my result is that it would only appear after wake up when power saving is on with lowest brightness. Also it's not noticeable on dark wallpapers. Any ideas other than "turn off" power saving mode?
Just to add, I'm running stock 4.1.2 version which didn't fix this problem and I was observing phone without PS for a few days without any flicker of this kind.
