im just wondering after a while of not using my phone the backlight gets reverted all the way dim so i cant see anything on my phone. Luckily i have it on my today screen and i can see just enough to fix it. is there any way to fix that perm so it doesnt do that.
maybe see this thread - doesn't contain a solution, though:
http://forum.xda-developers.com/viewtopic.php?t=51415
I had a similar problem struggling with PocketZenPone and found following issue: There is a checkbox in the energy settings: switch on backlight by tapping on screen (i dont know the exact phrase because i have got a german ROM). Double check if it is checked. If not check it and your problems are gone. Post the result here please for the other guys.
Thanx.
well the thing is ive done that before and well it still reverts back to that setting after a while

Do you mean you have double checked that issue and recognized that the option is not checked although you have checked it.
Do you mean it is unchecked automatically? If so this is a crucial information for all.
I had the same problems some days ago,
Didnt work to check/uncheck softreset.
I went to registry and did it there, and now it works.
johnny which key did you go to
I´m so sorry, i dont remember.
But it was in hkcu\controlpanel\backlight
Try change backlightontap and batterytimeoutunchecked.
That sounds good.
I would revert them and softreset then change them the regular way again (if its not ok.)
So probably i did it at that time.
ok this is getting real annoying this didnt start happening til i upgraded to 2.21. Now everytime i go into standby it turns my back light to very dim and i gotta go and reput it back to bright is there a program that might be doing it.
i have wisbar, resco explorer, resco pocket radio, pocketbreeze, phm reg editor. installed any one else have any problems with those messing with the backlight
i also have memaid, pocketzenphone 6
nm i figured it out thank you all for yourhelp

any chance you can tell me how you did it cos mine keeps doing it
I already posted in the sticky but didn't get any answer.
My problem is one that occurs quite often how I see but still I don't find any solution.
The problem is that the screen of my HD doesn't show up anymore when it was in standby and I left it for some minutes. It's on because I can still change the loudness and I can feel the buzz of the buttons when touching one. It takes me some luck and time to bring it completly to life again by pressing over and over the ON/OFF button. When I bought it the problem occured very rare but now it's happening all the time when it is in standby.
I never did install any roms (because until now I have no idea what it is about ), the only things I have done so far:
Installed TomTom 7.450.9028 and these two registry edits:
under HKLM\Software\Microsoft\Inbox\Svc\POP3 i renamed the mailtrns.dll to mailtrns2.dll (it's a fix for the email because my GMX account didn't work with POP3 on my phone) and the other was setting the value HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/GPSIntermediateDriver/Drivers/GPSOneDevice/PollIntervall, to get better GPS-Signal
Everything else is just original, like it was when I bought it some days ago.
Is there anything I can do? Or do I have to send it in?
I really like the phone and it's working perfect except to this point so I'd like to stick to it. Hope you have some advice,
THX in advance,

Have you tried going to Start > Settings > All Settings > System > Power > Advanced and making sure device isn't set to turn off after a period of time?
Thx for reply but doesn't that mean my phone will be always on? Or can I set it then manually (by pressing ON/OFF) in standby and turn on again without problems?

Yes to both, it will remain on unless you manually put it into standby by pressing on/off
Ok, I try it out now. Hope it works that it comes on out of standby without problems.
Wow until now for exactly 1 hour and 33 minutes no problems. Seems to work, hope it will continue like this, if so I could kiss you

Could be difficult (grin).
well, i was following a thread about it, but i guess it was deleted cause it was in wrong area...
if a fix was found please tell me! =oP
it seems to be a commom issue: when i try to turn off the phone, it just turn on again...
what i've done until now: i was running cm7 and i believed it was a rom related issue, but i'm back to uk stock (1.32.405.6) and keep it with no root (just ship s-off that remains after flash ruu), and the problem remains, just take a little longer to turn on again... BUT, when i plug it into pc by usb cable it stays off, when i unplug it turns on again...
i'm tending to believe that's a hardware issue, maybe a short in phone plug, but in this case, it is the most commom issue that i've saw...
any idea is welcome
thanks...
Edit:
Okay Folks, looks like the "fix" was found. I made a little summary for the next generation! =oP
this weird issue happened due summer time changes (don't ask why), but after March 27 the phone simply didn't stay off, if you tried, it just turned on again.
The "fix" is:
- disable automatic hour update (just in case)
- remove battery and let it out for around 10 hours, then put it back and turn on!
- Hour and date may reset (or not)
- now you can reactivate automatic hour update if you want.
- the device just stays off properly again

XL3N7 that found the problem,
Rodomar705 that found how to fix in this thread: http://forum.xda-developers.com/showthread.php?t=1014520
And everyone else that probally lost every data (like me) so many times trying find out how to solve it. =oP
I really dont understand why the admins deleted and not removed the thread from the development section.
What really happens: I have my dhd with cm7 around two months now and i always flashed the nightlies.I know the issue, when the phone is powered off and plug a charger reboots in cwm recovery. I never had problem just to "power off" my phone and actually did that every night before going to bed (so i know that the "power off" used to work ok) .Two days ago i flashed RC3 , power off worked ok, then nightly 32 and next morning i had the issue.When i select to "power off", without any charger or usb connected , phone just reboots.Just to remind you that if the phone is powered off and you connect it to charger then the phone goes to cwm recovery!So i tried various combinations :
1. Back to stock 1.32 (both with img file and exe file). After that flashed 3.0.0.5 and the newer version of cwm
Phone powered off correcty and the vol down+power goes to hboot.After flashing cm7 problem appears again.
2. Also had a backup and load it (nightly from 16/02/11) but still the same problem.
Please devs tell me what kind of files you need in order to help me solving the issue.
Also i see posts from guys using other custom roms and having the same problem, so i dont really understand why the admins deleted last night the thread started in development section.
You guys using customs rom just check if your power off works and if you have problem write it here and hope not to be deleted.
@thiagodark I think you have to change a little bit thread's title
same problem!!....i think is a bug of CWM...or there is a conflict between recovery and "idontknow"!!....
this situation is funny ... we are afraid to brick and our DHD doesn't want to turn off...
well, i think my problem is a little different, cause i get this problem even after flash official ruu, i'm all stock right now and the phone keeps reboot when i try to power off. when i select "power off" with micro usb cable connected, it works okay, but when i disconnect, it power on again.
Also, sometimes when i try to power off with or without the micro usb connected, it just dies and the only way i can power on it again is by removing the battery.
suggest me a tittle and i change, as you can see, my engrish is not something i can proud myself! =oP

Ok, I think I have found the problem.
Go to settings --> Date & Time, untick the option to use network values and set the date somewhere before the 27th of March when the daylight changes took place. Reboot and power off. The phone should stay off (at least it did for me). Now power on, go to date & time settings and tick the option to use network times. Power off and it will probably come back on.

No its not a bug of 3.0.2.4 r1(i had 3.0.0.5 when problem appears). As i wrote everything worked perfect (cm7+cwm 3.0.0.5) till one morning (was on cm7 nightly 32+cwm 3.0.05) want to boot in bootloader, so i select to power off.After that never powered off.What makes me nervous is that i didnt install any appl or changed the cwm recovery version.Nothing like that.I always powered off my phone so i know that there is not cm7 nightly related.
So the big question is what changed in a few minutes?

I have no idea m8. I've just put 2 & 2 together. The issue first appeared shortly after the time change. Maybe a bug in htc's code? Surely not a cm thing. I have tried fastboot erase system -w and the problem was still there. I have also tried different radios, cwm versions and the issue is still there. Probably HTC. Hopefully one of the greater minds of this forum can pin point the issue.
Perfectly good work around
Hi, If you want to, you can untick the setting in Date & Time and install Clocksync from the Market. Using this app you can sync your phone's time at whatever schedule you like to the atomic clock (it is much more accurate than HTC's provider).
This will enable you to shut down correctly and have accurate time displayed on your device.
You need root though.

Hello
I have my G2 for 3 days now, and I keep having the same weird problem every morning when I turn it on: the clock "looses" one day, and either advances or loses a few minutes.
Yesterday I checked as the hour went past 00h and the date changed to day 19, thursday ('I'm on GMT 00). The phone and computer had the same time.
I left my phone off during the night, and today when I turned it on I found it at 10.00 o'clock (8 minutes in advance of my computer). It also switched back to the 18th, wednesday. The weather/time app still detects it was last updated on the 19th.
I have automatic date-time-timezone switched off. If I turn it on, it will sync with the Internet and correct the hour, but that does not fix the problem.
Any ideas on what's happening? Any suggestions?
I'm on Android 4.2.2
Kernel 3.4.0
Software D80210b-EUR-XX
Yesterday (after midnight) I switched the phone off for more than 10 minutes, switched back on: all ok
Restarted the phone: was ok - up till 3 am the date/time was correct.
Turn it off, woke up this morning, turned it on: 5 minutes delayed, date went back to the 19th.
It seems what is happening is not really a lost of time. Today as I turned the phone on, it was showing 10:24, 20th (yesterday). This was over half an hour ahead of correct time. This happened after I had the phone off for 3 hours, so it's not a delay that increases as proportional to the time the phone is off. It must have something to do with some date/time on the settings, that override actual date/time.
I think this is like a "return to last settings", in this case, I believe this was the date/time set when I turned the phone on yesterday morning.
I already went by all apps I think could be related, but I can find no relevant option to prevent this.
That is indeed strange, maybe someone else around here can help you with that.
I don't think many people turn their phones off during the night.
Hi i think this is the same for all g2, my phone does the same thing once you turn it off the device is literally off. I am sure if you check the battery time it will show only from the time you rebooted it and not from last full charge. At the beginning i reported this issue but didn't get any reply but with further investigation i reached to the conclusion it wasn't an issue with device.
Any way regarding date time issue, you can simply make sure its automatically synchronized with network that way no matter whether its on or off it will be correct.
Sent from my LG-D802 using xda app-developers app
its probably cmos battery if phone has one, try warrantee
Thank you for your input
I've done a few more tests. I've flashed a different firmware, but it still does the same. This originally came with 10B-SEA, and I flashed it to 10B-EUR (UK open). Now it's back to SEA.
I've contacted LG about this, and they told me it's under analysis.
The phone will not loose date and time if it's powered off for one hour. After two hours it will happen and it will go back to the last time the phone was powered on and the clock was set.
I've been keeping it synced with the network time, and that way it works fine, but that's not a permanent fix. Yesterday I unchecked the automatic time, left it powered off for two hours, and it went back to monday.
I've read this post http://forum.xda-developers.com/showthread.php?t=2580974, and it seems to be related.
Same problem with date and time
I do have the same problem. My phone model is D802 (international variant). But as far as I remember, this issue did not start from the day one. I purchased the phone some 2 months back. It was fine on the JB. It remained fine even after the KitKat update. But one day, my phone did show some weird problems. Serious lag coupled with overheating and battery drain. I did a factory reset because the phone was hardly usable at that point. After the reset, lag + overheat and battery issue was gone, but I remember that after that incident, it started this weird date/time sync issue. There is something which I wish to highlight by the attached screenshot. There is always a broken curve of battery usage whenever the date/time reverts which happens whenever you keep the phone switched off for a few hours. I am not a technical person, but this might be related to the battery.
Anyone have any luck with this? The main problem that this is causing is that when emails, texts, messages come in whilst the clock is incorrect (before it updates), these items get put out of sync with when they did actually arrive.
I contacted LG and they said...
If you have both options ticked, I would advise you to try and perform a hard factory reset. Before doing the reset, please ensure that you back up all of your files as all data will be lost during the reset. The details of the reset are as follows:
Turn the phone off
Press and hold the power key and the volume down key together
Release the power key only when the LG logo appears and immediately press and hold it again
Release both keys when the hard factory screen shows up
Select yes (use the power key to select yes)
Select yes again
This will then take you through the set up of the phone, and the issue should be resolved. I hope this helps you.
I haven't yet tried this, as from what I've read elsewhere, this wont fix it, plus it is a bit of a hassle to copy everything off and then reset, then et everything back on the way it was and all apps, etc.
Hi,
I've the same problem.
Can you tell me if Hard factory reset or LG support had resolved this issue?
I'm currently using ClockSync app that sync time every 3h and at boot.
The clock seems not to be very accurate : 1.139s of local offset in 2h...
I've tested the Clock_offset_fix. I'll update this post when I'll be sure that this solution is ok for me or not...

This is not an issue per say. It's just that the device is built this way..... So as far as I know there is no fix to this. Except you can have accurate date and time if you have a sim card in the device and auto date&tme option is ticked in settings. You see the device doesn't have a pc like cmos rom to store basic info like date and time. So when u turn off the device that info isn't maintained and becomes corrupted after some time but it is corrected when synchronized with the cell network provider at boot.

Same problem for me, date and time are wrong for some seconds after boot.
Than it switch correctly to the current date and time.
Make sure you have setting > date and time > automatic sync for all options...
On my phone it start wrong than it correct itself if internet is enabled.
The problem ia when mobile data is OFF. :'(

when turning my wifi off it seems it goes into some weird loop of turning on and off constantly by itself, it doesn't seem to be trying to connect just flipping the wifi switch on and off none stop.
noticed it because i had a huge battery daring overnight and while trying to fix it i saw the switch going off and on all the time.
when turning it back on it seems to connect normally .
did a network setting rest but it did nothing ...
I'm guessing a factory rest will fix the problem but I'm hoping to avoid such a overkill solution :crying:
does anyone else had this problem and can help me fix it?
thanx!

original samsung rom.
just happened (i have the device for a a while everything was fine) its the android system that drains the battery in the battery status.
when i leave the wifi on it stops and works fine ...
Have you turned off ''Keep Wifi During Sleep''? I know this can drain battery.
It's not so easy to troubleshoot on an orginal none rooted phone.
You can try clearing dalvik and cache.
Turn it off and then on holding power and vol down button, then clear cach/dalvik and restart.
Try uninstall update beaming service for samsung then restart
If still persistent try uninstall update microsoft onedrive and skype then restart, just in case
I found it after factory reset (forgot internal data backup :crying and update all apps, this problem occuring after the last 3 updates (beaming, onedrive, & skype) which more suspect beaming service update make that problem
Your not alone
You're not the only one who suffer from this exact problem, on Friday or Saturday the same problem started occurring with my phone too, WiFi turns on and off in a loop and huge battery drain!
I saw an increase of 6% of battery drain per hour, so I ended up on 9% total drain every hour. :crying:
I have original Samsung Rom and phone worked prefect until now, no settings or apps installed before this happened either.
What rom version are you guys on?
I'm having the same issue. However, I'm on PhoenixX Rom. Major battery killer and has only just started happening within the past few days.
Since my phone has been unplugged, 3 hours ago, looking at BetterBatteryStats, It is showing com.google.android.gms as having quite a LOT of wakeups. 40 per hour (everything else is about 2). Don't know if this is normal as I don't remember it before the Wifi issue.
Looking into what the wake ups are caused from, Location and heartbeat were the major culprits. So i have turned of WIFI scanning when not on and also the body sensors for Google Play. We shall see.

its not a fix at all . it dosnt scan for wifi , just turning it on and off non stop.
like pressing the light switch agin and agin
I had this after installing "GoodLock" software from Samsung! Uninstalled and everything is ok
same here, just noticed I wasnt on Wifi and the switch is just flicking on and off by itself. Standard S7 with all the updates installed
Been struggling with the same for some days (4 - 5) I haven't been able to get exactly whats triggering this. I'm on stock rom with root. I've reinstalled firmware clean again and re downloaded my apps but it is still happening randomly. Some times after a few attempts to switch wifi on (even when it is toggling by itself) it manages to keep on. Sometimes restarting makes it work again. One thing I'm almost certain its that this usually happens after I turn wifi OFF and then try to turn it back on.
It's been crazy and the phone starts to overheat after a while off this on-off loop.
Any ideas?
its very wierd it started to all of us in the past few days-weeks . seems like samsung has a bug they need to hurry up and fix.
AT&T just pushed out the October Security update for the S7 family, I'm guessing something that came along with it is creating the problem.
mine did a software update last week and I've been away in airplane mode so it could have started then. I've just disabled scanning and that seems to have got round the issue and I'm now connected to WifI
I'm not sure whether it is a Samsung Issue or a Third party one... It is true that something recently affected all of us, but as far as I know, it could be a third party app that wasn't well developed for our phone.
I've noticed the same problem on my phone and it's also only started up in the last few days. On stock Sammy rom, unrooted. Will be monitoring this thread to see if the experts here can narrow down the culprit.
I had the same issue and I was able to stop the toggle by turning off the wifi scanning in Location - Improve Accuracy - WiFi scanning. It's a fix for now. I think it may be an app that may have been updates that is persistently looking for location updates.
