I have had this tablet for about three years now I guess, and over the past few months, it has developed an odd problem. When first turned on, the brightness is at a normal level. Once you stop using it and the screen goes into a sleep mode, the brightness will be about 50% dimmer when it wakes. The brightness setting does not change, just the brightness itself. A restart fixes it until it sleeps again. I am rooted on 5.02. I tried a LG brightness patch that supposedly fixes an issue with this tablet caused by overheating, and that did not work. The problem could not possibly be being caused by overheating since it happens even after it is turned off for a while. I could try a hard reset of the tablet, but I am afraid it would break root on the tablet. I had a hard time rooting it and would prefer to find another solution! Thanks in advance to anybody that can help!
Sorry, no idea that doesn't begin with flashing the 22B TOT and/or the 11A KDZ to start fresh.
Hope you find your solution.

If I have the hardware keyboard out and the phone goes into sleep mode and I close the phone, when I hit the power button, I get the issues shown in the attached images. It won't respond to anything unless I open out the keyboard and close it again or, tap on the notification area and close the notification screen. No issues if the phone is not allowed to sleep.
Don't want to hard reset if I can avoid it, anyone else had this issue?
I have never seen my device do this, but I don't think I have ever let my device go to sleep while in landscape.
To avoid this, why don't you just change your backlight settings? While on battery power, set the backlight to turn off if idle for 5 minutes or something. This way you'll never have it fall asleep on you. Unless of course you read extremely slow and a page takes 5 minutes.
Was thinking about increasing the backlight settings for a bit longer. I had that situation by chance last night and tried various things, uninstalling software, bluetooth head set, changed radio, hard reset and even task29 and a new flash, still same issue.
Just starting to get fed up with these little annoyances, would be nice if it just worked, lol.
Wow that's rather odd that you did a hard reset and still had the issue. That would suggest that it is most definitely device specific. Maybe you can call your carrier, and if it's your lucky day they can replace your phone. ??
Why no try Energe ROM, It has no such problem.
Yesterday i flashed lates CM10.1.2 Stable. After that somehow display didn't work properly. Waking up the phone from standby took about 5 seconds.
I was little bit afraid to brick my phone so i flashed Stock Firmware EU-Open with KDZ.
Now i have really bad Display Problems.
Starting the phone works nice, Display works nice, UNTILL !!! the phone going to standby.
Waking up from standby works but Display is completly Black. The three soft buttons have light but very very dim.
Like i said Display is completely Black and it's working but you need some brigt flashlight to see something.
Adjusting the Brightness with slider doesnt work.
If i restart the phone the Display is bright again but Brightness slider doesn't change anything in brightness.
I think this could be some Android system software failure. Because the Display works just nice if i restart the phone, it's not hardware failure.
Now is there any other flashing method to completely flash the Original ROM like it came from factory.

I just recently got a T217S from Sprint, had it about 2 weeks, running all stock, 4.42 Android. Ran fine the first week, then I noticed that the screen would start to flicker. Doesn't change colors, just flickers. Playing with the brightness can sometimes cause it to stop temporarily, but it starts again almost immediately. The level of brightness doesn't make a difference, neither does any applications I'm running. I've rebooted it into safe mode and without even touching it, it started flickering less than 30 seconds after booting. I've google the heck out of this and it doesn't seem to be a hardware issue, but an Android problem. I would like to avoid a factor reset if I can, especially until I get solid proof that it would FIX the problem. So far, no one can even tell me WHY it's doing it.
HELP???
Hello,
I use the last fullmics rom and i used it for atleast 8 months, but since yesterday my phone became crazy, if the screen goes off i need to put out my battery and put it on again! my screen brightness is always at 100% and i can't adjust it,
It's a known bug or it is a phone problem?
Try safe mode. See if its a rogue app
Hello All,
I know there have been a lot of touchscreen issues with the G4 in 2015 but is it still happening for some users? The touch screen issue i have been having is very intermittent and only occurs when you wake the devices up. So when you wake the device no touch input is detected. I can tap any where and it will not register any touches. I will then put the device back to sleep and wake it up again, then it'll work normally.
Not sure if this is normal but is anyone else having this issue? Should i be concerned or RMA the device or is this more of a software bug?
I can use all the diagnostics test tools and it'll pass since the issues is not lagging or missed touches.
Thanks all!
Try to reflash the firmware via lgup or lg flashtool
I have this problem too but it seems more random than just when the screen wakes up and has occurred while I've been in the middle of doing something on my phone. It's simple to solve by turning the screen off and back on again but it's very annoying when it happens.
Yeah, that sounds really annoying....Wonder if it's a bug. Going to try a reflash and retry. Hopefully it'll solve it.
