[Seemingly Solved]New to LG G3 D851, Annoying brightness problem!!

I just got a G3 and every time I reboot, the brightness resets itself to 100%!!
Auto brightness is off.
Is this a known issue? Is there a fix? The phone is rooted with twrp recovery.
Please and thank you!
Seemingly solved edit: So I pop in the sim card after getting everything set and rooted and all that jazz...Why would a sim card not being inserted prohibit the brightness settings from sticking? I couldn't tell you. First for me.

What if you set the brightness as Auto ?

Even if the auto brightness is on, the brightness always defaults to 100% after a reboot. If the auto brightness is on when I reboot the phone, the auto brightness is off and at 100% when the phone comes back on.

Edit: Ok, not only does the brightness setting not stick, the screen timeout defaults to 2 minutes as well!!! Highly annoying, these two little bugs. HELP!!! :crying: :crying: :crying:
I usually use Nova Launcher, so I got around to installing that and it didn't make a difference. I've removed the slider from the notification tray, done a factory reset through twrp...nothing helped.
Really hope this isn't something I have do just "deal with". I'm about to get around to deleting all the nonsense LG and Google put onto the phone...hopefully it'll have some sort of positive impact.

Did the SIM card fix your timeout issue as well? My phone came with the sim card pre-installed but my screen timeout resets to 30 seconds after every reboot.

Can't stop phone from resetting Screen Timeout to 15 Sec

Posting this question in the general G4 forum as I got no response in the Verizon specific forum.
Can't stop phone from resetting Screen Timeout to 15 Sec. Seem to happen randomly (doesn't always do it on reboot, doesn't always do it on screen lock, doesn't seem to be a specific interval... but it does eventually reset to 15 seconds no matter what other interval I select). Any idea why and how to fix? this is driving me crazy.

Hey there.. I'm having the same annoying issue.. Mine resets to 30 secs.. I assume this is a Marshmallow or LG G4 problem.. cos my phone isn't rooted..

Save display settings not working

Hi,
I have a minor issue with my new LG G4. On the display settings we have 2 options:
- display timeout
- display brightness
For some reason the settings are not saved after I reboot my device. After each reboot my settings are back to default:
- default display timeout: 2 min
- default display brightness: 100%
The moment my phone has restarted and I log on, the settings are still ok. But after 10s, when the phone is up and running my screen goes to 100% brightness and my settings are gone.
If I choose 15min en auto mode, the settings are only working for the remaining session only.
Is this a known bug, or am I doing something wrong?
Android version 5.1
LG G4 (European version, Belgium)
Alle latest updates intalled
Standard apps, no additional apps installed yet

Anyone with the same problems here?

Hello ..... I'm on Android 6.. and I had issues with the screen timeout... I've enabled the Screen Timeout toggle on the status bar.. The options are 30 secs, 5 mins and 30 mins.. It seems to work on 5 minutes but I didn't wait that long to try it.. LOL.. As long as it's more than 30 secs.. I'm happy!
As for the auto brightness.. you can try the toggle but I didn't have any issues with that.. :fingers-crossed::good:
EDIT : The system went back to 30 secs after rebooting..... FCUK SAKES !!!! ....
oh well.. there are much more bigger issues in the world.. i'll just bite the bullet until there's a fix for this..

Hey there. I've got a slightly different issue. Every time I set my brightness to 0% auto, the phone randomly changes it back to 45% non auto. This annoyes me as it's blinding in the dark and also not very battery saving. .__. Does anyone has a solution for that? It seems not to be caused by overheating, though.
I've got the European Model H815 with official Lollipop installed.

I posted the same topic on another forum.
1 user had the same problem. No workaround but he installed Lux Lite to manage his display settings.
I'll try it out later.

Screen not turning on

Hello, my Xperia Z5 Premium(E6853) has had some issues with it's screen recently. It started as a flickering of the brightness. I flashed a few different FTF files(The Austrian T-Mobile one and the generic Italian one) but the problem still persisted. The flickering was making the device near unusable out of annoyance. So I stopped using it and switched back to my Xperia z3 dual until I could find time to try and fix it. However now the display refuses to turn on at all. I reflashed the FTF file making sure to wipe everything but the screen still refused to turn on. What are my options in regards to fixing this situation.
I would prefer not to ship it all the way back to China if at all possible. I checked with Sony care CA and USA. Both are unable to help.

Hello, how did your screen flicker? Mine ( E6853) changes brightness weirdly when it is close to screen timeout locking, it's like normal brightness then high and then normal again. I am scarred it might end up like yours a possible fix might be disabling auto brightness, I will try it on mine and let you know.
About your os flash, try reflashing the original files if you saved then and also make sure you are not using the dual sim ftf on your single Sim.

I atempted to flash my original files, it did not help. The flickering was a 2-4 hz flicker, like a florescent bulb that is about to die. My Z5 also did the brightness changing thing that you described, however my D6503 and D6633 also do the same thing so I would not worry about that too much.

I turned off auto brightness and the problem disappeared. Try charging the phone for 30min then open the sim flap and you can see in the left a small white button press it for 2 minute and the phone should vibrate ignore the vibrations and keep the button pressed, after this try to power it on, this might help. You can also try the repair my phone in the software update tab on pc companion.

PC companion "repair my phone" does not work with modified software. I also tried holding the hard reset button down for 2 min, no change occurred. I contacted sony mobile UK and they said they would repair it out of warranty. At this time this is what I will probably do.

Samsung Glaxy A50 Black screen after Time out issue!

I am facing this issue with my Samsung A50, when I lock or when the timeout occurs the phone doesn't unlock or touch, face unlock or anything doesn't work or appear on the screen as it becomes pitch black with everything working in backgound.
One thing to note I can hear notification sound and call ringtone after it goes black.
Things I tried:
Changing all settings with my Display like Brightness, Always-On display, Screen Timeout (Max timeout is 10 min in this phone), Battery mode (tried each of them).
Putting face Unlock so it can unlock the phone when it's blacked out.
Changing all different types of locks.
Changing the launcher.
Even factory reset+wipe the cache memory didn't work.
It's not in warranty.
I have to restart it every time to make the reappear the screen again.

Is it rooted ?
