Hello.
Suddenly my phone decided to stop activating the screen after I press the power button to wake it up, but the soft keys light up and screen is working even though I am unable of seeing anything.
Also the brightness function not working as well.
Any idea how to fix it or should I send it back to LG?
PS. My phone is not rooted and running factory 4.1.2

I bought it 12 days ago but I was wondering if it has to do with some settings to avoid the fuzz...

explain !
working screen but you cant see anything
brightness function not working on a dead / black screen?
No.
Let's take things from the start. Assuming that the phone is off when I open it the screen is fully functional. As soon as it goes into standby mode or by pressing the power button or after 30 sec or 1 min according to users settings the screen won't start again when you press the power button to wake it up.
As for the brightness setting is not working at all either I choose automatic mode or manually. I can only access the settings when I power on the phone when it is off.
I hope now it is crystal clear.
Try reformatting with new kdz

should have waited or my reply... we are not in same timezone. anyway its seems bsod a simple wipe or even kdz flash would confirm any hardware issue.
Thanks for the reply I will let you know as soon as I take it back....
Was the issue resolved?

I got the same as OP problem on my stock E971.
Hi there,
I bought a new LG G4 and after 2 days it started to work funny. In other words if I wanted to press power button when screen was off it didn't give me any response, but after I took out the battery and put it back the screen goes on and same if I do plug the charger the screen goes on.
- I tried to run phone in safe mode and it works without any issues.
- I done factory reset.
I have marshmallow android version. and also I have tampered screen protector (but remember it works without any problem in safe mode and even though my screen protector was since the first day of the phone I bought)
p.s. just an update just realized it does the same in safe mode...
any help appreciated.
Regards
just a thought,if you press the back button and the screen doesn't turn on,it might be because the sensor is covered(near the front speaker).
I have brand new G4 also. S/N 602. And it does the same thing, it has trouble waking up for some reason every few times. Double tap or power button can't wake it up, only thing that can wake him is double press power button to start camera. Same thing is on Stock and on Cyanogenmod.

Okay, I took off the screen protector and it works fine now.
could be that a protector problem ?
You most probably have a protector that is covering the proximity sensor. That's why the phone did not wake up.

Hello all,
I am using the original 5.1 ROM.
Now, I can turn on/off the screen by pressing the Power button, but that's it. The screen does not respond anymore to my touch . Then the screen is off automatically after timeout.
Could you give me some hints to fix?
Thanks

in my opinion, the touch screen is broken. try flashing different kernel, and see if u have the same probs.
Hard reset possibility...before concluding it's a touchscreen problem.
My phone is stuck at homescreen (pattern lock) and it only responds to the double tap knock screen on. I tried to draw pattern, tap on emergency call, camera on lock screen and nothing gets registered on touch, except for knock screen on taps when screen gets timeout. The double tap is recognized easily anywhere on the screen. I pulled out battery several times and restarted but same issue. I have also refreshed my stock firmware via LGUP Tool but didn't help.
Basically, my touch is only responding to the knock on tap. Nothing else. I turned camera on via volume down button but touch doesn't work there too. What could be the issue? If the double tap is being registered anywhere on the screen easily why is not registering my touch after screen on!?. Please help!

Since no ones answering.
Not a solution or fix.
But have u dropped it. Or anything like that. Had screen replaced.
Seen it happen on the note 5s. Sometimes the flex cable for the lcd can become partially dislodged. Enough for touch not to work. One users only was responding to only 2 touches u till flex was pressed back in. Try usin lg flashtool. Method. Set to board dl and itll take u to the minios where it does a touch screen calibration
Again prob not case. But ive seen it happen
Possibly digitizer failure. But knockon working is weird

Can you please explain the "Set to board dl and itll take u to the minios where it does a touch screen calibration " in a noob friendly way, there are a lot of lg flash tools I see. Also, no, I haven't dropped the phone or any water damage. It just stopped responding suddenly. Knock is responding smoothly anywhere on the screen. I have flashed the rom to stock, same issue.

I use the same lg flashtool as lg g2 and 3. Older version. On main menu of flashtool u have a few options upgrade. And board dl. If u leave it. It takes u to the old factory reset status 2. And stays there if u set to board dl its gives fac status 3 and boots what is called mini os. First thing u have to do is touch the screen for a calibration test. Its required before mini os finishes booting. Then reboot as normal. Its kinda hard to explain. Its how i reflash stock firmware back from the g2.
Its always worked so ive never upgraded method across 3 phones.
U might look in restoring stock lg g2 flashtool. And replace with g4 .tot and .dll
Also have to set in device manager set to port 41. When in dl mode
