new phone is not working properly - lg g4 (screen issues/power button) - G4 Q&A, Help & Troubleshooting

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.

[Q] Screen wont turn on after it turns off. ATT Tilt 2

Everytime I boot my phone up, it works fine up until when the screen goes into sleep mode. Once it goes into sleep mode I cannot turn the screen back on, it stays black. The keyboard, end and answer key lights show up when I press the power button but the screen just stays black no matter what button I press.
I end up having to either take the battery out or using the stick to press the reset button on the side in order to get the phone to where I can see the screen again. I have adjusted the settings to where the screen doesnt go into sleep mode and the screen just stays on but that drains my battery. I want to be able to have my screen go off so I can save power but if it goes off it wont come on again until I reboot.
I have done a hard reset. This problem started happening to me when I started using the Energy Rom but I've even flashed different Roms and the problem still exist.
Somebody please tell me what's wrong! I need help! This is a big annoying problem to have. Thanks.
is this problem occurring when you slide the keyboard out?
i had the t-mobile touch pro2 with this problem.
the screen would die when the keyboard was out and not come back.
if this is the case, what i did was...
well. obviously not open the keyboard fully.
but if i accidentally had.
instead of pulling out the battery, i waited...
till the screen 'naturally' went to sleep.
than i would pull out the stylus or press power button
and the screen would come on.

Yes the problem still exist even when I slide the keyboard out. Once the screen goes off, that's it....pressing the power button to get it out of sleep mode, sliding the keyboard, I press all buttons and nothing works. The only thing that "works" to get the screen back on is removing the battery or using the stylus to press the reset button.
When sliding the keyboard out the keys light up but the screen doesn't come on, also pressing the power button lights up the end and answer keys without the screen coming on.

so. whenever the screen goes out, period, you cant get it back?
or the screen goes out and cant get it back once you slide the keyboard out?
if it is only when sliding out the keyboard...
try not opening the keyboard fully on the right side.
on my rhodium, after that point, the screen goes out.

Yes, period. Also, you know when you put your face to the phone during a call and the screen goes off so your face wont press anything on the screen? It doesn't come back on from that either once I end the phone call, it just stays black. I'm assuming you don't have any other suggestions. This Sucks

This has to be a software issue but I don't know where to start. I'm surprised nobody else has encountered this problem. I've grown frustrated of this issue because I don't understand why it's doing this. I have had the phone for almost 6 months only dropping it once 4 months ago and it wasn't a strong damaging drop that would affect anything inside. I guess I'll just have to go last resort and call warranty to swap the phone out. Thanks for the help.
Same problem

My phone also dos not come back on, when I put it in out the sreen with the power button on top, or when the phone goes to sleep. Nothing can put it back on(opening te keyboard, pulling out the stylis, presing the answer-, windows-, back- and end button). I and up using a music players too keep the phone busy what's makes it operational. Cant really remember when this started happening exactly. My phone is at the moment loaded with a standard ROM. I used too have a custom ROM.
My TP2 does this too, although I only encounter the problem sometimes when someone calls. I answer and put the phone next to my ear, the screen goes black as it should and the phone just dies. I can't hear what the other person is saying and the screen wont turn on anymore. I have to take out the battery to reboot.
set light sensor to manual in settings. You have some bad or fragmented code causing the problem. Pretty common actually, many different reasons, but usually either a bad light or proximity sensor or software issue. Setting the sensor to manual should do it, if not, hard reset and allow the phone to fully set up before touching it, to allow full customization process to complete. Search my posts on SOD (sleep of death) for more information.
Funny this was brought up. Now im worried I just dropped 250.00 and have a new one coming.
Mine started with the ear piece quit working. couldnt hear anything except on speaker.
Anyway I started having the screen issue over a month ago, only way to get it back was soft reset with the stylus. Also when the screen was lit, I couldn't hit the power button to turn the screen off. At times the screen would be on 24/7 and I just dealt with it. The times when it decieded to go to sleep was when I needed the soft reset. Well long story short I forgot my charger one day at work and the battery died. after pressing the power button for hours with no response, moving the screen in all diffrent directions as I pressed the button.It came on once after hrs of messing with it. Well today it died again and I am fed up with it so out came the tools. Once I opened it up I noticed the ribbon that feeds the screen from the mother board was worn and torn. the ribbon slides everytime the keyboard is slid out and it rubs on both sides of the phone. I thought maybe mine was just a fluke and was installed wrong considering the phone being 10 months old but now I read this and see maybe its a common problem. The cheapest I could find the Ribbon was 56.00 so I didnt want to chance it not being the issue.

[Q] Touch Freeze Than Goes Back To Normal After Hitting Power Button

Hello! Okay short and simple. Did a new screen replacement. Using the touch screen all of a sudden my touches don't register. Only the menu and back buttons but nothing happens. Than if I hit the power button once to turn the phone to sleep mode and wake it again I can unlock my phone and start off where I left off when it froze. Anyone have this problem and know what it is?

I have the same issue. Had the glass replaced and now the screen becomes unresponsive, hit power to sleep and back and it starts working again. Did you find a solution???
Was just the glass replaced, or was it the entire assembly?
If it was just the glass, was LOCA used?
If no loca was used (only the double sided boarder tape), the digitizer may be building up a static charge interfering with its function.
If loca was used, it may be a partially botched repair.

LG E980 e98020h camera turns on using volume button while phone is locked.

My wife asked me few times, honey, why do I have hundreds of black or useless photos on my phone? At first, I thought our smart toddlers were playing with her phone, but they are not smart enough to unlock it using the invisible pattern lock! So today I decided to clean the sticking volume buttons from juice and I pressed Volume up for more than 2 seconds and the phone vibrated for half a second and the camera turned on.. WTF? So I turned off the screen using the power button and pressed the Vol Down and same thing, phone vibed and camera came on but the photo icon has a lock on it.. So, I checked my phone running e98010k but it doesn't work, my phone doesn't turn the camera on at all.. Can anyone help me disable this feature? An no, case won't help and she's not gonna have it on a belt clip either, thanks.

[V500] Screen unlock/wake up issueI ??

Hello
I was on vacation and had v500 (installed with Slebits Validus LP ROM) with me.
Something went wrong and I could not unlock screen or wake the G pad with power button, just didn't happened. The home screen showed for a second, than it went black and couldn't wake it up with power button or double tap the screen, nothing. But I could enter TWRP with button combination (so power button works). I flashed different kernel, but nothing changed.
So when I came back home I flashed another CM12 ROM, but the same thing.
When ROM boots, home screen shows for the second, then goes black and cant be unlocked no mater what.
Is this some kind black screen bug? Wrong bootloader?
Need help, please... thx for reading
Are you using a tablet protector with a magnet lock in the cover? Try taking it off to see if the cover is causing interference.

Thx for answer, but no, I have no cover.
Couldn't find anything similar on internet, so I reverted gpad back to stock.
Surprise, there I also cant unlock the screen. But when I did button combination to initiate factory reset, on/off button works every time.
Ill sent it on service, its still under warranty. We will see...

Screen turns on again after lock

My G4 runs on MM 20D and sometimes I have an issue that the screen turns on again after I lock the phone.
Also the same if i want to turn it on.
It's like I press the lock button twice, but I don't.
Same problem here.i doubt thst its a power button issue.donno exactly.
Have this problem on mine too. Thought it was a sensitive power button but does it when I double tap to sleep also. Do you use lightflow? I found a setting in there that was turning my screen black after I woke it immediately. Almost like the proximity sensor was covered but obviously it wasn't. Got that problem fixed after scouring for solutions but this one still plagues me. I'm on Genisys LP, but had it on MM too ( had to revert cuz random reboots made my phone unstable)
