Why does my LG G3 screen flicker and fades to darkness?

[dancing-bass]

i have tried the paper for a week and it worked fine
but now nothing works

The paper will compress over time and become less effective. I have to change my paper about once a week as well

Just to clarify: That s mean you still have the issue with the CM rom ?

Thx

Negative, less issues when on CM overall. ROM reduced most of them changing the paper is just to make sure. When I'm at work I need my phone to be reliable

LG have now arranged for the collection of my G3. Although they don't want the battery or back cover. DPD will pick it up this week at some point. I have no documentation or anything. I assume the DPD guy will provide some? It all seems very un-organised. It took me three calls of me requesting a repair to get to this stage. Not very impressed at all with their customer services.

Anyone in the UK sent their phone to LG for repair? Are they good/bad? anyone?

Re: HELP - LG G3 Screen Flickers and fades to darkness

Throwing out a theory, because I still haven't nailed this down.
1) heat definitely is part of the issue. I experience more screen issues when using my full body case (TPU material) than I do when I'm using a bumper style case with no back on it
2) weak battery or poor contacts. Although the battery still holds charge reasonably well, I also have less issues if I have something at the base of the battery wedging it firmly against the phone contacts. I make mention of this for one reason. Some automobiles are very sensitive to voltage. If the battery contacts are slightly corroded it can cause the vehicle not to start, or very hard starting. This in turn wears the battery extremely fast, which just makes the whole cycle start over. Happened to my brother and a friend.... Anyway I'm wondering if a slight drop in battery voltage or amperage would cause issues within the main circuit board or connectors?

Anyone else doing their own troubleshooting?

On my side, I was not able to find the reason why sometime it will work during 5 days, and sometime I can't use it for more than 2s.

I used piece of gift card instead of paper but inexorably I have the issue : for this reason I don't understand why on your side, when you change the piece of paper, the phone can work again.
I noticed also that my phone can become very hot, close to the camera. Nevertheless even if I switch off the phone during couple of hours, I still have the issue.

I'm waiting feedback from at least one other user about the CM rom before I try myself it.

i dont know what else is wrong with this.. ive been changing paper for more than 1 month every 5 days but now seems like this method is consumed.. i even put a small coin . it worked for more than 1 week and i thought that coin would hold it but nope ,still the same.. i dont know whats wrong... anybody here changed the battery or downgraded to 4.4.2 ?

I'm running CandySix ROM which is non-stock Marshmallow and still having the same issues, getting worse if anything. The paper trick doesn't seem to work as well anymore and I cut a a piece of a gift card and put it on the bottom of the battery, also doesn't seem to help. Incredibly frustrating to have such an unreliable phone

Edit: Does anyone know if changing the battery has an effect? I notice that when I'm charging my phone and try using it, I don't get the flickering.

I sent my G3 for a repair as I had the same problem as everyone else here but they sent it back because I "rooted" my phone and it's not under warranty if you try to modify the software. They only told me this when I got my phone back after 1 week. They offered to fix it for an additional fee but screw that!

I did the trick with folding a piece of paper and placing it on the camera connector (when you open up the phone) and it seems to be working fine for me for now.

Yet another update. Custom ROM doesn't solve anything. I'm back to square on with the issues. Seems the only lasting thing is swapping the cardboard or paper frequently - and even that isn't guarenteed to work reliably. I even tried this:

with no improvement. It's gotta be a power/short circuit somewhere. Thought it was software but ROMs don't solve the issue. Possibly a bad firmware/driver from LG, which is possible - ROMs wouldn't change the firmware or driver software because that's core operational stuff.

anyone else got ideas? I'm running out of them!

Hi last week i have same problem also. i try downgrade to 4.4 and try paper thing i didn't work out

i think the only way is to change the motherboard and get a new one... seems like this problem is running a lot to G3 users....its a pity cus its a great looking phone... ive tried papers changing them for more than 1 month.. it lasted only 1 week then again.. now its ****ed up.. even changing the paper doesnt work anymore ... if u have any other solutions except of changing the motherboard pls update us bro

 

[drpooply]

Stock here. Regardless im more inclined to the hardware malfunction school of thought. Maybe some cheap solder on the mb?

Bump to bishop, i agree 100% with your sentiment

I agree. Seems changing the motherboard may be the only solution. I depend on my phone daily, so I got a Galaxy S4 as a substitute. If I decide to replace the motherboard I'll update. For now I'm going to enjoy using a reliable phone again!

 

[Hydao]

Funny. I also bought a S4 for the same reason last week.

 

[The_Huffster]

I have the same problem.

Replaced the screen, same issue.

Upgraded from 4.4 to 5.0.1 stock rom, same issue.

Used a custom rom to 5.1, same issue.

Custom rom to 6.0.1 marshmallow, same issue.

Most definitely the logic board.

 

[salieri_legend]

I am having the same problem.
Hope someone will come up with the solution very soon.

I have been dealing with this issue of the screen fading to black for the past month now, and it started right at about the year and-a-half mark of using this phone. It's pretty upsetting when I still have 6 more months left on my 2-year contract to pay off this phone, and the problem is some sort of hardware issue with the motherboard (Or at least that's my assessment after reading this thread). After following this thread for the past few weeks, I finally decided to give my input/solution to see if what I did to my phone possibly works for anyone else.

I don't know if anyone else has tried this or not, but I did this and my phone has been working perfectly for the last 4 days in a row after getting progressively worse (putting paper next to the camera and over the battery seemed to help a little, but then after a week, my phone was barely working at all). 5 days ago, In the developer options I changed the, 'Background process limit' setting to 'At most 1 process' for one day, and then I changed it back to 'Standard limit' the following day. This seemed to drain my battery the day I had it set to 'At most 1 process', but the next day I changed the setting back to 'Standard limit', and my phone started working completely normally again with no issues.

I waited a few days to post this to see if the problem started back up again (I've been dealing with this for an entire month), but so far so good. This might not be a solution for anyone and maybe my phone started working for some completely unrelated reason, but I thought maybe someone would want to try it, as it is pretty easy to do. I had 2 pieces of paper in my phone for the last couple of weeks, but it didn't seem to make a huge difference. When my phone started working 5 days ago, I left the paper in my phone, just in case if that's what was helping, but today I took it out. I'll post again if anything changes, but as of right now, my phone is still working. Hope this helps someone!
