Hi, i always have this issue with MOTO G4 plus searched a lot about how to solve this Screen retention Problem some says Ghost Screen whatever it. I have also replaced the Display of the Phone but nothing done.
Then i got some information from the web about to change the RGB value of the display as for me it works at 240,240,240. You can change the RGB value of your display with the current ROM also. But i am using a custom ROM named [ROM][FINAL - 10/29] Resurrection Remix v5.8.5 [7.1.2_r29][athene] and changed the RGB values.
You can find the ROM details https://forum.xda-developers.com/moto-g4-plus/development/rom-resurrection-remix-n-5-8-0-t3507275 and you can change the RGB value to 240240,240.
I think the screen retention problem can only be resolved by changing the RGB values. As you asked for a stable ROM thats why i mentioned the ROM else the Color value can be changed in any Rom.

No, changing rgb values have no effect on ghost touch. That's a different problem.

so ghost touch is hardware or software issue ? I mean, if we use custom instead stock rom, it will fix it ?

Have a look at here https://forum.xda-developers.com/moto-g4-plus/help/real-reason-ghost-touch-issue-apart-t3700930
Reducing screen brightness can be a workaround, maybe.
There's another thread about ghost touch, have a look at.

Trinity P3600 Display Issue

Hello,
I've got a problem with the display of my brandnew Trinity. Where a pure black area should be displayed, the screen shows a black area which includes many little colored pixel (always the same) that doesn't switch off. With a black background setted, it looks like the milkyway, just with color. I couldn't say if this is a software or a hardware issue, because I have flashed some different ROMs before I recognized these bugs. After flashing back to the latest HTC release the output stays the same. I think the display is broken.
Are there any people with the same problem, or somebody with a solution?
I'm also looking for the original A1 ROM (including QuickGPS), if somebody has.
Greetings

[Q] LG G2 Cloudy ROM White Lines On New Screen After Screen Timeout

This is regarding a LG G2 with G3 cloudy ROM.
Hey guys. So my wife recently got stung by a bee, and subsequently threw her phone up in the air, and it landed nicely onto the driveway lol. Needless to say, the screen shattered. So i ordered a new screen online, and after installing it, it works fine upon power up, but as soon as i sleep the screen and turn it back on, the screen it all white with lines and is not functional. I also noticed that the ear speaker was not working.
I requested a replacement screen since i figured it was a defective screen, although the replacement is also doing the same thing. So i put on the original screen, and i am able to sleep the phone and awaken the phone, without any issues.
I read online somewhere that this could be an issue with the ROM? If that was the case, wouldnt it effect the original screen as well? This is not my video, but the phone does the same exact thing:
Apparently i cannot post any outside links. But basically the guy turns the phone on, everything works fine, as soon as it times out and he wakens the phone, everything is white with lines going up and down.
Any ideas what i can do to fix this? Quite frustrating!
thank you!
anyone?
That's a kernel issue. These phones are made with two different types of panels one is JDI and I don't remember the other. I had the same thing happen once. The newer kernels have an auto detect built in to flash the correct type. You didn't mention which version of Cloudy you're on, so I can't tell you exactly which kernel to flash. In recovery flash the Dorimanx kernel appropriate for your version KK or LP and it will fix the issue.

No, I've never seen that problem. I haven't heard of anyone having that issue either.
JDI display
I also have that problem.
I've tried the Panel Swap zip to change the panel to JDI, but it doesn't Work.
I also tried different kernels. If the screen goes to sleep the white lines reaper.
Please help.

Does Android N update fix Screen Burn/ Sreen Retention Issue?

I have heard that OTA for Android N soak test is catched and many people started using it.
Will updating to Android N fixes this issue?
I read somewhere that it is a firmware issue and LCD screens wont burn.
No,The problem still persists.

So we must have to replace the lcd screen as a fix?
There is no other way?
The firmware in the LCD driver chip needs to be flashed. That's not part of the OS installation.

How ?
We won't be able to do that ourselves. Although we can still visit the service center for the same. (or just use BlueLight filter at 5% black/set the rgb values (needs root))
Clearly, lcd color recalibration via kernel params can mitigate this issue.
However, it looks like Moto simply doesn't care. They could've patched this in any of the OTAs they've sent out! :/
I doubt that RGB re-calibration is working on all the affected screens.
And BTW, you don't need root or kernel access to install a blue light filter:
https://play.google.com/store/apps/details?id=jp.ne.hardyinfinity.bluelightfilter.free&hl=en
I'm not saying it'll fix it for everyone - rather mitigate or lessen the issue. They could at least try it.
A blue light filter is a suboptimal solution - they render a blue layer, which consumes extra power and gpu render cycles, leading to excess overdraw.
This is a well documented issue with all such apps, it's the only way to do it without root/custom-kernels.
The system level solution adjust the actual color render values, which has zero overhead and looks much better.

Have a look at the guides section, there are workarounds already available :good: otherwise you can let it replace again by the service center
Replacing the screen does nothing, it's just a DUMB move from service technicians that don't know better.
I agree, look at the guide section, but be aware, for everything there you would need first to unlock the bootloader with the code provided online by Moto/Lenovo. In most countries (exception EU) that means you lost the warranty (if you still have some left). I see you edited that you are using already a customized ROM, so that doesn't apply.
Install a custom kernel that allows setting of the display's RGB values lower, so they don't "saturate" the LCD (it's screen RETENTION, nothing gets "burned").
For me lowering the RGB values at 240,240,240 works fine.

Well the service centre near my place are kinda knowledgeable,they told me to wait for some days as theu had sent back the whole batch of displays they had of g4+ stating that they have this issue.And the new batch they got was the boe display (this display dont have screen burn but has Ghost touch which i dont think is happening till now in my device).
That's stupid. My display is BOE and it developed the SCREEN RETENTION (there is no "burn" on LCD) after the Nougat update (fixed it with custom lowered RGB). No "ghost touch" here.

U sure?
I guess I remember wrongly, it is LGD. However, it worked fine until the Nougat update. And I saw numerous people stating that their LGD didn't have screen retention on Android 6.0 (in that thread).
I had this issue for a long time. The only workaround I came across some days back (while experimenting) is the following one:
1. Install Twilight app from Play Store.
2. Open the app.
3. Reduce the intensity to 0 %
4. Set Screen Dim to 10% or 5%. It works in both of them.
5. Change Filter Times to "Always".
After some time, the burned in icons will disappear and won't appear again.
When installing any app from Unknown Sources, just pause Twilight first, install the app, and immediately turn it on again.
The best thing about this workaround is that, it won't turn your screen reddish or yellowish. And the difference is negligible. I've tried this on many other Moto G4's and it actually works!
The best way to solve this problem will be a kernel adiutor
Where screen rgb values can be changed. Changing them all to 240 and decreasing the screen value to 121 solves that for me

What is the real reason behind the ghost touch issue apart from the charger issue ?

This might not be the new thread regarding the Ghost touch in Moto G 4 plus but I just want to know whether this problem is behind the hardware or software? I tried many solution but non of them give a little bit of hope
1. change the battery optimization on Google now launcher and System UI
2 . Turn off the adaptive brightness and keep the brightness level less than 1/4
3 Turn on the force GPU rendering
in the indoor phone works alright and when i take out the sunlight it start to ouch Screen Ghost Clicks and Flickering
what will be the real solution? do i need to change the LCD display or wait of another update if it regards the software issue
