I have MOTO G4 PLUS 2GB || 16 GB of indian Varient with XT1643.
After using the phone around 5 months i have such "SCREEN RETENTION" problem. I have also replaced my DISPLAY from the SERVICE CENTER but the same problem in the new Replaced DISPLAY.
Now I am using Custom Rom like Resurrection Remix v5.8.3, Pure Nexus ★ Substratum.
So Is there any solution For This Issue?

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

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.
Iam planning to buy moto g4 plus, i heared there were 2 batches with 2 types of screens LGD and BOE . please tell me how to check the screen details of this mobile. and also please tell me what should i check before and after buying this mobile as this is highly controversial model. Thans in advance
Install DevCheck System Info. Search for the 'Hardware' section, and then scrolll down till you find "Panel", it displays which screen do you have (BOE or LGD).
You shouldn't check anything else, since the only bugs of this model come from the screen (always can exist an exception, like in every smartphone).
Short story:
LGD = possible image retention (can be fixed).
BOE = possible ghost touches while it's connected to a PC/Charger (can't be fixed).
Thank you
Thank you very much ..
Sir,
I just found that my screen is an LGD . should i worry about image retention ? is it common in all devices ? (my device mfg date - september-2016).
Is there anything else should i be careful at or worry about ? please suggest..
thank you

Sir, I have a BOE display. As per your post, it can't be fixed. But will it be replaceable for free, if I go to the service centre?

Yes, it should. Since it's a manufacture fault recognized by Lenovo. Some BOE screens will never suffer from this fault, is not my case, mine has ghost touches when is conected to a PC, since the zero day, but it is not big deal for me, obviously is a clear failure and can be very annoying for these who need to use their phones conected to a PC or wall charger (in my case i never faced ghost touches while is connected to a charger).
@pinke93
In the case of the screens made by LG, the image retention can be corrected setting all the 3 RGB values to 240, you will need root for this. Some people uses a blue filter app from the PlayStore that does not requires root (i didn't test this method).
I "fixed" a normal moto G4 from a friend, with LGD screen doing the RGB value re-setting.
You should not be worried about something else, and is not a certain that it's going happen to your device.

Thank you very much. I agree with you. It's not a problem at all since I do not use my phone that much while it is charging. Moreover the turbopower technology gives me at least 80% charge in nearly 1 hour or so. But in emergency cases, say during doing a phone call, sending important messages, when the ghost touch starts popping up it is indeed really annoying. So as per your advice, I will have to go to the service centre to replace the display panel. And by the way I have rooted my device on the very first day I purchased my device.

Same here haha, i bought this device because my Nexus 5x die, that model has a terrible design failure (same as LG G4), suddenly it went turned off and never could relive it (hardware break: the welding that holds the CPU attached to the mainboard get broke). So, the ghost touch issue for me is literally nothing.

Yes. Despite packing some decent hardware, the Nexus 5X always had these problems. Even some had filed a lawsuit against google. But I don't think its entirely google's fault. It was the fault of the OEM's, and LG (for Nexus 5X) and Huawei (for Nexus 6P) faced lots of criticisms from the customers.

Thank you very much sir,
But, I dont want to root my mobile . iam not a techie ,not good at this kind of stuff, so dont want to void my warranty... as you suggested i think colour filter apps might work.
And, Incase if i get this issue in future, can i request the service center to change my display to boe ?
when i connect my earphones to moto g4 plus, its not showing any icon on status bar ( headset icon that we generally see at the top ), please tell me how to get it.
Thank you once again.

The company is bound to replace your screen under warranty
Also you wanted headphone icon in status bar
For that swipe down from top on home screen and long press on settings icon you will see it rotating then leave it. You will get a toast notification that system ui tuner ....
Then go to settings you will see a new section at bottom called system ui tuner under that you will find status bar and then you can select icon to show
Thank you @ Sobhan Bhuyan.
will try it
In G4+, Many G4+ Having BOE Panel reported Ghost Touch Issue. Motorola recommended to Replace Screen still Few Got Same BOE Panels and Some Got LGD which was prone to Image Retention.
So I would Like to Ask, Any Member, Who Flashed ROMs and Got their Issue solved.
As Many Times, Developer With some tweaks are Able to Solve, And Qudos to Developers for these Hard Work.
But Need confirmation, As I wanna Flash Something Stable, as My Father will be Using It from Now.
You may try these option

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.
Does anyone know how to solve screen burn-in issue? I didn't have this issue when I purchased the handset. It started all of a sudden. And now no matter what ROM and what android version I'm on, I always see the shadow of last used app (even if I keep the app open for 2 minutes). I am using Gold varient (64GB) handset.

From other threads there are two screen types and they appear to have moved to a new screen type that is less likely to burn, if you can, get the screen changed under warranty. The new screens are not quite as warm (more white). I have the new screen type and am happy with the colour.
I dont know if its the same, but i had a similar issue, where recent Apps that i used for some minutes (e.g. Whatsapp) slightly burned a shadow into my home screen.
I solved it by changing the 3 RGB values from 100% to 95% at Settings - Display - LiveDisplay - Color calibration (then restart phone).
Hi people,
Im sure most are aware of the flicker in j7 2015 model. I have both j7 2015 and j7 2016.
It was last year when j7 2015 got marshmallow update. Within few hours, the backlit went crazy. It was impossible to dim the screen without seeing all disco pink lines.
There were claims that it was fixed but i still have this issue. Samsung service centre said no display available and warranty period got over this way.
Now just a few minutes earlier, i faced the same isssue in my j7 2016 model. The screen became dim all of a sudden. On closer inspection i found every alternate pixel line was missing vertically. It tried to turn off and on the screen a few times. Then the issue became severe and i was seeing all pink screen. I could barely see the text on the screen.
I had ampere installed and saw that the phone was using over 970 ma of current. So i switched it off and tried after 5 minutes and nothing changed. Twrp, offline charging and holding power button with battery out didnt work either.
I kept on increasing and decreasing the brightness to max and min. Some times the flicker stopped briefly and i could see perfectly. After about 30 minutes of struggling the screen became normal automatically.
I started typing this story when the screen got back normal and it hasn't done wierd flicker till now.
If you face any issue like this, please share over here.
Im also sharing this with samsung so they may or may not try to investigate. They are leading manufacturer of oled display and although the display is fine, im sure their driver circuit have some flaw.
Screenshots , the white one is for low brightness. It goes reddish when brightness is high
I managed to fix the screen by replacing the capacitor array used in the screen.
I did some research and found the 20khz PWM singal used for the screen was out of sync. There is a clock pulse that is controlled by small capacitors to keep it a square wave instead of sinusoidal.
Wont talk more about what and how that works, its there on the internet, just google pwm brightness control circuit.
The capacitor used are either cheap or not within specification or maybe even completely of wrong values.
PS. I know how to handle hardware and soldering, make sure you know what you are against.
Before and after screens. Although i got some scratches on the touch panel, i saved a few bucks in my wallet
Used root dim tool along with team viewer to handle this.
Since i dont have a technical specification for this circuit, ill be doing some more research to fix it properly.
Wow!!!
