Thats called Screen burn or Ghost Image or Image Retention.. Thats a common LCD issue. Some screen filter apps will help u little. If possible post your LCD model number here. Code for getting model number is
*#*#6484#*#*
Version Information and scrool down then see LCD
Are u using Gold version?

Don't use the phone display for a day and it should retain its original state. Also try to leave it in a moderate temperature during that time (20-30 degrees tops on celsius).
Mine does that on long gps journeys and retains full restoration as 5-6 hours of powered off.
Screen retention(ghosting or whatever....) is common lcd issue that emerge itself even more on higher temperatures. Just keep your phone (back and front) as cool as possible. Don't leave it for longer times on high brightness setting and be as less static as possible on the display images (this means to not keep the display on on a static image for long time) - this is valid for every lcd(TFT) device.

Galaxy S I9000 screen problem

Suddenly the screen of my "samsung galaxy's" seens to lost resolution, looks blurred and weak colors.
It looks like when changing the resolution of a monitor to display fewer colors.
Please can any good soul help me?
completing information
I also noticed that the button used to end the call, it seems
orange and not red as it should.
I restored the settings but not solved the problem. I'll try to flash the rom again to see if it works, but seems to be a hardware problem that appeared out of nowhere

That do not sound so good. Looks like a hardware failure to me. Do you have the screen on full brightness all the time? Perhaps you could try changing display density in build.prop and reboot. How long do you have your sgs?

Galaxy S screen problem fault
I am having the same problem. Vodafone Australia stock.
The screen has lost its clarity.
Actually, it appears as though every 2nd horizontal line has been lost - this is quite evident when you scroll through a list that has dividing lines (Eg. Scroll through settings - the separator lines alternate visibly as you scroll).
I've had the i9000 for just under 4 weeks and this fault occurred without any reason (not dropped, no water damage, not exposed to heat, etc). The phone was fine one minute and then the next, it became blurry.
The colours all look flat, the background is no longer crisp black, it is light black/grey as if the LCD that had its brightness settings turned up too high.
Also, tried upgrading Android to 2.2 (from 2.1) and that didn't help. This fault appears to be a hardware fault - you can see the loss of resolution when the Galaxy S logo appears when you first turn the phone on (before Android boots). Look at any curved text/lines and you will see that it appears with jagged lines.
Don't waste your time doing the factory reset, upgrades, etc... It is a hardware fault. I spent a bit of time running the screen through the LCD tests " *#*#0*#*#* " and downloading DPI checkers, etc.. The LCD test shows the solid Red, Green and Blue are ok, as was the dimming test.
The image looks grainy as if it was displayed in the wrong or low resolution. It looks like an old school CRT screen at VGA resolution - almost pixelated.
I have installed the Aries bootloader and the small font text displayed also looks grainy and very hard to read.
Have a look at the two images I've attached.
Real shame, I was starting to get attached to this phone.

First step would be to backup and do a factory reset for any major problem .

I already tried that and it did not help.

Don't waste your time. If you got warranty, you are going to get a new Screen or perhaps a new phone. Go for it.

Did you changed kernel? which kernel are you on?
I had a similar experience (not so bad) when trying some kernel with sharpness and color fixes.
You could try flashing hardcore's speedmod k13c Kernel, it also has some sharpness and color fixes but his work very good.
i don't have thi problem
I have the same problem, just purchased a i9000 four days ago, and it fail after 30 minutes of use .
It si very strange, because if i zoom a image, it will also enlarge the banding gradients (like if the image was low quality)
THe problem only appears wirh dark colors, strong colores dont have any problems.
this sounds like a display problem

Can we avoid Ghost touch and Burn in?

Hi guys I got my phone 3 days ago and I'm completely in love with it but I see many people complaining about ghost touch and burn in effect (ghost scream or dead pixels), mine is just perfect, I avoid using my scream light more than 50% or use while charging but I'd like to know if we can avoid those problems that seem to be a regular in Moto G4 plus because we need support here in brazil we are lost hah
So are there any suggestion on how to save my phone of having any of those problems in a near future? thank you

Actually this problems can not be cured, just reduced...
Check which type of Display panel does your phone have.. [ https://forum.xda-developers.com/mo...ntifying-lcd-panel-ghost-screen-burn-t3470472 ]

Frankly saying, i never had any of both, i don't know how those apps work.. but i read from many one, screen burn can not be completely avoided, you can just reduce the effect.. most of them says to use "bluelight filter or similar app at ~15% value.. it will reduce the display performance, but as it's new phone and don't have any problems you can see at what lower % it looks fine...:good:

So I have a boe panel. Been experiencing Ghost Touches when connected to home theatre or Charger. should I change my display?
Note - since the MPJ24.139-63 update, Ghost touches have been reduced to 5 to 10 percent while charging.
Thank You.

No need to change OR you can, no one will guarantee that you will not face same in new one too.. Just lock the screen, it is only we can do to prevent functioning unwanted apps / actions...

Ok bro. I will just lock the screen next time. Thanks a lot. It's a great phone. Pity we have to face such a pathetic issue. Also do you think I should return my phone? The only problem I have are This ghost touches. They ain't severe, just happens sometimes when I connect the phone to a charger. Do you think they will get severe in future?
10 days down with this phone and no problems. I avoid using while charging and always use low light, as for now its working, hopefuly as mine is made on 12/16 motorola fixed this thing up

Well I am happy for you bro. BTW what Charger do you use?
Have you tried charging with a different Charger?
I face the same issue of ghost touch (since the beginning of when I bought the phone)... However the only workaround I could get is that now I use a power bank to charge.. I guess it's the AC supply that's causing some grounding issues to ghost touch... power banks have DC output so I don't face any ghost touches with this..
OK, so I am unfortunately also a prey to screen burning , leaving screen burns all over the display during heavy usage.
solution : install blue light filter (hardy-infinity) from play store
After installing, select black colour as the filter colour option and set transparency/opacity to 3% ,. Done !!!! No more screen burns ! Enjoy??

They are prob apps you had their a really long time and you prob run you brightness up pretty high as most daytime users do causing the images to burn into the screen , unfortunately you will need to replace the screen itself off me phone time

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

Screen Problem

Hello,As always i have a new problem with my new HTC phone. at first i had light bleed on my top left corner of my phone.i persist my self not to attention to it.Now a new problem just appeared.When i use phone for a while,Some of the things and icons from the last app i opened,Left on the screen.It mostly showed itself when i go to a dark app or even scroll down my notification bar.It is like a transparency thing.i don't know what should i do,After that light bleed this problem really broke my heart.does anyone has this issue?
Thats screen persistence its a lcd screen just change the screen temperature too cool and it should fix it
Well i have not seen this on my u ultra yet but i have seen it on my old LG V10 which also used LCD. It usually happened when the phone is hot so most frequently in the summer or when under heavy load. Locking the phone and leaving it to cool for a few minutes always fixed the problem.

Just left the phone cool down for a while.
This defect name is Image Sticking.
I have same problem on U Ultra. It is a cheap phone with a cheap display.
All LCD panels has a certain degree of Image Sticking, but in this case is to strong and very easy to obtain.
This display from U Ultra is not good enough for a mobile phone.
I never saw this degree of image sticking on other phone, cheap or expensive.
