[Q] Green Dots Screen Problem Galaxy S4

I bought a Galaxy S4 i9505, and update it to the latest firmware 4.2.2. After 7 days of usage, some green and black dots appear in the screen and they are blinking randomly on the screen (Please see the attached screenshot. The site uploaded the images in very low resolution and think the dots cannot be seen).
I think is a software problem, because it also appears in the screenshots.
Did anyone see this problem before?
P.S. I have already done a factory reset but the green dots problem still remained

I think that u have Deadpixels. Try a pixel test from the app store.

Thank you for your quick response. I don't think they are dead pixels because they are appearing in the screenshots. If they were dead pixels they will not be able to appear in the screenshots because this is a hardware problem. Isn't it?
i.e Think about your computer and PrinScreen Button. If you have a dead pixel on your monitor it never appears in the print screen picture.
Also, these dots are randomly produced anywhere and they are blinking all the time.

Yep that was a derp reaction of me....sorry can't help u further. Did u tried flashing a rom?

Hi there,
I have the exact same problem currently running 4.3 XXUEMI8, however it has been a problem since I bought the phone brand new from stock.
Refer to screen shot attached, where the pixels are clearly visible at 1:1 zoom.
The green and red pixels are also very visible when viewing YouTube videos or anywhere that is displayed as solid BLACK or WHITE.
Did you ever find a resolution?
Here is a link to a full resolution image (XDA image uploader masks the pixels on resize): osiris-developments.co.nz/temp/Screenshot_2013-10-09-15-59-39.png

ohh! I am so sorry about that. Exactly the same problem. Also, when I took pictures, they were fine, but when I made video calls, I saw the dots to my pc screen. I thought is like a VGA problem. If so, the damage is very huge, and maybe the motherboard needs to be replaced.
I didn't find any solution, so I sent the phone for a repair. A month passed, no news yet. I suggest you to return the phone as soon as possible!!
When I have news, I will write back to you.

Just to follow up on this, phone was replaced under warranty. Samsung did not specify what exactly was repaired, however it was turned around in about 3 working days.
I have since moved to the G900F anyway

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.

Weird issue on the screen

This issue appeared after I install (via fastboot) the latest version with the December patch. Basically, what's on the top line of the screen appears on the bottom line. This also happens with LOS 14.1. Has anyone had this problem? What could it be?

It looks like the screen shot doesn't show the full screen. I've just uploaded some photos. Please look at the top and the bottom lines of the screen in such shots.

It doesn't seem to be software or ROM issue,
Still, If you are confused and think it's software issue,
Take screenshot and move it to another device, if it's shown alright in other device, then ROM/software is okay..
For hardware issue,
Display looks good in photo,
may be disassembling and reassembling display can do work, but there is many things inside hardware, can't say..

I did what you've suggested and the screenshot showed up alright in other device. I've just noticed that sometimes the issue disappear. Thanks!

I don't know if there is a connection or it was a coincidence but the issue appeared after I turned the OS of my computer from 32-bit to 64-bit. I'll try to flash the stock rom on another computer.

I've just find out that if I put the brightness in the maximum (or next to that) the issue go away. ?

I am facing the same issue. My Moto g4 plus is running on Android nougat. The top lines appearing on the bottom of the screen (below the navigation bar). I don't think it's a hardware problem because the lines disappear automatically and again reappear after some time. Pls help.

Same issue here....

There's this app on Playstore called Screen Overlays,
I made a white stripe on top of the status bar and one on the navigation bar,
And the issue,which usually is white stripes on black screens is kinda solved,
It will be a temporary solution,
Since the Oreo update will prevent overlaying apps from being active

awkward problem with s5

Hi everbody, i had bought a s5 g900f, 2 week ago, for my brother. So he said that the Phone had problems with wake up after standby and that the remove the battery and got problems with booting the s5. The booting font colour chance from white to yellow. I make a video to explain my problem

The font color issue sounds like a video card issue (not sure if it is called something different in the phone world). The wake part could be something in the same physical area as the font color issue and both could be broken, or burned out. You could look up some ways to replace the motherboard or screen to see if that maybe an option. Depending on the price of the replacement parts sometimes it is just better to get another phone.

OK thank you very much, but is comes up sometimes, not always, then he's to buy new phone.

Probably not. Might check the flex on the screen. But thats about as far as you can go

Ok thanks

i agree with @TheMadScientist. if you look at the thread right next to the OPs (well, it was at the time i wrote this at least) a similarly described problem is extant there. Its likely the ribbon cable and not much you can do about it
