As you all might now, many models of the LGG5 suffer from image retention. There are some ways to fix it but wanted to create a thread which should probably get pinned for easy access.
Solution is simple, image retention is created by some pixels of our screen (normally at the corners of our device) when they are forced to brighten too much, we need to darken slightly the screen, lowering brightness does not help as pixels are still fully opened and this is what causes image retention. (I'm not too technical about this but I hope you understand what I'm saying)
An excellent app to fix is is CF.Lumen by chainfire. Rooted or not, it will still work.

Set custom filter and apply a darkening one to a value that fixes your problem. My issue got fixed with a value between 5-7%, I had a severe problem.
The only price you pay for this fix is around 5% max brightness which I certainly don't notice. Colors remain the same.

thanks for the explanation and detailed process, after doing this there is no image retention showing up again, and i am using blue light filter app having setting of 1800K at intensity of 2% and screen dim level to 6%.
works

Hi everyone,
I'm a former N1 owner and just bought a new NS i9020a from Negri Electronics and I'm finding a few funky things that I'd like to run by you guys. I'm suspecting that the phone might be defective, especially 1 and 2 below. Anyone else have these issues, or perhaps they are really non-issues?
1) My screen has pretty bad horizontal banding. It's most obvious in the notification pulldown, but is also noticeable with certain wallpapers, dead pixel test apps, etc. Please see screenshots below. Has anyone else had this, and do they fade away over time?
2) The galaxy live wallpaper has a layer of static "stars" or something above the actual spiraling galaxy. This layer kinda looks like stars, but some are splotchy/smeary. The galaxy itself also has a pink border/box around it too. I've factory reset twice and the same thing happens. Maybe my wallpaper is defective? See screenshots.
3) The screen in general has pretty yellow whites, especially in low brightness settings. I am not wowed as I thought I would have been with the SAMOLED screen.
4) When in the camera app, the picture doesnt actually take up the entire window. There are a few columns/rows of black pixels surrounding the picture. It's not centered either. See screenshot.
5) my volume rocker has a middle click, so there's up, middle, and down.
Banding:

Galaxy wallpaper:
Camera app:
i'm on an ns4g, and i have the exact same problems. its not big enough to bug me though. btw, the samoled is more known for their deep blacks than their whites.
I would get that exchanged asap but since you bought it from Negri you will hard time.
i have a i9023 and got exactly same black line in camera app, it just doesn't take up the entire windowi believe it's a "feature"
i think "middle" button in volume rocker is normal, cause every android device i owned it was present, sometimes when you press it, your system gets lagged for a while, like 5 secs, i believe it's something related to debug setting, also you can use it to disable power button in cw recovery (don't know why)
the rest of your problem i can't actually help, since my screen is not the same!
edit: when you change from photo to video in camera app, don't these lines/rows change at all?!
Camera looks normal, just like mine.
Banding looks bad though. Possibly defective display. If you have warranty, you should exchange.
AFAIK there is no Android phone with an eInk display.
eInk Display swap:
I wonder if there's a device out there with a modem that would be a good candidate to replace the screen with an eInk, or at least, sunlight readable display?
The last time I looked into this the graphics driver itself would probably need replacing too, making it much more difficult than a simple screen swap. Also I was unable to get find a donor phone with a screen size to match off the shelf eink displays and also sourcing an eink display was difficult too. I need to learn more about how displays work and how I can search to get a phone and screen to match. Any ideas on this?
Kindle:
Perhaps I need to come at it from a different angle? The old kindle is eink and Android... and it has 3G... but it's hard to hack with... it wouldn't be easy to turn into a proper phone. That I will have to investigate. Any other ideas?
NookTouch:
The NookTouch would be a lot of work to turn into a phone but it's technically possible. You could go hostmode, usb hub for mic/speaker/headset and add a USB modem but that's going to be messy. To do this neatly you'd be cutting up the Nook and would at least want a low profile way of connecting into the USB port. Plus charging might then become difficult, especially if trying to do the induction charging hack. I think other avenues are better to try.
I don't think that the old kindle is android based, and besides it wouldn't be ideal as it's not touch-screen
or you could go down the 50/50 route and follow this guide:
I use a matte screen protector and using an app like Cool Reader (since I'm on Android). I change the background to a moderate to light grey and the font to a dark grey about 25% -30% lighter than black. Turn down the screen brightness to about 75% outside and 45% in doors. Then change the font by adding fonts to the system fonts to a more soothing type face like "antipasto". Increase line spacing to about 125%-150% and margins to no more than 10pt on all sides.
See the above image for what this looks like. It isn't exactly like E-Ink, but it is nicer than staring at a bright white screen. This trick should work with any app that lets you tweak the text and background colors, on iOS or Android.

Agreed! I'd like this too. Samsung is letting their design team run wild without considering the advantages of the technology. Sad.
+1 I really though there was a setting hidden somewhere, But no. Black would have been great. Dont know why they though Blue was better..???!!?
I want black BG too.

Hey, I figured it out. I've attached the apk. You need to be rooted obviously but once you are, use ES File Explorer or something similar to replace the EasyOneHand.apk file with the one below. You should get the same result as the one in the screenshot.
The file is located in /system/app. Make sure that you rename the download below to "EasyOneHand.apk". The attachment manager added a 1 to the file.

Don't forget to backup your original and donate :victory:
I assumed it was something to do with burnin.
I.E. on amoled, black means the pixels turn off, so if you do the one-handed operation a lot, you'll quickly see an image burnin. with blue, you are using the largest of the subpixels, so maybe its a hue of blue to better handle battery drain (larger pixels need less power to illuminate to a certain percent, or there are fewer blue pixels than green, so less power needed to power, etc. could be a variety of reasons around the hardware alone).
I just figured there was a reason why it was a soft blue, and non-changeable. But then again, it could also be a simple matter of something that slipped through the cracks and wasn't even considered as an option people might like to customize.

If burn-in was a concern, then why use a white border that utilizes all the pixels? Why not use a thin light-green border with a mostly black interface instead of white. I think Samsung is just letting their design team loose without considering the benefits of the tech. Look at the phone dialer. Why is it all white?
So my galaxy s5 has been working great for the past month or so that I've owned it. I have rooted it and done some adjustments with the xposed installer, but I haven't flashed any custom roms yet or anything. So then today out of nowhere, this little stripe appears on my screen:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
So that's annoying. I took a screenshot on my phone and then moved it to see if it was the actual screen or just the picture being displayed on it. However, the screenshot shows no black stripe when zoomed and moved around so that the would be screenshotted black stripe wouldn't be on top of the actual black stripe. Then I restarted my phone, still there. I booted into recovery mode to see if it still happened when not opening the actual normal use, it was still there. Then finally I tried pulling out the battery and putting it back in, still there. I'm a little frustrated and a bit scared that I've already voided my warranty by rooting it and disabling knox. Also, the line turns sort of white when against a dark background and goes away when the screen is off. It's not the worst obstruction in the world, but the phone is less than a month old, so obviously I want it to be perfect. Any help that can be offered is appreciated.
I'm on verizon if that makes any difference.
Edit: I haven't dropped it, exposed it to heat or magnets or anything of the sort
It's unfortunate that you didn't post a full size, full resolution image. We can't make out any fine detail in your reduced resolution image. It would also have been good to know if the band is invariant in size as you make screen adjustments or display primary colours on screen. Or if it shows up in downloaded photos?
We are of course seeking a pattern or otherwise trying to narrow down the potential causes. Since we don't have much to go on yet, we can only guess, it looks to be a hardware defect. But there isn't enough information to be certain.
It would still be useful to look for a pattern in whether the band varies at all with different colours and brightnesses on screen. You can also use the dialer code *#08# and display red only, blue only, white only, black only, etc screens to get a better sense of which pixels are apparently contributing to the band.
Also try backing up the phone (to save your user files or installed apps), then revert to 100% stock firmware temporarily, followed by a factory data reset. If the problem persists it is all but certain to be a hardware issue. Claim it under warranty then if you can.

Hello,
I have a problem with my Axon 7 , it is not rendering red anymore. When I start the phone it is showing the colours correctly and just until the startup page with the collage is about to change to home page all the red is changed in muddy brown and stay like this. See attached pics. Does anyone encountered the same problem?

did you do a hard reset? Probably you could change the "color modes" over at screen settings, see if that changes. if that's not it look on developer options if there's an sRGB option and change it.
maybe downgrade to Marshmallow if you are in Nougat and then upgrade again? If you have an unlocked BL you could also download a full EDL image from the guys over 4PDA and flash it with MiFlash
Weirdest thing I heard about...
Your image seems to be broken so it's hard to tell what the issue is. But judging by the description do you have the Night Light setting enabled? Check first by going to
Settings -> Display -> Night Light (9th option down)
See if that's enabled or set to turn on at a certain time. This feature changes the color of your screen to an amber effect which might be what you're seeing? Sorry if this isn't related to your problem. You may want to re-upload your picture showing the issue.
I don't have night mode on my phone. It is a G version and now have the B04 on it. But the problems started with B02 so it is not the last update. I cannot attach pics but all the red colours are a muddy brown now.

Then do what I told you, it seems that downgrading to Marshmallow actually wipes everything.
I have done a hard reset and everything is just fine now.
