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_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"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.

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.

I have major display problems on any CM based ROM with crazy jumping and unreadable screens.
I have tracked the problem to the display of white lines. A screen shot is OK, so its hardware - either the Adreno200 GPU or my screen.
Problem Description:
Lines (pixel lines that is) containing a significant amount of white randomly do not display. As a result the display "scrunches up" with a gap from the bottom. Any background to the app, and sometimes the desktop will display in the gap at the bottom as it has not been written over.
Note the "bottom" in this context is the button end of the phone, thus rotating the phone leads to different screen areas being affected.
Affects all the CM ROMS I have tried, with the latest CM10.x ones being the worst. There was no issue with the stock LG ROM.

Coloured triangles produced by "OpenGL Demos" app are OK
2.
White Triangles loose lines and scrunge up. I used the Demo prog as the code is the same, just a color change!
3.
Screen shot, so not a software issue. What they should look like!
5.
Google Play. Unusable. Note hte white background is OK. It just seems to be items that are layered onto the screen.
Apps with black backgrounds and grey/coloured text are fine.
What have I tried?
I have tried messing with OpenGL HW settings with no effect.
I have messed with screen brightness.
I have tried various ROMS.
I tried moving processing from the GPU to the CPU, but that completely messed the display, and I had to re-install the ROM
I haven't tried altering the refresh rate from 60hz, but cannot find if this is possible. I think its a refresh problem, but not sure. Its almost as if the white lines are sent faster than the screen can handle and they are missed during the display phase.
The other theory is that the GPU does some special acceleration cleverness for white areas the screen can't handle.
Any ideas?
Any Adreno200 settings I could try?
Any bridges nearby I could jump off?
p.s. Photos taken from the Optimus Nexus Me port here:
http://forum.xda-developers.com/show....php?t=2397696 not that it matters which ROM it is.
Obviously, it's not "soft" problem, it's a "hard" one, replace the screen.

That was kind of where I was heading, but I was concerned that an aftermarket screen would have the same problem. This screen was fine with the stock ROM, so was hoping for a magic setting change.
Thanks for the response. Really wanted to run your Zoe ROM, but that was worse.
To be honest, I wouldn't replace the screen on this phone anymore. It isn't worth it anymore.

Hi there,
My phones touch screen broken last month, I ordered a new digitizer with frame from China, I replaced broken screen carefully, then I turned on my phone, but I saw white lines on the screen.

"lightbox_next": "Next",

}
Then I saw this post http://forum.xda-developers.com/showpost.php?p=52414185&postcount=122 I thought it may be a kernel- digitizer incompatiblity.. I rooted my phone first time in my life, then flashed that kernel in the post, then phone is completely bricked.. now I see a black empty screen, it says "fast_boot started" etc. I googled and I saw some posts however nothing solved my problem.
I believe my phone is not bricked since it gives a response of black fastboot screen.. Can you please help me? I am a total Android noob, please don't just say "go to the download mode" tell me how to go to the download mode as well you can share links as long as they works..
I hope I can make my phone work again.
Finally, if I managed turn on my phone, can I really make the white lines disappear with software tweaks or my new touchscreen hardware is broken?
Thanks in advanced,
Eray
anyone?
I don't personally flash non stock roms, but if you read on the post with those type of roms a lot of them talk about a "JDI kernel" for the white line issue... Once again I have not personally seen it so I am not sure if that is what you have pictured, but it is worth a shot... Go to the forum where you got the rom you are on and look for a JDI kernel..
Reading your post it sounds like you had never installed a ROM until the screen issue arose with your new screen, if that's the case then redoing a ROM won't work for you as far as fixing the lines. Most people have found that issue to be permanent anyway and there is some debate on whether or not it is a flaw with the screen itself. Check my profile, I have a thread I did when I replaced my screen. It covered where I got it from and had a link for a great how two on youtube. If you get the date one it'll be a lot and not job. Your phone isn't bricked BTW. This forum has a wealth of knowledge on how to go about anyhing you wish to do. Whether it is to fix an issue or tweak to your hearts content. The search tool is your friend. Feel free to scroll my posts via my profile too. A while back I helped someone and covered a lot of different steps. If that doesn't get you any where let me know and I will see what I can dig up

I had the same problem last night. The solution is:
do you see that little tongue at the bottom of the screen full with resistant?
That little thing is sort cutted by the white antenna connetor when you put it together.
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.

100 percent working for me.

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
