hello to all,
So I've recently noticed this happening on my mi5 32GB variant. Whenever I close an app, after using it for sometime, a diminished part of that app remain even after closing it.
for example, if I use FB app for sometime and when I close it and go to homescreen, near the upper part of the screen I can see the diminished part of the FB app ( the upper part of FB app) even after closing it.
This can be viewed better if I go to recent apps screen. Since it has a greyish background the image can be viewed better. This is more prominent in the upper corners of the screen, but it also visible on the lower corners as well.
This happens when the phone becomes hot after working for sometime. If I leave it locked and idle for sometime, that image fades away and everything becomes normal. But if I start using the phone again for sometime, the problem comes back.
I kind of think this is something wrong with the lcd panel because if I take a screenshot (of the homescreen/recent apps menu when the problem persists) and view it through the PC it looks fine.
I've flashed both lineage OS and xiaomi.eu ROMs and this happens in both of them.
My phone has a LGD panel.
If anyone here has previously encountered this problem or if anybody have any idea about why this is happening and/or whether there are any solutions for this, I would really appreciate your help
I think its called a screen burn issue. Dont have a solution though

right ... I suspected something like this coz it happens only when the phone is hot. I didn't knew the correct term for that ....
thanks for the reply buddy. appreciate it
It's image retention. Which happen quite frequently on ips display made by LG. Many LG's flagship also suffer this symptom. The only way you can reduce it is by reducing the amount of RGB(Red green blue) colour profile by 5-7% though only doable in LOS.

Look under display calibration and change your RGB values accordingly: R: 93% G:93% B93% . It works like a charm :highfive: I use LineageOS although not all ROMs have this feature.

thank you both for the help :good:
I flashed the LOS latest build and adjusted the RGB according to what you've said. Let's hope it does the trick. :victory:

yeah use the LOS 14.1 and adjust the RGB to 90. I suppose it hides the retention effect. To fix the problem completely, I think the only option is the replace the screen.
some people are using KCAL which essentially provides the same options( and more) but keep in mind that it needs root access and kernel modifications.

Hi Guys!
I have a Touch Pro, but i thought I post here, because it's acually the same phone, and here it's more crowded..
I installed S2U2 2 days ago, and just now after waking up the device I saw S2U2 flickering in the background. Like it was a flickering transparant overlay.
So I turn off the device, and turn it back on..
Then when I got the Touch Pro logo (Pre-windows!!) I saw S2U2 stiill overlaying the screen!!!
So my conclusion is: S2U2 Burned in my screen, so if you have it installed i'd suggest removing it before it trashes your display!..
I'm going to return my phone.. hoping they'll repair it..
Cant take photos now.. but will do when i get home...
Edit.. Sorry guys.. changed my conclusion! S2U2 is not guilty.. TouchPro's/Diamond's display is
Sounds scary. Could you post a photo?
Found some information about this.. Thought it would be nice to share, since I will not be the only and the last one with this problem:
TFT monitors don't suffer from burned-in images.. But they do suffer from "retained pixel charge".. this will cause "Ghost images" (like mine)
More info HERE
Is Image-Sticking Reversible?
Unlike permanent burn-in in phosphor-based displays, which is the result of a premature aging of the phosphors of individual pixels, and thus, is irreversible, image sticking in LCD panels can often be reversed to a point of total invisibility.
However, the extent to which image sticking can be reversed depends on the severity of the causes that eventually led to image retention; top in the list is the environmental temperature at which image sticking took place.
A way to remove a retained image on an LCD panel is to run an all-white screen saver for several hours. It would generally help if this image sticking reversal operation were run at an elevated temperature of around 100 deg. Fahrenheit or 40 deg. Celsius. This should help speed up the reversal process.
Some manufactures would recommend instead using an all-back or dark gray pattern screen saver. Whichever method you choose, make sure the LCD TV or monitor energy savings settings will not turn the backlight off after some time of inactivity.
Other manufacturers would recommend turning off the LCD display for a longer period than the time it took for the static image to cause image retention.
While all three methods can help to remove image sticking, yet our best advice is to follow the manufacturer's instructions whenever these are available.

Seems like it will go away when I turn off the screen for a while..
So let's do that, and I'll keep you posted!
damn, try this on your diamond browser:
http://www.jscreenfix.com/basic.php
click the link on the bottom of that page after reading
Thanks! but the applet doesn't work on the mobile browser..
But i've created an avi of it (it works on the pc so Print Screen )
I will play that a couple of times!
Will keep you posted!
oh my god...
i can't understand how it happens.
do you turn off the screen while locked?
[i don't think it's a problem of s2u2...]
I don't think it's S2U2's fault either.. Usualy I turn the screen off. but today while charging through usb, maybe it stayed on, I didn't pay any attention it acually..
I made an wmv file with some flickering screens to stress the tft/lcd screen.. looks like it worked.. stressed it for nearly an hour and it looks gone..
I'll look for somewhere to upload it.. maybe someone else can use it too!
edit: here it is.. :
Click here to open the wmv, right-click save as to save it
g8 work man.
i wait a definitive release of sensorlock, so i'm using s2u2
but i pay attention to switch off the screen ALWAYS

hi i am in the uk.. on three network. i got my htc one on the 3rd of april, and 4 days later the screen started to flicker? not all the time? but browsing? esp facebook or anything page with white? i guess the white shows up the flicker more? like i say NOT all the time but soo annoying!! not what i expected from a high end phone? Now let me just say i love this phone.. but thought i cant have this.. so i fill out support form for htc and they reply quick advising me it should not do this and to get it changed. i contact three go through the whole call centre thing (like pulling teeth) anyways the upshot was.. three sent me another brand new phone the next day (yesterday) and took back my first one. And guess what? as soon as i switch the phone on, same screen flicker? i treated the first phone like a new born baby didnt drop or bash it 4 days=screen flicker. another new phone as soon as i use it = screen flicker!! i so love this phone but im so gutted!! any suggestions from ANYONE would help.
kind regards

This isn't helpful but you must just be unlucky to have had it happen twice because mine's been perfect and I've not seen anyone else on this forum mention that problem with theirs.
I guess you'll have to get a new one sent out again and hope for the best :thumbup:
Could you make a short video clip to illustrate your problem ?

hi.. to be honest i dont think a video would pick the problem up? you know i could just be being a kill joy? ive watched videos etc and there really isnt a problem with that at all.. in fact the quality of the picture is fab? if i could use an analogy? remember when the volume control on your stereo would get dust in it? and you would have to twiddle the knob to cure it? its a bit like that? like i say it does not do it all the time but i notice it with white in the screen? like facebook google and when i am navigating thru the screens on the phone like settings etc? the white flickers white/slightly darker white? hence my example? now ive changed my text messages colour scheme so that doesnt annoy me now with it.. but obviously as a electronics layman.. i cant help but think if it was a problem with the screen itself, other colours would do the same as they would if there was a loose connestion? and also if it was a power flow problem with the battery? same thing? not just the white on screen? so i can only conclude as a layman again.. that it is some sort of issue with the os? screen refresh rate maybe? i just dont know? and i cant help think stupidly or not that when htc finally get around to an os update to 4.2.2 (or whatever it is) from 4.1.2 the whole thing will be resolved?
Could it be the auto brightness doing its thing? Try turning it off maybe that might solve it.
I might be totally wrong, be great if that fixed it though. Good luck
well well well!!!! And there you have it!! or at least something like that? ive always used the multi widgit for wifi bluetooth brightness etc? so i have brightness preset on that. instead ive gone into display settings, adjusted brightness with slider? no more flicker!! NO MORE FLICKER!! who ever you are!! thank you!!!!!!!!!!

Was this happening when the stock power widget brightness was set to medium?
If so, I have the same flickering ( http://forum.xda-developers.com/showthread.php?t=2243483 ), but I've found out that its not the power widgets fault per se, but the the the level that it sets it to. The widget set the brightness to 33%, and that the level which I'm getting flickering at, regardless of if it was set with the power widget or by the slider. The flickering happens on screen with a good amount of white. Google search result webpage is a good test case; it shows the flickering clearly at 33%. It also seems to depend on where the white is on the screen. For example, I can induce flickering at 40% brightness by moving a light colored icon from the bottom of the screen to the top! Moving it back to the bottom causes the flickering to go away. I can also do it by moving around or resizing the Gmail widget. Flickering happens for me to some extent at brightness values between 33 and 45 under certain screen conditions. Above or below these brightness values, the screen is top notch, no endless flickering at all regardless of how much white is on screen. I'm starting to think this has to do with the dynamic contrast feature of the One. It seems as though it falls in an endless loop of trying to change the contrast, as if it cant decide on what to set the contrast to. Or it could be that the dynamic contrast is fighting for a certain brightness value, but the manually set brightness is not allowing it. I might be wrong about this, and it could just be a hardware backlight problem, regardless, I wish HTC had the Sense (ha ha!) to allow us to disable dynamic contrast if we wanted to. I'm pretty sure this is whats causing the issue where people see flickering when the keyboard pops up.
screen issue?
hi..
i had the widget set on the third setting, the fourth being the brightest. i had the same problem with my first phone and thought at the time it may have been a backlight problem? or power flow problem? i sent that phone back and the next phone did the same? after posting on here.. i removed the widget and manually adjusted the brightness. i like the screen quite bright, manual adjustment cleared the problem for me. i gotta say yep the flicker was more visible on screens with alot of white, google, facebook, texts? and way way annoying! i can only suggest you try the same as i did? perhaps it is just a quirk with the htc? or maybe the os? you never know, when the update to keylime or whatever it is called comes out the flicker may go totally?
JUST had this on facebook? hope it helps?

Hey guys,
This thread is not about the camera taking photos with banding lines, instead about the actual display.
Does anyone have vertical banding lines most notorious when displaying a full grey screen in low brightness.
I've read the verge review and seems to have some banding as well, anyone as well? Thinking about replacing it for a third time.

Yes, I rarely get this issue. I captured a screen shot one day just in case, not sure how well it shows up, but look in the middle lower portion of the screen. Almost like a clock hand pointing at 6 o'clock.

You can't take a screenshot to see the problem. Its a hardware issue therefore you can only use an externeal photo of the screen. Check on grey full color screen. I think I will not replace it, I may risk on another issue..

Yeah, I had not planned on replacing mine either. I so infrequently see it, and even when I do, it really does not impact anything. I was not aware it was a hardware issue, seems there could be a bug fix for problem then.

Its funny cause the band shows up in the screen shot on my phone, but probably because the conditions are right, not cause its actually in the pic.
Vertical lines are something you should replace your phone for. Horizontal lines like in the screenshot is just the banding of the colors and happens on every single stock android phone because it's apart of the software

Could u check through a full grey background whether ur greyd are fully consistente? I mean there no faint lines whatsoever. Perhaps ur phone is the same as mine and u have not realized it given that it seems to be fairly normal with amoled displays
I was just about to post about this very issue. I created a quick image to show everyone what the issue is. The lines are not as drastic as I made them look, but it should give you the idea of what it looks like on the screen.

No. That is not the issue we are speaking about. The issue we are referring to is VERTICAL and only appears on greyish/black screens, like the settings screen. The horizontal lines are normal for this phone.

Precisely. You can't really use self screenshots to see this problem I'm talking about. Its about the amoled itself having these vertical banding lines(canvas-like strokes). Open Facebook and tap the search button and tap on the search bar without actually writing any name. Tap down the keyboard. For me the deep blue background has the most prominent banding lines for me. I have one week to think whether I should replace it. If everybody actually have these lines and NOT a solid color on full greys or deep blue I won't replace it.
PS. TheVerge moto x review says that it also have some banding lines on grays. I'd be great if you guys could check ur screens like I just explained. Hope I explain it well
Damn amoled!
Someone with the problem should post a sample pic/screen shot so others can download it and attempt to see the problem.
Just download a color test app that makes ur whole screen of a determined color. Put it on grey and check whether ur whole Grey screen doesn't have any vertical line banding. In case it doesn't have any of these lines, please let me know.
If it does have banding, take a screenshot and see it on ur computer monitor and see how the Grey should be displayed(full solid grey without lines)
I don't care enough to install an app, checking out a screen shot is quick and easy.
Took a photo with my tablet. These are the lines im talking about.
Also use the screenshot so u can check whether u have the same problem.
With the screen shot downloaded and displayed on my Moto X I can detect no banding of any kind. I tried it in dim and bright light. Screen brightness is set to auto so it did adjust with ambient light. Maybe I would see it if I manually cranked brightness to max.

Thank you, so my case is a defect, a third replacement will happen I guess. Great phone nevertheless.
It is possible it is something that was fixed going from 4.2.2 to 4.4.x, seems unlikely though. I notice you are on 4.2.2. I am on 4.4.2.
Impossible, my issue is definetively not software related but hardware related. When I see this screen shot on an LCD based device like my PC monitor, no banding is present. After all the pointless investigation this issue is sometimes present on amoled devices like the galaxy nexus.
So my display after being replaced 2 times in 6 months started flickering. My phone is very hard to be turned on because of the green flickering.
I just want to upgrade to a S6,S7 Edge or non edge. i just want to know if they have the save problem with displays ? I want to have a phone at least 2 years, can you recommand me a phone like that ?
I was just considering switching to a iPhone even though i prefer android on phones ... o how are S6,S7s displays ? Samsung still have the same problems?
Samsung improved a lot on screen quality in S6 and after, so you should be okay

Wow that's amazing. Been using samsung s5 exynos version for the last 1yr. Never had that kind of problem till date. And it have the same display as snapdragon version. And on comparison I found that this is by far the best display out there when compared to other brands.
Maybe perhaps you might be having a faulty unit from the begining.

I have the same problem here with the display and it's not a software problem (same by original os 6 and same by cyanogenmod 14).
After the temperatures are under 10 C. i can't open my s5 with home button i must do it over the power button.
Using S5 for more than 28 months still I have not faced any issue. I just had to buy new charger apart from that not a single problem and yes I mess up with my phone so much but I still working and no display failure yet. And also I have dropped it many times, it still refuses to die.
You are just having a defective model or some internals of the phone are messed up. Because Samsh*t produces one of the best displays..

Its not a good sign. Try disabling your light sensor. Even then if you experience such a problem than it means that your flex cable that attaches the screen with the motherboard needs to be changed.

Hi,
Yes and expect the same problems with the following generations. It's an amoled screen thing. The green colour happen when there's a colour displayed on the screen for a very long time (for example, I have a green on my screen of the size of my keyboard).
I think a solution to this problem is to set the display to turn off after 30s (it saves battery too) and maybe, if you're using a custom keyboard, change the colour from time to time. Use the brightness of the screen to a lowest which would still be comfortable to you (and auto unticked).
This last tip alone is enough to prevent greening. My flickering happened after an incredible fall (it had a tempered glass so the screen was safe). The flickering showed green what it had in memory.
Samsung has a 2-year guarantee for its products so you shouldn't worry for that period of time. Problem not solved, replacement.
Best of luck

Yes and expect the same problems with the following generations. It's an amoled screen thing. The green colour happen when there's a colour displayed on the screen for a very long time (for example, I have a green on my screen of the size of my keyboard).
I think a solution to this problem is to set the display to turn off after 30s (it saves battery too) and maybe, if you're using a custom keyboard, change the colour from time to time. Use the brightness of the screen to a lowest which would still be comfortable to you (and auto unticked).
This last tip alone is enough to prevent greening. My flickering happened after an incredible fall (it had a tempered glass so the screen was safe). The flickering showed green what it had in memory.
Samsung has a 2-year guarantee for its products so you shouldn't worry for that period of time. Problem not solved, replacement.
Best of luck

The funny thing is i already did "by mistake" all the tips you said and still have this. Never dropped the phone though. This problems seems very big though, i expected a burn in to be the biggest problem, but to have flickering at a level that i cant turn on the phone. I wanted recently to switch to a Nexus 6p, but knowing that it uses Amoled too, its a bad ideea. So the only "solution" is to switch to IPS screens? (btw i want a phone that holds on for at least 3 years)
In my research thus far, the AMOLED screen technology is to blame. When the display circuits get old or damaged, they don't sustain current at low power settings. In LED screens, a back light controls brightness, but AMOLED screens send current to each pixel for brightness control. If the circuit is damaged, or any corrosion has built up inside, this could attenuate the current below the point required to sustain light flow. I see this problem with some LED and CFL lights on motion sensor switches. Just enough current goes through the motion sensor to keep it's circuits active, and that current causes a flicker in the light.
With the screen though, since the problem is only resolved when you increase the brightness just a bit above minimum, it seems anything that lowers the display power (auto brightness for example) will cause it to flicker if this setting gets too low. I also noticed that before the screen locks on timer, it dims to low power for a few seconds and flickers as a result. There are apps that attempt to resolve this by putting a translucent black screen over your desktop and apps. This keeps the power up on the pixels but adds a black overlay, kind of like a screen filter. You can adjust the darkness if you need it to save your eyes when reading in the dark but it doesn't help save power any. They also require a rooted device, which could void warranties. The reason for this I believe is because apps are supposed to operate in a way they don't intrude on each other, and a filter that lays over your screen does in fact alter the output of your display rendering. With the added security concerns of these apps possibly collecting screen shots and sending them to another site, I would avoid this. Best to use a physical screen overlay you can put on or remove as needed as long as it doesn't interfere with your touch screen options.
Ultimately, these devices were meant for replacement every 2 to 3 years so if you're like me and you like to make your investment last, best thing to do is apply any work around you can come up with. A repair shop may be able to wipe the circuit boards down with a solution that clears away corrosion, but it won't repair any weakened pixels. I'm still using a Samsung S5 G900F
- And i finally got this fixed. it sounds like the reason for this is that since the latest update your phone cannot decide whether to use hardware or software back light settings. I managed to make the problem go away by doing this:
Go to settings >> system >> About device.
Find "Build number" and click 6 times fast on it.
You will then get the message saying: "You are now a developer"
and then go back to Settings >> system >> Now you will see the "Developer Options"
Now go to Developer options >> Drawing Section or Rendering Section >> Find "Turn off hardware overlays" or "disable hardware overlays" >> This will force the phone to always use GPU for screen adjustments. no more flickering.
but If I turn the brightness ALL the way down, it still flickers like crazy, however, if that's the only time it'll do it, I consider that a win.

Hi, sorry if this was posted before, but with XDA moving to XenForo, search seems messed up, i did several searches and nothing comes up for "flicker" in this whole Pixel 4 XL Forum...
Has anyone else dealt with the low brightness screen flicker? I know it can't be just a bad phone, since i just bought three pixel 4 XL phones and they all exhibit this same behavior.
They are all running LineageOS (Official builds) so I don't know if this just affects the ROM or stock as well (although I've read it might affect stock phones too elsewhere).
It makes the phone pretty difficult to use in very low light situations, the screen will constantly flicker (more noticeable on darker backgrounds).
At first I thought it was just the Opera browser (as that's what I prefer), but it's operating system wide... Apps like "Darker" help.... because you can crank up the phone brightness and use a filter to dim the screen.... but it doesn't get the top & bottom menu/buttons, so those remain like spotlights in your eyes with that workaround.
Just curious if anyone knows whats up with this... it's the only phone I've ever seen this behavior on (and i've used Pixel 1,2,3 XL phones all with Lineage, and a myriad of other devices back in the Cyanogenmod days.... I've never seen a screen flicker issue like this).
Thanks for any help
edit / update-
the pro version of "darker" app works to fix this.... you crank the phones brightness to 100% and with the pro version you can dim the rest of the interface.
hopefully this helps anyone else suffering from this HUGE flaw (again i don't know if its just LineageOS or not, i didn't run stock on these except to unlock bootloader etc)
Hi,
I've seen it once and solved it by switching off smooth display. Not a real solution of course, but I never really noticed the difference between 90Hz and 60Hz anyway.

hmm.... you running stock i guess? i don't see smooth display option in lineage
