Hi guys, I did some searching and couldn't find a fix so here goes:
Often when I put my phone to sleep (tap power-button) the screen turns black, then green again for half a second or so after the "screen off visuals".
I did some searching and it is similar to this "common issues" post:"Screen turns unusual colors / flickers colors when going to sleep or waking." http://code.google.com/p/ice-cream-sandwich-sgs/wiki/CommonIssues
The only thing is, Voodoo control app is now Voodoo sound plus and doesn't have a "Gamma offset" option anymore.
Does anyone know a tool that has Gamma Offset options, or any other fix to this issue for that matter?
It's not a big thing, as my phone is working fine, but I wanted to research it a bit further.
It has happened to me through many different ROMs, mainly ICS roms, but I am currently running ICS333 v.2.0.1 ICS 4.0.4, with the newest Devil Kernel for ICS.
*BUMP* in hope of info/help
- sorry mods if this is unacceptable.
I press lock and the screen flashes red then turns off. Hasn't happend on my previous S3 and G3. Is this a problem or should I not be worried? I can provide video if needed. The phone still works and is all completely fine it's just this.
MIUI Version 8.0.12.0. Chinese Stable ROM. I've had other people tell me this hasn't happened to them so I'm confused :\
I was on a vendor rom and I certainly didn't seem to notice it then but I might have still been happening. Could it be a software issue?

Red screen
Hello. I have Xiaomi mi 5s plus and the same thing is happening to me, when I turn off the screen, it flashes red just before locking.
Have you been able to find the source of the issue, is the phone still working
I've just noticed that my Mi MIX also flashes red before turning off the screen. Having said that, I haven't noticed any abnormalities that affects the phone yet. It seems like it's just a colouring issue before turning off the screen. No biggie.
Can anyone enlighten me on this matter? Thanks
In my opinion it's just a part of weird turning off animation which is brought recently. I realised that recently, yet not that serious observation like you did lol. I guess nothing to worry about.
Mi MIX
7.4.14 Épic
Stopped happening when I used the Resurrection Remix ROM for the Mix, so I guess it's just a MIUI issue, not a hardware issue.
Yup, I can confirmed that it's a MIUI bug. Just flashed the Resurrection Remix Rom, and the red flashing thing has stopped.
Normal in MIUI. Crist, what a detail that you observed, haha
I have Xiaomi Mi Note 3 and the same thing is happening to me. I have been suspicious of tempered glass or hardware. I was wrong.
Miui Version: 9 I 7.12.21
PS: I installed Resurrection Remix ROM but screen still flashed red before locking.
Check developer settings are turned off!
Okay so I wanted feedback regarding this whether someone else is experiencing this or not.
I have gradually observed during the last few days that a lot of my touches to click have gone unresponsive in Nougat. Initially it was something that I hadnt quite noticed but slowly the trend became obvious. Now dont get me wrong, this would happen a few times here and there with lollipop and MM as well, but the rate is far higher now on Nougat. Especially when typing on the keyboard this means mis-spelled words, missed letters, and accuracy is far worse now.
Has anyone else observed this or is it just me?
Just got my xcover 4 with nougat installed i have the same issue.
The sensitivity is low and i need to press a bit higher finger force to respond.
Even with sensitivity (glove mode) set to on things get worse.
I'm seeing the same thing. What is strange is that I'll see the button highlight/depress, but no action occurs. This is on multiple apps.
On what device/OS?
Sprint Note 5 on Nougat
Did you try gloves mode? Does it work?
the same for me on 920cd and the same iusse using S pen
I contacted samsung Greece about the existing problem.
I reported the problems me and you guys have and the tech support told me that your problems exist because you did not factory reset the devices before upgrading to nougat.
Anyone tried to contact samsung about the problem?
They dont know anything about it.
facing same issue screen lagging in note 5 sm-n920s also tried custom rom but still lagging in typing and scrolling on facebook
I have the same problem on my xcover 4 here!!
When I run the the touch screen test, touch screen responds well, but when I want to write a message or to scroll the home screen Its very annoying. It looks like software problem.
please help
Hi guys.
I have 2nd piece of Xcover 4 SM-G390F (first was change by seller for new one) and had the same problem. First 2-3 days all work perfect.. I have installed my applications, work perfect for two days, but after this... --After wake, display react only in centre area, 1 centimeter from display border no reaction or react on xxx touch. After few seconds (20-30) display react on full range, but with lags... So... I go for support to Samsung official at CZE.
Support tells me, that they don't know about this problem, that I'm 1st who has this problem... And some other bull... about unofficial sell and any other. So I post them IMEI and they let me know, if my distribution is official or not, and we'll see what next. They recomend me to go to service center, where somebody looks on my SM. So I see tomorrow.
ROM - official Android 7 Nougat from start using (not updated from other version)
Deleting apps - no effect
Safe mode - no effect
Factory reset - no effect
Apps to calibrate screen - no effect
Okay, now that I got your attention, this is a SERIOUS issue. You may not even realise it, but if you’re not using MIUI, you pretty much have a Screen Burn In / Image Retention problem on your RN 8’s display. It’s temporary though, and goes away after a while. You can see for yourself, but I’ll come to that, and also to why it doesn’t really happen in MIUI. Also, the RN 8 isn’t the only device affected!
The issue:
This never happened over the 5 months I’ve used MIUI. It’s been a month since I flashed Pixel Experience Q, and I’ve noticed when opening Reddit, in its dark grey splash screen, I could see my notification bar and some app’s hamburger menu faintly. It started bothering me, and I started researching. How can I get burn in on a new device!? And heck, it’s an LCD. Turns out I’m not the only one. A quick Google search on “Redmi Note 8 Screen Burn In” gives you tons on people complaining, even here on XDA. Many think it’s a hardware issue, and replaced their display and still faced it!
See for yourself:
Open this dark grey picture linked below in full screen in your gallery. You may notice the notification bar burnt in. For a better example, exit your gallery with that picture open, set brightness to 100% and screen timeout to 2 mins, light mode, and just open settings and leave it alone. After almost 2 mins, quickly go back to your gallery with the picture open. You’ll see settings lightly imprinted into your screen!
Here’s the dark grey picture:

Here’s how it looks (sorry for the crappy quality!):

Solution:
Turns out that the Tianma LCD display panel found in most Xiaomi devices, like the RN 3, 4, 5, 7, 8, Mi 5 etc have to have a specific colour calibration. You need to set the Red, Green & Blue values to 90% in your ROM’s colour calibration. Take a look at these:

Here’s how colour calibration should look, I stole this image from somewhere
https://imgur.com/pgTExqo
MIUI already has the right calibration by default.
But here comes the biggest problem for some of us. Pixel Experience Q, the most popular Custom ROM for RN 8, doesn’t have this option. I tried Franko Kernel Manager with the stock Kernel and Genom kernel, and the display RGB values make no effect. So as of now, I’m stuck with this. Any tips? ROM’s like Havoc should have it though. So dev’s, please set this as the default colour calibration value!
I hope this helped, I put 2 hours of effort into it haha.
On another note, I hope y’all are staying safe from this epidemic!
bro i have it in miui .. its hardware not soft .. i noticed it in different xiaomi devices like note 8 - note 7 - and sure poco f1 .. then noticed it in realme 5 pro .. not found in my very old samsung grand prime / though companies nowadays go to those low end panels .. all of them
I have the same issue on MIUI (stock rom) too.
I did the exact same steps you described and I got the burn in. Well it is not much, I could see it only on full brightness though. Not much of an issue for me on such a budget phone tbh.
Changing the color calibration for all colors to 90% might help to reduce this burn-in, speaking of custom roms to include this as a default setting.
But it won't help with this cheap panel, which is ineed a hardware issue anyway.
Setting all 3 colours to 90 % just reduces overall brightness nothing else.
Thank you! Display colors can be changed on crDroid 6.4
https://t.me/InceptionNote8/66967
this works well for me, use franco kernel manager
It is not the rom issue
I'm seeing this issue in stock rom and i never changed roms till now. It is bcoz of poor quality display panel. Get it replaced ASAP before warranty runs out
I dont know if this is universal but setting the colour tone to cool fixes the issue completely in my redmi note 8
just change the color calibration to this and voila, u never experience burn in screen anymore. i changed it couple weeks ago and no burn in AT ALLL untill this day!

I own a MI A1 it's 2 years, 9 months, 2 weeks, 3 days Old and has screen burns in.
not unlocked bootloader.
no twrp,custom roms,rooting.
but being a budget device (having eMMc type of storage) i have no regrets it performs very well against phones of Exynos 9609(UFS2.0), SDM665 (UFS2.1).
Comming to the topic "screen burns" will go away on its own not a matter of Great concern, leave it like that only it will automaticly go away its not Permanent .......... :fingers-crossed:
Hi all,
I hope that I'm posting in the right place. I am running Lineage OS 17.1 on a Pixel 4XL and I am experiencing a flickering wherein the background color changes from the darker version to a lighter version and back again. This is especially noticeable with the dark theme and apparently it is a known issue (
https://www.reddit.com/r/Android/comments/hnkmln/_/fxc1l7p
, https://www.androidpolice.com/2020/...option-to-show-refresh-rate-looks-like-fraps/, https://www.androidpolice.com/2020/...option-to-show-refresh-rate-looks-like-fraps/). My problem is that I cannot find any of the 90Hz or "Smooth Refresh" options anymore. But, I know that they were there before I installed LineasOS 17.1. Any help is greatly appreciated.

Do you have developer options enabled? If not, click settings/About Phone, click the very bottom 'build number' 5 times. This will enable dev options.
Also you should post questions in the Q/A but not the dev forums. You will get better help in the Q/A.
Another useful resource is the forum for the specific ROM if you do not get results in Q/A. Where you posted the question is more for development of ROMs, kernels, and such so it's not the best place for the type of question. The mods may move it but they may not.

Hi,
thanks for the help.
I do have Developer Mode enabled. I could not find any refresh rate or smooth display settings. But according to this (www.pcmag.com/news/pixel-4-turns-off-90hz-refre...) it seems like the refresh rate may have something to do with brightness and it seems to be backwards in that turning brightness up above 75 enables 90Hz while turning brightness down below 75 disables 90Hz and sets it to 60. I see the flicker with a brightness below 50. Turning brightness up to 100 seems to make the flicker go away but it is really really bright.

I'm not directly on LOS at this moment (I'm using PD11), but I have used it a few times and didn't have this issue (or I don't remember having the issue while using it).
A few questions, first did you find and test the refresh rate in dev options, if so, did it help? Second (more of a personal question than anything else) but you noted LOS 17.1, that's Android 10. Why use the older 10 and but not LOS 11 (18.1) now that it's official? I believe LOS 10 is phased out for Android 11 (18.1) so I'd use the latest official LOS (18.1 Android 11). Third, have you enabled force 90 Hz in dev options and tested that outcome? I know some users mentioned they needed to do this to fix random display issues but I am not directly familiar with them (so it's not tested by me personally).
I ran Lineage based on Android 11, never tried the Android 10 version of it, but with Sultan kernel, I didn't have the issue. Currently running PD on Android 11 with Sultan, no issues here as well.
What's the reason you're staying on Android 10? Also, in the display settings, any chance it's called something else instead of smooth display?
Also, it could just be the rom itself. It seems another user had the same issue. https://forum.xda-developers.com/t/low-brightness-flicker-lineageos-stock-too.4197665/
just figured i'd put this here... i posted this back on December 3rd 2020:
Low Brightness Flicker (LineageOS & Stock too?)
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...
forum.xda-developers.com
Darker app was the only fix i've found that actually worked, i have three pixel 4 XLs now, newest one is running Android 11 / LineageOS 18.1 ... it affects all of them, it's hardware related as you stated above with the refresh rate... that would be a good fix, if you could lock the refresh rate, but i was never able to accomplish that
i have need of miracast in my car now, and Pixel phones still blocking that sucks... might have to find a new model of phone
