[ICS] Fix for screen flicker issue

Hi.. I think I've found a working solution to this annoyance...
1) turn off auto brightness
2) manually adjust it to the lowest value
3) restart the phone
the flicker should be gone!
My setup:
Nexus S (T) 4.0.3 Stock
Static wallpaper
PIN code lock screen
If you can live with the 'dim' screen, you should be happy now just like me. Hope an official fix will land soon.

Doesn't work on mine, tried before, screen still flickers.
Running AOSP+ with Eugene's kernel.

One of the sources for screen flicker is increased screen hz , combined with improper voodoo color configs and also some CPU govs cause it also

Turning. Off auto brightness only resolves the green screen not the flicker when taking phone out of standby
Also no need to reboot.
Its color driver for voodoo with ICS
People here said supercurio working on voodoo color 2
Temp solution up your gamma settings with voodoo color plus or get a kernel that has "colorfix" gamma setting is locked at setting
the gamma setting required to get rid of this problem is too high for my taste
i can live with the millisecond flicker for all around better colors doesn't bother me its not going to damage anything
gamma too high makes colors less vibrant.

sorry guys... false alarm. apparently i jumped to the conclusion too early. the problem is back again since this morning
ps: i was running unrooted stock 4.0.3 but thanks for the technical details guys. it helped me understand what's actually happening under the hood. cheers!

matrix kernel 14.5 with lag free gov has eliminated this problem almost completely for me.

Also doesn't work on mine.

[v7][ROM] KANGYS | ICS | AOKP | Fastest & Most Stable | 15/01/2012 With Matrix 14.5 kernel.
Please try this rom / kernel combo, u will see the difference.

LOL guys that say that "Matrix fixed the issue".. You do realize that he deleted Voodoo completely right?

Doesn't work, running AOSP+ rom with Speedy.

Don't think its a voodoo issue as it happens on stock rom / kernel.

You do know that Supercurio himself has said that people should stop using Voodoo Colors?
EDIT: Steve Garen has also removed Voodoo colors and its freaking awesome.

if voodoo was removed completely from his kernels then we wouldn't be able to adjust any color setting in voodoo app not to mention the the settings wouldn't even be available
and that's not the case with both kernel version
like i said before lowering gamma will cause green flicker
Color fix kernel doesn't allow gamma adjustment thus no more green flicker granted not an actual fix but it is for his kernel and saves him from headaches from users who don't know how to troubleshoot themselves
The other color kernel gamma and RGB can be adjusted but expect green flicker when lowing gamma

actually there are 2 things ... one is the green flicker which is experienced when using Voodoo colors with low Gamma and another is just a quick flash of the screen when locking the phone i've seen it on my all stock ics too it happens sometimes not always just a split second after locking the device

removed my comment
ill take your word if its intermitting can be tricky to reproduce i didn't give enough time
haven't used stock for while that's why i had to test again so maybe it did before just don't remember

Yeah, on SG's kernel I've got no green flash but I do get the slight flicker. It doesn't bother me like the green does though. Its really brief and since I use an all black background and keep the brightness low I hardly can notice it.

Wtf I never deleted voodoo xD

Its the quick flash after locking is what In am in about, matrix fixes this 90% of the time.

[Q] Screen Brightness Issues. Any Solutions / Ideas?

I have noticed my screen changing brightness depending on how bright the picture is on the page. A good example is reddit, when on the home page the screen slowly steps up its brightness so far, after clicking a link to an image or other dark website the screen slowly steps down the brightness. It does this regardless of what the screen brightness is set at as I have tried different values and on auto and it always does it. Anyone else have this problem or have a solution?
Thanks,
Mike.

Possibly not a solution, but I use this free app
https://play.google.com/store/apps/...SwxLDMsInNvZnQua2lub2tvLnNldGJyaWdodG5lc3MiXQ..
I set mine to 20% and just leave it alone, I never use auto.

I have the same problem at Paranoidandroid 2.99.

None of the above worked.
Anyone else have an idea?

Bump, still got the problem

I think the TV light makes a difference to the Nexus 7 brightness, as the TV alternates between bright and dark lighting.
I read my Nexus 7 without glasses, and so I can hold it very close to my face thanks to my short sightedness. This means the Nexus 7 screen light reflects off my face and affects the autobrightness. I suspect that black warpaint smeared on my face might be a solution.
But the real solution should be simple - Google need to average out their sensor readings and transition screen brightness changes smoothly and less frequently.

Unfortunately none of these solutions have worked.
It does not seem to matter whether or not the screen is close to my face and thus sees the reflection, I can do it in a constantly bright room with nothing in front of the device and I still have this weird change in brightness.
Any more ideas?
Thanks,
Mike.

Hi, MikeyUK...
I had the same problem myself for a long time, until I stumbled on this..
http://forum.xda-developers.com/showthread.php?t=1815414
It describes the cause, and offers a solution... unfortunately, it does require you to be rooted though,.. but it worked, (at least, it works for me)... no more screen brightness fluctuations.

Thanks for the response. However, I would like to keep my device unrooted if at all possible. At this rate I might try and return it to the store because it is not right. Another family member has the same device with no problem which makes me a little bit suspicious.
Thanks,

Adaptive [Auto] Brightness Issues

Is anyone else noticing brightness issues with the OnePlus 5? For me it goes way too dark a lot of times in a lit room and goes all the way down in a dark room. It just seems like it's always favoring the lower brightness. I'm getting fed up wth having to manually adjust it.
I had the OnePlus 3T and it didn't behave this way.
Anyone else?

Yeah, OnePlus seems to have some work to do on their brightness curve.

has been fixed with 4.5.5 for me

Has anyone looked into the screen_auto_brightness_adj setting in AutoTools custom settings? You can modify this value.....but I was curious if anyone has tried this to fix it.

Oh I'm sorry.. I meant that there was a thread already in place for this issue.. - and you returned the phone? What did you go back to? Please tell me not Sam suck or icrap

Did you set it on auto?

I am at the moment testing disabling content adaptive backlight. So far I am liking the behaviour of automatic screen brightness.
I downloaded MyAndroidTools from PlayStore. I changed the tab position on these three locations:
1. [Service>System>Content Adaptive Backlight Settings>CABLService]
2. [Broadcast Receiver>System>Content Adaptive Backlight Settings>CABLReceiver]
3. [Activity>System>Content Adaptive Backlight Settings>CABLPreferences]
This tool needs ROOT to work.

Auto brightness stopped working

Hi guys I have a problem on my s8.
Auto brightness always worked for me, but I just noticed that now it stopped working at all. Like, usually if i set brightness to max and then set autobrightness on, it auto reduces it to like 25%, meanwhile now it doesnt change the brightness ever. I have the feeling that auto brightness stopped working after i installed the last patch with odin (the UK unbranded one) since I patched it like 4 days ago and in the past weeks it worked fine. I dont think its a hardware problem because I tried sensor box app and in a black room it shows 0 while in a light one it goes to over 100 and next to a lamp over 2000.
Any idea what could be the problem? And how to fix it? I really would hate to do a hard reset since i'd lose too much stuff... could it be the patch that has a bug? Thanks in advance!

I have similar issue with my phone after latest update. I did hard reset without luck. All we have to do is to wait until new patch will be released and hopefully fix this issue. Regards

I'm really surprised that Samsung will go live with a firmware with bugs like this, I guess they really dont test anything.

I think is the same for me ! With AQG5 firmware (the last one) when you change the brightness with auto brightness on, the phone memorise the setting with the ambiant light condition : you can see it by doing the following : turn auto brightness on and then set brightness up or down. Then uncheck auto brightness of and place the curser at the opposite. At last put auto brightness back on and the brightness will jump where you put it before like the phone memorised it.
Also with auto brightness on you can put your thumb on the sensor in the upper left side of the phone to simulate darkness. The screens goes darker and as soon you remove your thonger he goes lighter.

I dont understand why just some of us have this problem. They should released a fix soon because its really annoying not to have it working, I dont want to have to wait a month or more like this...

It pissed me off so I downgraded to AQF7 : the issue is now gone =)

Same thing over here!
The AQF7 update was by far the best and most stable one to date. Now my home button problem is back and lag also!
Before it I had home button issues with response and lag whille scrolling. Whit the current update everything came back!
Samsung really needs to get their s*** together!

Well... when they released the AQH3 in the changelog it said they fixed the auto brightness thingie, yet I just installed it and guess what? I still have the same problem. Auto brightness still doesnt work, like in the firmware that came out a month ago.
Anyone else tested it? What the **** is Samsung doing?

No one tried yet?

I agree with you, the autobrightness still doesn't work.

Any way to fix this? I am using an app called lux, but it's not perfect, still better than nothing

I have the same problem. I saw another thread that said it's not a bug. They made it that it learns your patterns, so it won't change when you hit the auto brightness button, but it still does become brighter when you go outside, and dimmer when you go inside.
I'm not happy with it though, as it worked perfectly for me before this update, and this is just very annoying.

Two fire tablets showing different brigtness

Hi guys,
I have to fire 7 in tablets both bought at the same time from same place. Both are running the same Lineage-12.1 ROM (12.1-20170802-Unofficial-ford)
But for some reason when i keep them side by side one of them has a very dull screen brightness where as the other is nice and visible. I am not sure if this has to do with the hardware or some missing setting in the one that is dull. I tried making both 100% bright from the upper menu but the screen difference is still the same.
The bottom image is the brighter one. Any idea if some setting somewhere is causing this?

On checking further I noticed that the tablet which is showing dull color seems to show the exact same even when I adjust the brightness slider in the top menu. When the slider is on 0 or 100% its the same. that tells me that the software slider is somehow broken?

Known kernel issue with custom ROMs. Symptoms typically rectified with a reboot. If no joy try a full power down with a 5 sec pause before restarting.

Sorry for the late response Davey126, for some reason it didn't post my reply when I used my cell phone the other day. I tried to restart a few times but still have the same screen issue the brightness controls dont respond. Will upgrading to the latest release help with this issue? Is there any other fix to permanently fix the problem?
Thanks for your help.
thanks,
Matt

Probably not. Likely have to sideload a full version of FireOS to refresh/replace the kernel - then start over. There is no known 'fix' for the problem other than keeping memory load to a minimum (or using the swap tweaks that I outlined elsewhere).
