Hi guys! I need to confirm something if this is just an issue of my phone or this is just it on all MT4GS devices.
When manually adjusting lcd brightness does anybody notice that brightness levels past middle seems the same? I mean when I adjust the brightness level on settings and when it's past the middle level the brightness doesn't seem to increase anymore. It's just very noticeable on the first 3 levels. Hope anybody here could give some feedback.

On mine the increase or decrease past the middle is subtle but it does make a difference. Whether you can notice it depends on your ambient lighting.
Really? I'm pretty sure mine doesn't really adjust it's brightness... And I tried every ROM I can get even stock and still the same. Would love to have feedback on some users also from this. Maybe it's with the LCD type. If I can confirm that this is a software problem then I will really be increasing the brightness level by modding it.

I checked again in different lighting... a dim room, a brightly-lit bathroom, and outdoors in daylight. I could not tell any difference outdoors or in the bathroom, but in normal lighting and more so in the dim room, it was very obvious that there was change past the middle. This is using the Miktouch 0.7 rom with standard kernel.
Ok I'm gonna try it in a dim room later. If it doesn't change only means I got a broken hardware :/ BTW I'm using a full stock ROM when doing this.

Im on pacman rom and my brightness adjusts past halfway
Ok confirmed I got a broken brightness level... lol dunno how this can happen but the level works only up to 1/8 of the full scroller in the brightness setting. Any adjustments past that won't work anymore.
tried it in stock rom, miktouch rom, sense 4.0 rom and CM9 ROM results are the same. So lame I just noticed this when I used my phone from a very bright sunny day and the screen is barely noticeable.

On mine, when moving past the middle there seems to be just two minor alterations, at the 3/4 mark and the full mark. I can notice them when I'm in normal room light and more so in dim light.

It could be that automatic brightness is turned on overriding the manual setting, depending on what rom you are running.
Nope can't be possible... The setting is working but not fully. I can adjust brightness only up to the 1/8 level of the scroller past that brightness does not change anymore.
Do you experience screen flicker for your tablet when;-
1) Brightness set low manually. espicially at night !
2) Auto brightness set but flicker comes again when screen brightness is low in dark room.
3) Wifi is turned on and signal is low.
note : i disable the "auto adjust screen power" and provlem still exist on low brighness !!
My friend has the same problem and he can't figure out the reason :/
In GT2 i don't have this problem but with nexus7 yes.
is that individual problem for this tablet or all of galaxy tab 2 7.0 have this problem ??
please what should do ?
i noticed somethings :
1-screen flicker on low brightness under 20 % when i rise it above 20 % it gone !!!
2-it show clear on background color white !!!
3-that happen sometimes not all time and when i Lighter down screen a little by little the problem gone !!!!!!
waiting your answer ..
thanks

Since you are using the official firmware, then we can rule out the possibility of a bad modification from custom firmwares as the cause.
First thing to try usually is to see if the problem still occurs after a fresh factory reset, so do backup your stuff first.
If the problem still exists after a factory reset, then it could very likely be a hardware problem with the LCD backlight & you should send the tablet in for servicing.
the problem almost solve when i use app ( screendim)
www.4shared.com/android/h9Qv3UW8/ScreenDimFull.html
why is that ?!! what do you think ?
I have noticed this same problem with GT2, but no where near as often as with my Nexus 7. Ive also noticed my polarized sunglasses have less impact on the GT2 than Nexus 7 when the device is held in landscape position. I've just gotten used to the flicker I guess, because I rarely notice it anymore.
AW: screen flicker on low brightness
Same problem on my tab below 30% of brightness. I'm using Custom Auto Brightness to solve the problem.

I didn't change anything else in Advcanced preferences.
I use CM10.1.
i use app ( screendim ) like i said about one week and it is very simple and the problem almost gone when i put on low brightness !
Actually these are considered workarounds rather than solutions.
I use my Tab 2 at below 30% brightness as well on stock (albeit rooted) ROM, it works just fine.
If the root cause is likely to be a hardware problem, then you should send it in while the device is still covered under the warranty to replace the LCD.

actually it happen with me only on lowest brightness and only sometimes not all the times and only sometimes when i turn screen on for 30 seconds and then it gone !! and when it gone it isn't come back until i turn screen off and on again (and not all the time ) !!
really that made me crazy !! but after use app ( screendim full ) the problem don't show almost time on low brightness !!
what do you think ? is that wrong to use apps to soleve problem or should take it to SAMSUNG service ..because it will take week to diagnose problem !!
is there any apps that can make backup to all apps and all settings and all homescreen settings and games saved for restore it if service make data reset for tablet ??

Right, I've tried 4 tabs at my local dealer and everyone had screen flicker on low brightness - more or less. Especially when it's dark it is easy to see. 2 of them showed the screen flicker after a short period of time while the screen was activated. The other 2 tabs showed the screen flicker after about 10-20 minutes. Every tab came out of the box. I think it is caused by a cheap LCD panel.

On my panel screen brightness below 30% is too dark for me. So it doesn't matter for me. So I set the minimum brightness higher via Custom Auto Brightness.

That's what I'm afraid of. If I sent it to Samsung and the screen flicker doesn't show then I get the tablet back.

Make a nandroid backup for example.
Interesting, I was wondering which country/region do you all reside in from which you purchased the Galaxy Tab 2 ? This sounds like a batch problem if so many people complain about similar issue.
From where I hail, & based on the local forums, I have never heard of this issue with Galaxy Tab 2 in general until here on XDA Developer forum.
I may not be an expert but from the description of the problem by various members, it seems to be a serious hardware flaw that ought to be replaced under warranty.
if problem stop at this point that okay and it isn't bother me anymore when i use app ( screendim ) ...but i am fraid to developed to more than that !!!
if there is expert tell me will be more than that with screen or not ?
Hi,
i got my Zenfone 6 today, and i really like it, but there is one thing that probably makes me return it...
The display is flickering when it‘s set to really low brightness, i think its the backlight.
I‘m not sure if it's broken or not. So, am i the only one with a flickering display?
Thank you

I had the same situation yesterday, it was on low brightness too.
But only for a few seconds, for now, everything seems fine, even in low brightness.
With adaptive brightness set on or off?
Do you have the latest firmware version WW-16.1210.1904.133?
It doesn‘t matterif adaptive brightness is on or off, it does it as soon as the display lowers its brightness to the 1st 1/4 of the brightness bar...
Ok. Do you have the latest firmware version WW-16.1210.1904.133?

Hi, i have the same problem. Received the phone a week ago and trying to find a solution. I am on the last firmware, tried the dev option about overlay, hard reset and still the same. Going to send it back to Asus for a refund...
I wonder if this is software or hardware related. As of now i can't use it at night with low brightness.
It will probably be a problem for a particular phone, I would recommend that you replace it with a new one.
https://swedroid.se/forum/threads/snabba-fragor-snabba-svar-zenfone-6.165775/page-38#post-2443073
Thanks for the feedback. Called Asus this morning to replace it hopefully.
My Zenfone 6 does the same. If I set the adaptive brightness on the low brightness flickering disappears. I think it's a software related problem because others Zenfone have the same behaviour.
Tried it. No matter the settings it flickers. I found a video that match the problem, weird no one noticed : youtu.be/DN1La8AbZsI
Check at 1.16 min, on the right side, it flickers like that, when the luminosity is low. This is what i see on my screen.
Same here. White backgrounds flicker when brightness set to low. Tried disabling HW overlay, but it didn't help. Phone on the latest firmware WW_16.1210.1904.133.
Anybody letting the techs at Asus know about these problems? I would like to hear about a fix before I buy anything.
I am in touch with Asus France, i have to send back the phone for an exchange as they told me it MAY be a hardware problem.
I linked the thread to them if it can help.
Every zenfone I have had (2 and 3) have had this issue.

I think it's a software issue...if you let the brightness working in auto mode the problem disappears.
It is set in auto mode on my device and still the same. With or without doesn't help sadly.
Hmmm is this international version? The U.S is coming next month. Hopefully this get fix before I'm buying it.

Mine is flickering when brightness is set to low (about 1/4-th of the brightness slider and down) no matter auto or no auto.
Funny how we here in the US complain that so many phones are released in the EU, or India, or China long before they ever appear here....but in reality it could be that we benefit from this practice so that some of these issues can be resolved by others before we have to deal with them.

I hope that when this phone is released in your country, this issue will be solved definitively via software update. The way I see it, this problem isn't a huge problem, fortunately. Actually the screen flickering occours only if the brightness is set to a very low level (e.g. <20%) but, with this setting, the backlight is too dim as well for use even in a dark room (obviously for my taste). Since I use adaptive brightness with default settings, the minimum value the screen brightness reaches is 34% so I never get the problem....
I'm facing this issue on my one plus 7 pro nebula.
Please help.

I'm not seeing this at all. What are your display settings and have you changed them at all? Refresh rate? Quad? Is it only trailing darks?
Thanks
Can you compare it to another amoled smartphone?
This is normal. It happens to any AMOLED device with low brightness

Was the same with my pixel 2 xl with brightness turned down low. I'm assuming this is normal? (i know it shouldn't be)
Ahh ok got ya. Well glad you found some consistency.
It IS normal on OLED...

So you're saying your auto brightness is off and you have it manually cranked all the way up but the issue is that it randomly dims and then gets bright again, on and off constantly?

It's difficult for me to determine whether it's something intentionally done by the software to limit the screen brightness or a defect. If it's the latter and you can still exchange or at least attempt a warranty swap through a carrier, it maybe something to look worthwhile to look at.
Sent from my SM-N986U using Tapatalk
If you're saying that the Note 20 Ultra isn't as bright as previous Samsung phones I would concur!
I have an S10+ and Note 20 Ultra, and I don't know what brightness "problem" is people talking about. They're almost identical. You know that you can adjust brightness to your taste, even in auto, right? By default is dimmer because of energy saving stuff, but you can move the slider up...
I have a note 10+ I still daily, definitely dimmer than my n20u, but that sounds like software trying to adjust for some reason.
Samsung is buggy, will always be buggy I feel like.

if you use iphone about 5 min its become hote thenn the screen dim
i know its in note 20 ultra as well if you use the phone surf lets say facebook 5 min its become little hot and dim the screen (not much ,little bit) at least with the exinos chip

no man auto brightness is off
try it out! if you in a dark place not alot of light even if the screen on full brightness it still will dim itself abit
but when you go no outside but to room with much more lite the screen will be more strong
its like the auto brightness even when off still doing somthing to keep the screen
It may be to protect your eyes or something but mine does this as well.
Auto Brightness - Off
Manually set brightness to highest point
Then if you go from a dim room to sunlight the screen will brighten up even with auto brightness off so you can see it under sunlight.
Anyone manage to get this issue resolved? When the phone get hot, the screen dim to the extend u cannot see clearly under the bright hot sun. Using Samsung superb chip. Really lots of issue with note 20 ultra. Samsung taking customer for granted now!

Works well on all my phones, but our individual experience with chrome doesn't add much to the fact that Samsung's software might be limiting the user experience, which it is, more so than other manufacturers.
After all, we should be the ones to dictate what we want to use for web browser or any other app and not have to change it because samsung has buggy software managing it's hardware. Other manufacturers have it down, imy currently loving my xperia mark 2 and the way it's optimized.
