GS III screen brightness and gamma issues - Galaxy S III Q&A, Help & Troubleshooting

I have a friend that bought a GS III recently. When I hold my GS III up next to his, with the same picture set for the background on both phones, both running on auto brightness, I notice that mine almost always looks less vibrant than his, and he agrees. It definitely isn't just my imagination. When both of our phones are set to max brightness, they look the same, the issue seems to go away. Is it common for different phones of the same model to have different ways of managing auto brightness? Is it possible that the screen on my phone simply has build quality issues? Also, is there anyway, short of always just messing with the brightness slider, to have the auto brightness work at a consistently slightly brighter level than it currently does? any apps out there that fix this?
Has anyone else experienced a similar issue?

Does auto-brightness totally suck? is it just me?

In a completely dark room, auto-brightness will sometimes randomly bump up the brightness level of the screen to, say, 25% (way too bright). In a dimly lit room, it generally stays pinned to minimum unless i move it up manually before turning auto-brightness on (way too dark).
Changes take a long time and are inconsistent. Anyone else experience this?
Never been a fan of auto-brightness. It depends on the light sensor in the device, but I turn this off on most android devices as it just ends up soaking up power anyway.

I have noticed that as well. Specifically the in a almost completely dark room its not set at minimum brightness, and when in a dimly lit room it will be at minimum brightness.
Oddly enough when in the completely dark room if I turn off auto brightness then put it back on it will usually go down to minimum brightness. This lasts for awhile then it seems to bump back up.
mine does this also..
I do recall nearly every reviewer of the Prime saying that the auto-brightness was pretty wonky.
But with that being said, auto brightness seems rather unnecessary on pretty much any Android device. Even Froyo had native brightness widgets.

Ditto here, you will find auto turned off on all my devices. Never seems to work for me correctly.
Same here on my 64gb model on .33 version. Also posted here ...

Can heavily be noticed in mobilephonetalk forums while scrolling the page with auto bright turned off. Even on max or min brightness....
It sucks. Plain & Simple
I do wonder why they have such a hard time making Auto Brightness / Sensors that work correctly. Or at least consistantly. I used to play with it, setting the brightness level, then going to auto on several HTC devices, and while it was a LOT better than the Primes setup, it wasn't consistent which always caused me to give up on it. Seems a waste to even put the sensor in there when no one seems to be able to control it properly.
Maybe it IS an Android thing, for I remember no such issue with Windows Mobile devices. Hmm. Hold out any hope of ICS? Perhaps it will address it, but for now, I am still skeptical that ICS is the Holy Grail everyone claims it to be. It would have to address a LOT to be anywhere near that perfect. Who knows. Maybe it IS that good, in which case, My Prime is really gonna shine!
I don't like it on my HTC Sensation either. Too much dimmed when outside and in bright rooms.
Does anyone have a device with ICS that can confirm if auto brightness still acts the same? Every Android device I have had has the same issue. I have just learned to deal with it although I do not like it.

Yep HTC sensation is the same..
I find it very good on my Sensation, suits me well. But in the Prime its well too low.
Sent throught the wormhole from my CoinInserted Sensation OG.
it's ok. not perfect
I also never use auto backlight, but on the TFP it seems ok.
It's not perfect but it almost always reacts pretty fast to changes in light.
When I'm in a dark room it always goes to the lowest setting.
Sometimes it seems to 'forget' to work and then I need to turn the auto setting off and then back on again and that seems to remind it to go back to work.

Anyone noticing screen flicker?

Not only do I have light bleed but I'm also seeing screen flicker. I really want to keep this device but I'm getting sick of this...
The first thing I noticed when I turned on the device was the light bleed. Its pretty bad, and I normally don't mind those types of things. No flicker here though.

I noticed if I turn up the brightness it goes away.
I don't have light bleed, but I do see flicker if the screen brightness is turned down. It's reminiscent of the original Nexus 7, which had the exact same problem.
I have the flickering too...really annoying. I was hoping that this would replace my iPad but it's not looking good. Although lollipop is pretty amazing so far.
Does it only happen you adjust the brightness? If so, i dont think its a big deal as long as it doesnt happen during actual usage.
I noticed the flicker issue when I first was using it. I then turned off auto brightness from the main settings and started using Lux Auto Brightness and the issue has been resolved as far as I can see. I suspect this is an issue with the Lollipop build's brightness manager and not a hardware issue from the backlight. Also as far as bleed goes, there is apparent bleed when viewing the screen at an angle and looking directly at the edge, however I have found that it is a complete non issue in normal use (even in a fully dark room), which stands in stark contrast to my Nexus 10 which has noticeable edge bleed when viewed straight on.
No Flicking here
No flickering here either.
No flickering, but the auto brightness is very weird! It goes from extremely bright to extremely dark without me actually moving, same light conditions?
No flicker here!
Well, I guess we can all admit screen flicker is of the norm of Tegra.
Im seeing flikkering too.....
Only when brightness is low.
Remind me why Google/htc did not decide to use a 64 bit Qualcomm processor instead? :-\
Do you think that this issue can be solved via software update, or is this issue hardware related, and therefore cannot be fixed easily

considering that not everyone has it
So i say no
This issue seems to be related to auto brightness/adaptive brightness: The same brightness level set manually doesn't flicker.
Seems to be a software issue to me, and it seems highly likely every Nexus 9 flickers with auto brightness on (and at low relative brightness setting) in low light environments.

But, my screen flickers when I am on a constant brightness level. But, it doesn't show up as much when the screen is on at full brightness, just when the screen is at half brightness or just below half.

I guess we aren't experiencing the same issue, then: My screen only flickers with adaptive brightness enabled in low light conditions, seems like it is constantly readjusting the screen between two brightness values.
My Nexus 9 doesn't flicker at any constant brightness setting.
Yep, my Nexus 9 flickers as well.
About 15-20% brightness (fixed). It doesn't flicker all the time and it goes away if you change the brightness level or even by itself if you change the app you are using.
This leads me to believe this might be a software issue (N7/2013 had this too when it came out).

Anyone else having auto brightness issues ?

Its just too damn bright !! Mine seems to get stuck at higher levels and doesnt automatically dim, unless the change is quite dramatic (like dark room). I have to manually tick auto brighness off then on to make it work again.
I have tried using lux and it seems to be working perfectly so i am guessing its a software issue from LG side.
Anyone else having similar issues ?
Yea, it's too bright
I completely agree with you. Mine always seems to default to 61% which is too bright in normal light (45% is ideal for me). It would be nice if you could set the baseline "auto" brightness level and let the sensor adjust from there.

Well i have done some research and seems like an app called ''Content adaptive backlight'' is the cause of issue. Seems like LG have managed to produce the same issue that plagued G2. I really hope they fix it in future patches.

same here ... is there another way to fix it ? besides waiting ?

I have compared G5 MM rom to my G3 and there seems to be no Content adaptive brightness app on my G3 and because of that there is no auto brightness issue on my G3.
I have done more research and there are quite a few latest phone (6p, S7 ) affected by this issue where either brightness is either too low or high.
Only solution is to either get a custom rom or get an update from carrier/manufacture.
I noticed this as well.. I am sure it will eventually get corrected via software.
Chiming in to say same issue here. Doesn't really bother me tho.
Same boat its too bright or dark and when battery saver kicks in you cant see the screen at all.
Agreed. Too bright, except in very low lighting - then too dim. Hopefully software update will fix this up.
also agree! Way to dim in dark room, haven't noticed to bright yet but then I am old and need the extra ummpphhh to see!!! lol
It would be nice if LG could add low and high limits to the auto-brightness.. I think that would fix the problem.
Does everyone use auto-brightness? Does it seem to help with battery life?
So the issue occurs since April and hasn't been fixed yet. I just received my G5 and have the same issue. It annoys me a lot and when I see that LG didn't fix it yet, I am wondering whether they ever will do that.
I have noticed it getting stuck, unchecking it and checking it again sorts it out for a while

An idea for a possible solution for the flickering AMOLED displays

Hello everyone.. You might have that problem where your phone's screen (probably a samsung phone) flickers and goes crazy in low brightness settings.. I've done a lot of searching about the problem or a possible solution. The only working solution I've encountered, which is a software one and requires root, is setting the brightness slider on the lowest point that doesn't cause flickering, then, applying a black overlay to lessen the brightness. I'm wondering about the brightness control mechanism... is it based on hardware and software mechanisms?(case1*) or based on hardware only? (Case2*) In case 2: at least we can adjust the minimum current the phone delivers to the display in order to disable brightness settings that cause flickering. In case 1: we would do as suggested in *case1, plus, we would let the software mechanism kick in to lower the brightness when the hardware mechanism is delivering the lowest amount of current that doesn't cause flickering. It's just an idea.. applying it might be as easy as changing some values in the phone os somewhere or flashing a custom kernel!. But finding that change is what i don't seem to have a clue about.. I have a SGS 5 mini duos.. but i think it doesn't matter as the problem presists in other models (S5, J7) I hope I'm posting in the right forum And i hope someone will figure out a better solution and thanks for reading

ONEPLUS 7T PRO - auto brightness issue

hey guys.
i want to purchase the OnePlus 7T Pro, and i've read that there are problems with the auto brightness.
are there realy problems in the 7T pro model?
were they fixed in the last update?
how bad are they?
i must say that auto brightness issues can be a deal breaker for me
The Auto brightness is quite bad. The screen goes really dull and dim in certain light conditions and one has to manually override it. This isn't a deal breaker, but a big irritant for sure.
Have got 2 updates on my 7T Pro and this hasn't been fixed yet. I don't think this is high priority for OnePlus as there are various other software issues to take care of.

Well... yes, it's annoying. But keep in mind it is a new device and it's a new version of Android with massive changes under the hood.
Older versions also had brightness issues and these got fixed over time. It's a nice device, I use it as my daily driver and it's good. Not perfect. But hey... the hardware is ok, so the rest can be fixed in software.
Generally the auto-brightness and adjustment are responsive and work okay. However there are some scenarios in which it doesn't work so well (dimly lit rooms with ambient light coming from lamps or monitors seems to be the worst case). If you are using dark mode (theme) it also makes the screen harder to read in said scenarios. Also if you have enabled the blue light filter (Night Mode) make sure that the brightness slider is moved to the brightest setting (although even completely disabling Night Mode doesn't solve the issue).
OnePlus were probably more conservative with the brightness levels to save power as well. It's not bad enough to be a deal breaker (I use only auto-brightness as well) but it is a bit annoying and hopefully it gets fixed in a future update (or even better yet, we get an option for different brightness profiles). Honestly, you do get used to it over time but you also kinda lose on the display quality when the brightness is low. You really start noticing it after you increase it manually a bit.
I would probably set my brightness +10% or +20% from the stock auto levels.. I haven't been able to find a way to do this with an adb tweak yet. Make sure the email OnePlus to let them know about the issue.
