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.

been trying out this rom the past few days even though using sense roms is against my religion (i'll confess later and everything will be fine).
anyway, whenever i take it off of automatic brightness... like say, at night, i turn the brightness all the way down... once the screen goes off and i turn it back on, it's bright as hell again.
oddly, the brightness setting will still show that it's all the way down(even though it's bright as hell), so then i have to slide it up & then back down again.
and then it does the same thing all over again!
am i the only one experiencing this issue? is there a fix for it?
have you given up your booty to jesus?

...nope. Ain't given up my booty to Jesus yet.
Never had that problem, but I haven't messed with screen brightness manually on beta8. Last time was Beta7 and it worked just fine. It does seem REAL slow on the brightness level uptake though. Like when you use the camera and it ramps up brightness all the way... it takes it about 30 seconds or so to readjust it.
Ok i wanted to start new thread with this issue
got a question about the screen. Some times I can sense and see that despite of auto brightness off that the screen adjusts its brightness by itself. It is a little change but my sharp eyes can see this... Do you have a similar thing?
I can easly notice this when playing my country game. When I click on the building menu the screen gets brighter. When i cancel the menu the screen makes darker
Also in sprinkle when I use water the screen gets little brighter
I think this is because the Tegra 3 (or ASUS's implementation of it) adjusts contrast to conserve power. The changes in contrast make brightness seem to change.
I think their settings are too aggressive and they should either scale them back or add an option to turn it off, if possible. I'm sure it's nice for battery life but it does (in some very specific instances) seem to impact the experience.
Note: this is not a doom-and-gloom post. The Prime's screen performance is the best I've ever experienced on a mobile device, maybe any device, overall. So this is a bit of a nuisance but nowhere near enough for me to have an inkling of regret about buying the Prime.
This only happens on mine while in power saving mode.

I'm not sure, I'll have to do some more testing. I seem to remember it happening across the board.
I'll note that Battery mode really does make a HUGE difference in the screen's performance. Colors become very washed out, so much so that I'm really surprised by the impact.
Well in my case this thing occurs on every mode with the same strenght... That sucks
so anyone of you can confirm if this is normal? Do you have the same isue on your primes?
It seems the light sensor has high resolution and Asus needs to smooth up a bit the auto-brightness algorithms If your screen goes up and down then simply disable auto-brightness or change lightning conditions

Like i said auto brightness is off. Can anyone install my country and check his out for me? Just enter build menu and chec if the screen gets a little brighter
it has nothing to do with auto-brightness... Its a feature of tegra 3, it can change the brightness of each pixel to give you the best image and use the least amount of power.. unfortunately its just annoying and not implemented well.
And you cannot turn it off.
Ya I noticed this too last night and thought that I had a defective screen. Made a thread about it earlier. http://forum.xda-developers.com/showthread.php?t=1421002

Hello,
theres a bug in automatic brightness: if you turn it on and hold it against the sun the brightness will go to maximum but it won't get back (darker).

I can't help myself, 3 thanks virgins in 2 days!!!! Owned!!!! last time I held something up to the sun it melted. Its kinda hot!!!!........
Ok in all seriousness I have not had this issue....did you try rebooting your prime? I have noticed some hicups from time to time, like touch tones stop working....but if I reboot it will work again. I am sure its just the newness of ICS, these things will get ironed out in time.
I leave it off anyways. Its a known automatic brightness is a battery drainer. You'll get better battery life with it off.

I think this is more of a feature than a bug, although I keep mine at one certain level anyway.
It's to give you a more seamless experience, as soon as the screen goes off and back on it adjusts. It's so when you're reading an article and move from one area to another, you don't get a surprise mid-sentence. I always hated reading things off my phone with auto brightness on, couldn't just focus on the words had to keep tripping up on a constantly changing screen.
With sun i meant that you can hold it against a bright light
Sry for my bad english...
I've actually noticed some differences in the sensitivity of the light sensor on various units. Some do seem to get "stuck," where others maintain an accurate measurement of ambient light. This seems to be correlated to newer units (e.g., C1 units).
The one I'm using right now does switch lighting both more quickly and, it would seem, more accurately. The ones I had previously would get stuck either on high or low brightness (with very little adjustment in between), and I needed to toggle the auto brightness button to get them to adjust to new conditions.
I found auto brightness on the device to be an annoying burden if anything. I just keep it pretty low all the time. Better that way anyways.
Same problem here - The brightness goes up under bright light, and won't readjust until the next screen off/on or reboot.
Does anyone have a Prime that adjusts back down without turning the screen off?
I swear it's intentional and not a bug, although they should offer you the option of controlling its parameters. Just have to wait for the unlocker and some custom ROMage.
But seriously, I think it's to keep a continuity in your current session, so that if you're gaming or working (the two things this tablet's for) you're not plagued by an ever-changing screen that distracts you...

I can see how the concept of continuity can be good. But in my case for example, switching the bedroom light on - followed by a certain increase of brightness on ATP - then switch the bedroom light off to go to bed - the persistent brightness (tested for >15mins) can be a little straining on the eyes. Although readjusting the brightness is as simple as 'clicking' the 'auto' icon on/off again so that the brightness comes down to appropriate level (it only takes 2seconds to do it) - I think this is defeating the purpose of having the auto-brightness setting in the first place.

Oh I whole-heartedly agree. Going from my living room anywhere else in the house causes blindness with auto brightness on. And it acts completely opposite on this device than all others I've touched that use the feature. And like you say, if it's "automatic brightness" then why would it not be totally automated?
I'm just saying there's definite reasoning and programming behind it, it's not just some bug per se.
Therefore, don't expect ASUS to do anything about it, it'll all be up to our wonderful dev's here; they'll say it's properly functioning even though it's bass ackwards from everything else in existence.
Just wondering if I'm alone with this issue... when I have auto brightness turned on, it consistently wants the display to be too dark. I shut off auto-brightness and move the slider back and forth, and it appears that auto-brightness never wants the phone over 25% brightness, ever.
When I set manual brightness the phone is plenty bright enough to see, even in direct sunlight. But auto-brightness never seems to leave the screen bright enough. Is this common or does my unit have a faulty light sensor?

Yes, this is a problem with all versions, including international. There is a MOD out on the international side that addresses this issue by setting the minimums to a much higher brightness. Unfortunately, we have yet to get any devs on our side to begin porting these over. Hopefully soon...

I actually don't experience this at all on my phone. At home, I have it set manually to the dimmest it will go. But at work, I will change it to auto brightness, and when moving from indoors to outdoors I can see the screen just fine (even with sunglasses on).
I just installed Lux
https://play.google.com/store/apps/...t=W251bGwsMSwxLDEsImNvbS52aXRvLmx1eC5mcmVlIl0.
Seems to have fixed all my auto-brightness issues. Shame we have to use a third-party app to get auto-brightness to work flawlessly, but it's better than nothing. Plus the Lux app has additional features that I'm glad to have.
i also installed Lux, and set it to have the screen at 40% brightness at 0 Lux (default was 20% IIRC), and the screen has been at the correct brightness since.
My guess would be that the default settings in Lux are fine for most people. I do like my screen to be bright most of the time, hence the higher custom setting I put into Lux.
DK
i don't know about all of you, but my screen is the biggest drain on my battery. my guess is the low auto settings is an effort to preserve battery life.
like someone said earlier, i never have an issue seeing the screen inside. only in direct sunlight does it make a noticeable difference. fortunately i have an auto-brightness toggle widget thanks to hd widgets
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.

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
