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.
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.

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
I have a 920 that came preinstalled with Portico ROM version (I bought it about two weeks ago). It's a great phone and improvement over my LM800.
One thing is bothering me, though. In low-light conditions the screen brightness keeps changing from normal and readable to hardly readable. It's like the light sensor is constantly flipping between two states. I read some report on the internet that I am not the only one.
Some suggested that it could be fixed by turning the phone of and turning it on in complete darkness and unlock the screen. That sounded a bit strange, since the screen will emit a lot of light during the boot process, but I tried it anyway... didn't work.
Anyone else experiencing this issue?
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.
Sent from my Nexus 9 using Tapatalk
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).
