Default How is auto brightness?

I hear a lot of complaints that makes the screen too dark on androids, my current phone doesn't have the feature. So what do you think of it? Does it work well?

On my Galaxy S, autobrightness works ok. However on the Galaxy Tab, its set to too dark for my tastes. I just downloaded the app called ""Brightness" from Play Store and adjusted the autobrightness to my desired levels.

i have the OG evo.. and has a auto brightness..
but it is a custom ROM, so not sure (dont remember) if it was tweaked.

it is fine..
only issue is if i am inside and head outside during the day.
there is about 3-4 sec delay before it can adjust to the bright light. during this wait, the screen is too dark to see anything.

Autobrightness on my galaxy nexus is actually pretty bad. It keeps it really dark. I don't really notice until I see somebody else turn their phone on. It doesn't go to maximum brightness no matter how bright it is outside. So yes, it does save battery, but it doesn't seem to kick it up a notch when I do need the extra brightness.

it is bloody annoying. it also does not help battery life IMO. turning it down to 20% is where i find real balance--and less migraines. it is not a smooth gradual transition to have auto on Android. it just abruptly changes like during mid-game and really becomes a pest.

mine does the opposite. it tends to go all the way full hilt bright then down, sometimes sticks on all bright or all dim, or varies too often. i wonder if different devices have different sensitivity levels to the sensor or if it can be adjusted (rooted)

while mid game??
guessing your thumb or hand is blocking the light sensor.. making it think it is darker

playing Angry Birds in differing light conditions usually, but my phone tends to adjust constantly, if it's tilted just a *bit* brightness goes full hilt, tilted back or slightly left or right when holding (racing games) it always goes dim/bright. i disable the darned thing. it has not saved any battery, in actuality, it uses more (cpu cycles when adjusting?) and is just plain annoying.

the worst thing about auto-brightness is that it's not gradual to where you won't notice it. on my car my rear-view mirror adjusts for light/glare, and i never really notice it. on an Android device, this would minimize eye strain during the adjustment. there's an annoying issue of eye strain when it goes from comfortably dim to full-bright in one second just because it was tilted towards a lamp

i just disable the bloody thing. i never need it anyway. it has negative impact on battery and just messes my eyes up. i usually keep my device set anywhere at 20% to 35%. got widgets to do that with one-click. don't need auto anything really. i prefer the control at my discretion, not the OS's.

I have had mixed results from autobrightess from various phones, Android or otherwise. I hated it on my HTC Desire Z because it is too bright indoors. Outdoors it is fine. On my SGS3, I love it as it sets the brightness to a setting I am comfortable with. I turn it off on my Transformer tablet as I use it in the house exclusively. I would manually adjust it if I am watching a movie and want it to be brighter.

For non-Android phones, the auto-brightness on my Nokia N97 is fine, although a little bright for really dark areas. It is also fine on my BlackBerry Tour.

Overall, my main complaint about auto-brightness in general is that I cannot calibrate it to the way I like it. If I want it a little darker or brighter in some lighting conditions, I cannot change it. I have to accept how the manufacturer calibrates it or have to switch to manual brightness.

You can calibrate it actually. I just posted an app that does it.

Cool. I recall being told by a developer that Android does not allow this. I guess he was either wrong or perhaps this feature was not available until ICS/JB. I asked this question probably almost 2 years ago.

Thanks. I'll check this out.
