So I've been using 4.2 since the preview builds of cm 10.1 and I only have one issue with all the roms I've tried (cm, aokp, son of android). It's that whenever I turn my phone on there's always this brightness flicker most of the time. I keep my brightness at lowest and then when I turn on my screen the brightness level flickers to max then lowest. It's honestly my only gripe with 4.2. Does anyone know of a fix or possible a rom that doesn't do this? Thanks!
Screen brightness is high suddenly when turned ON

I have also experienced the screen brightness getting high briefly after turning ON the phone. I am currently using KitKat CarbonRom and the brightness flicker time varies...sometimes it's a short brightness and goes back to the lowest brightness that I have set. Otherwise, it take maybe a quarter of second.

Been playing with my new phone and love it but man is the auto brightness a piece of crap. It sets the backlight so low you get weird banding on solid colors and off whites. Just turn brightness to 30% or so and boom its a whole different screen, colors pop and I don't notice any banding. Whites are great too.
They need to fix this fast since it comes with auto brightness on and its going to give people a bad impression.

That's the first thing I did.
auto-brightness is always a little too aggressive for my liking..
It was a problem with the Nexus S as well. Drove me nuts.
Seems AOSP roms are very aggressive with dimming.

known issue. Manufacturers tend to be really aggressive with this so you can get better battery life (yea I know.. pointless right?)
Just wait for custom ROMs. Or go download paulobrien's tweak for the automatic brightness settings. (of course, as others have said, you can just turn it off)
auto brightness has always sucked on Android, iOS has a customizable auto brightness that adjust to the level you put it on initially, where as on Android there's no option to adjust the default brightness when auto brightness is enabled.

Not just iOS, even my 3 year old Nokia allows you to adjust the level of auto brightness. Wish this is native to Android. I found my Nexus One too dim on auto brightness too.
Edit (deleted): redundant post about paulobriens fix
The auto-brightness doesn't just seem too low to me but also buggy. Most of the time it's really dim, but occasionally it will suddenly shoot up to a decent level
Has anyone tried this app? https://market.android.com/details?id=com.nnevod.loggraph&feature=search_result
I find it too bright.. the display is perfectly usable on minimum brightness in a normally lit room bit it keeps winding the brightness up, draining the battery. It seems stuck on about 50%.
My Nexus S did the same thing.. Drove me nuts. I had to switch it off and force it to minimum half the time.
Hopefully the ability to tweak the levels in detail will be ported over from CM7 later. For now, you can use PaulOBrien's kernel where he adjusted it.

Same here, with my Nexus S, too bright.
This is one of the first things I do when flashing a rom on my incredible. They usually have to ramp down the brightness very quickly, probably for battery life. Cm has the tool hopefully it will be loaded soon.

It would be nice if google added an option to set the max and min brightness used during auto. You could just raise floor a little.

Problem I've realized is on SAMOLED devices the screen is an absolute battery killer so there's no wonder they are aggressively keeping it dim. I bet if you ran this phone at 100% brightness just sitting idle it'd last like 10 mins
Hey guys how are u all
Ihave a question can i rise the brightness up with auto brightness working
Becouse if i but mark on auto brightness icant rise up the brightness
Like ios do coz on low brightness there is avertical bending isue on my screen
And iwant to ask if there is any rom that solve the vertical bending problem thank you very much
Get an LCD screen device.
Banding == solved.

Thats your only solution to banding.
Yes there is a solution just rise up the brightness and the vertical bending will dissapear but if you did you cant apply the auto brightness mode and thats the problem
Bigxie's rom let's you set the autobrightness level: it's the only one I've tried so I can't comment on whether there's other roms that do the same thing.
You can use an auto brightness app and set custom brightness levels, like mine.
Ive tried that app, free version on ics 4.0.3 and had several reboots\crashes.
One is when using pattern to unlock:
- Screen is set to turn off after 30 sec, when the screen dims before shutting off and i swipe the pattern it crashes reboots.
Also in normal operation when the screen dims at shutoff point and i do something to wake it it can crash\reboot.
I have had mainly two brightness settings, 40.0 and 130 lux (0.5mA)
40.0 was set at 21% and 130 at 33%.
When commuting on bus\train the light conditions change frequently and also that can cause the reboot\crash.
Has anyone noticed that their auto brightness is kind of broken after upgrading to JB? For example, if I'm in a really bright area and go into dark, the screen does not dim itself, however this can be fixed by going into settings and un-checking and checking the auto brightness box.
Obviously this is pretty annoying... Is there a fix for this?

I've noticed the same. It stays bright a lot of the time in dark places. I haven't noticed it staying dim in sunlight though.
To me, the way it was before seemed broken. It would constantly change its brightness level. This was effected by the light reflected off clothing, etc
I love it now

He he good one
But I Dont find any issue with it either. In fact, if you dig in, you'll find the process consumes 30% lesser battery than before ie. Screen + sensor timing and refresh for both...

I'm actually pretty sure this is the default behaviour for ICS as well its only 3rd party roms that added in the ability to auto dim as well as auto bright the stock way is it only goes dimmer if the screen turns off and back on other wise it stays at the maximum brightness
Sometimes if I'm using the widget to move from full to auto brightness and tap very fast, it'll sit at full brightness. If I toggle slower its fine. Definitely some bug there.
I think auto brightness is much better in 4.1.1. Before it was far too dim, now it seems just right in all conditions.
I'm using the app "Lux Auto Brightness" and it couldn't be doing a better job.
Definitely check it out if you're unhappy like I was with the stock auto-brightness
Sent from my Galaxy Nexus using xda premium
that has been the default behaviour from ages for stock goole rom:
the autobrightness only can increase...it doesn't decrease, unless u lock and ulock the phone or check and uncheck autobrightness
that the intended behaviour google want..the brightness get increased, but not decrease..
So you're saying that the auto feature in 4.0.4 was broken then?

Yes, it delayed the lock screen and when I set my phone down under a bright lamp and it woke up hours later in pure darkness, it might soft reset.
happens to me as well on stock 4.1.1. if I'm in a dark room and put the phone under a lamp or something, the brightness goes up instantly, but it never comes down until I lock/unlock the screen again.
in fact most of the time I think the thing is too bright (but that may be because I come from a nexus one always on the lowest setting since the autobrightness there didnt really work well).
it's a minor annoyance definitely
Same Problem with Note2!
Hi guys,
found this thread during my search for this brightness issue. My Galaxy Note 2 has the same strange behavior. But I figured out something: when I lay down the device to a table or bring it to 0 degrees in my hand, automatic brightness it's decreasing perfectly! Can you confirm this behaviour at your nexus? I guess it's a kind of strange Samsung " feature", maybe?
Thanks, Michael
Ahoy, I was also researching my auto brightness issues when I found this thread. I can confirm the behavior from the previous post on my SGS2 on Jelly Bean 4.1.2.
If the phone is in vertical position and I do the lamp test, it will stay on maximum brightness no matter what, but in horizontal position dimming works perfectly.
Regards,
zytrel.
A couple weeks ago, I noticed that my screen would flicker when it was below about 50% brightness and that it would stop flickering when above 50%. I now have a problem where the screen is flickering and I cannot adjust the brightness which seems to be stuck at 0%. I can just barely see the brightness slider and when i raise it, the brightness remains the same. I don't use adaptive brightness btw and I am also on Android 9 still. Has this happened to anyone else/ does anyone have any solutions?

Never updated to android 10 myself and not experienced that issue. I just leave my brightness settings on auto. Hope your issue is some weird software bug rather than hardware related.
Is anyone having issues with auto brightness, jumping up and down every few seconds? Im currently sat in a dimly lit room with the TV on and my screen keeps changing brightness levels every few seconds, if I pull down the notification area I can see the slider jumping about. I'm guessing the phone is reacting to the TV changing brightness levels as the picture changes but it seems way too sensitive.
Yeah known issue afaik. I'm hoping it gets resolved on an update

One of the fixes in the November update was "Improvements for auto-brightness response in certain lighting conditions.".
I think auto brightness has always been an issue with Pixels. Its a feature I always turn off at this point

Yeah it is up and down like a brides nighty when the light it low on mine, it isn't smooth like it was on my Pixel 5. It feels a bit like the sample rate needs a longer delay because just an increase in brightness on my TV can send my Pro brightness shooting up, the adaptive display needs to wait a few seconds before acting.

Yeah my pixel 5 and 4a 5G never had this issue (same room and lighting conditions) its crap we have to pay to be beta testers nowadays, guess we will have to wait for another "fix" in next update.

Should we really have to turn things off, considering the cost of this phone? Throw in a case and charger and your over £900 in for this phone, everything should work out of the box without having to turn off features.
It's horrible. When I sit at night in a dark room watching TV, it seems to react to the TV and jump all over the place. Never had this on a phone before. Why can't Google get auto brightness right? It's ridiculous.
Personally, I've always preferred Pixel's handling of auto-brightness to that of my recent Note 10+. I thought Samsung's auto-brightness didn't adapt very well (besides the dimmest not being as dim as the Pixel when using in the dark).
