just curious if these screens are actually calibrated my first i had a transparant line running down the centre of screen, my second appears fine however when i set it to the same brightness as my first nexus i was getting heavy banding on dialer / greys with task bar pulled down.
So i lowered brightness to 35% and all seems well , however 35% brightness on this is around the same as 65% on my first device. Not so much a issue but did think it was strange as this would affect auto brightness settings between devices.
I've had a problem with the t989D since I got it. Here's what I want:
**Auto brightness turned OFF and the brightness remain at minimum setting.**
However, with all the roms I've tried (Stock, Juggernaut 4.1- 5.0, Tuesday) I always have the auto brightness OFF and the screen always brightens up to about 75% whenever I turn the screen back on.
Note: the settings still show as if the brightness is set to 0%, but the actual brightness coming from the screen is the same as if I turn the bar up to 75%. When I start to move the adjustment bar a slight amount for the brightness, the actual screen light drops right away. It only stays on 0% as long as I'm using it, but then is really bright again when I lock, then unlock the screen.
Is anyone else noticing this? Beyond that, is it possible to prevent the screen from adjusting it's brightness while the auto brightness nis off?
Thanks for any assistance!!
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

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.
I've noticed on my Nexus 7 that the screen will alter the brightness pretty frequently even when I'm sitting in the same place and the ambient light level around me hasn't changed. It will dim a little bit and then brighten a little bit several times while I'm just sitting there reading. It's most noticeable on a white background but it can be seen at other times too.
I'm pretty sure I'm not blocking the ambient light sensor with my hand unless there is a sensor on the bottom of the device. I've also confirmed that there isn't anything wrong with the screen by turning off auto-brightness and the screen no longer brightens or dims after that.
Anyone else think auto-brightness is too sensitive?
It could be anything. I'm sitting in a room right now where a window is about 3 feet behind me and about a foot to my left. If I rotate my device just a tiny bit it towards the window, it becomes enough to brighten my device. Then if I rotate it back to its normal position, the brightness goes back down. It's pretty sensitive.
Are you in a room with windows? Perhaps the sun is going behind a cloud or something and coming back out.
Yes there is a window but this was at night and I had a lamp on beside me. I was being very careful not to turn the N7. At this point I've just turned off auto brightness because its distracting.
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).
