[Q] Screen brightness very high without auto brightness

Does anyone know why when I turn off auto brightness, my screen gets so much brighter? Even if I have brightness set as low as it can go, it still seems alot brighter than it should be. Which must kill the battery.

If you'd like to compare battery life between the two theres apps for it
But as its been said, better for the battery to have the light a little brighter than constantly be changing.

If you're rooted, Rootdim (search the Market, I can't post links yet) allows you to power down the backlight below the lowest option in Display Settings. It's nice for using the phone in the dark or with a bedside lamp and should minimise battery use if you've got auto-brightness turned off as well.
The only worry is the reviewer on the Market who said its lock option kept the backlight on (at a dim setting) after shutting the screen off on his Droid Bionic but I can't say I've noticed that on my Play.

Thanks, that Rootdim is what I needed.
I tried setting it to MAX, who in the hell needs it that high?! I didn't even know it could go that high, make it a white screen and you've got a flashlight!

Auto Brightness broken with 4.1.1?

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

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.

G Pro Auto brightness not Working

Just curious if anyone else is having this issue.
I have the box checked, but I found myself manually adjusting, thinking it just wasn't very sensitive. I turned on auto brightness, moved the slider all the way to dim, went out to the sunlight, and it had no effect. Unchecked, and rechecked the box, restated the phone, did the opposite in a dark room... No effect.

I believe the slider sets the maximum brightness. So when you go out in the sunlight the spot where you placed it is the brightest it will get.

I thought that also... But when I had the slider at full bright, with auto turned on, in a pitch black room, it should have dimmed, correct?

Looks like my phone might be doing the same thing... I'm wondering if I should swap my phone out before it's too late to exchange it for an S4.

Yeah, you're right. Do you have a screen protector on that might be interfering with the ambient light sensor, by any chance?

I don't think it's a bug. The auto brightness on some LG phones doesn't work like the rest of Android phones. On some LG phones, you set the brightness to a certain level and the auto brightness will work around that particular level.
Say you have it at 75% brightness and auto brightness on, the level will go up to maybe about 85% while outdoors and maybe to about 65% in a dim room. Set it at 35% brightness with auto brightness on, the level goes up to 45% in a bright area and 25% in a dark area. That's how my old iPhone 4 used to work.

The way you described the functionality is what I have witnessed mine doing. I had to play around with it for a few days before I figured out what it was doing. No matter which level of brightness I set, auto brightness will adjust up and down from there based on ambient lighting. I do like having this option since it basically lets you further tweak the auto brightness to a comfortable level. On my other phones, a lot of the times the auto brightness was either to bright or too dark compared to what I would have preferred.

I thought there was something wrong with the auto brightness on mine as well. I have it on 70% auto bright set and it never seems to change. I have a screen protector but it has cutouts around the camera and other sensors and ear piece so I knew it wasn't that and I also tested it prior to putting the screen protector on.
Seems odd that LG would go a different route on what auto brightness is compared to the rest of the Android OEM's. sort of defeats the purpose but perhaps that is why we have to keep the setting so high to begin with.

I got mine to work. Its kinda strange. I was playing around and I shot a video as I played the video back I hit the menus button and there is a setting for auto dimming so I check it and my phone dimmed so then I checked to see if my main auto brightness would work so I went into settings and checked auto bright there too and the screen dimmed. Havent been outside yet but before this the setting did nothing see if you guys can get it to work on yours.

Yes, autobrightness on LG works this way since ICS was rolled out for LG Nitro. At 100% even with autobrightness screen will not dim, and at 0% level with or w/o autobrightness screen will not light up.

No, it's right way because brightness sensor works different than human eye and like was said here other phones usually set brightness too dim or too bright using that sensor.

I also think the work Auto Brightness is on the phone E980 strange ... I do not see any change in brightness depending on the ambient light ... Not like all the other android phones

If that is the case, why is there no effect of ambient light on the screen??? The brightness remains the same whatever be the light condition.

I thought my phone had the same issue as everyone else but noticed this weekend when I stepped into a very bright area my screen automatically adjusted the brightness to a higher setting.

Mine has worked from day one and better than my GnoteII I upgraded from... As others have said, it's configured around the amount of brightness you originally set it to.

Adaptive Brightness Issues

With adaptive brightness on my screen frequently (every 20 seconds or so) changes brightness slightly even when the ambient light isn't changing. It's very annoying when reading and most noticeable with light backgrounds.
Is this a common issue or does it sound like I have a defective sensor?

Same here.
So annoying I had to turn adaptive off.
Seems to be when I move, probably changing sensor and it's too sensitive. My head mush change/reflect light on sensor
Anyway it's so distracting that I can't use adaptive brightness, except when pitch dark I can set to 0% adaptive to have lowest light output

Yep, reminds me of a disco strobe light!

No issues here. I actually think the brightness swing is much better than the OG Pixel XL. I can just leave the setting at 50%. On the OG XL I'd have to turn the brightness down in the living room with lighting from 1 lamp and a tv because it'd be burning my retinas.

I installed Lux Dash and disabled "adaptive brightness" and let Lux handle it. You can go into the profile editor for Lux and setup different presets for different levels of light, you can also adjust the min and max allowed brightness and even setup how you want it to adjust brightness (fade, only set on unlock, dynamic, etc)
It has really made this screen amazing and even helps with battery because most the day my screen doesn't go above 15-20%

I've been fine here with the Adaptive Brightness too. Doesn't change too often at all for me.

I installed Lux also and that did the trick. I assume the sensor is fine since Lux uses it with no problem. It's odd that some of us are having problems and others aren't but it doesn't seem to be a sensor issue.

I'm curious but how exactly is it reacting for you? Are you just sitting in bed with the lights on and it's still adjusting up and down the brightness? Cause that's what I'm doing right now and it hasn't fluctuated at all. If I put it on the bedside table it'll brighten up and when I pick it up it dims but that's it.
Sent from my Pixel 2 XL using Tapatalk

Yeah that's too much fluctuations don't you think I mean on my iPhone x or any other iPhone that I have have used so far I never could tell that the adaptive brightness was on but this device does it in an obvious way and way too frequently that im not sure anymore if this is what it's supposed to do I chatted with a Google agent and they forced quit ambient service thing from system apps and I think that still didn't resolve the issue. I will pop up in a vz store tomorrow and check out if their display devices are doing the same

I'm curious to hear what the tell you. Lux has helped me a lot bit I still notice it. To be fair I think I only notice in a dim or dark room with the TV on but this is the first phone I've used where it's noticeable to me. I'm also wondering if this is how it's supposed to work or if there's something wrong with my phone.

What I described was too much? Sounds appropriate to me. If there's extra light on the phone, I want it to get brighter. If that light goes away, I want it to get dimmer. Now if it was happening with no light changing then I would be annoyed. I keep it at 29% with Adaptive Brightness on and it's not too dark in outside light and not too bright in pitch dark.

I'm having the same issue. I'm on my second Pixel 2 XL so I don't think it's a sensor problem. I only notice it in lower lighting but it's really annoying when it happens. Haven't seen this issue on any other phone. Im trying out Lux now and set it to only adjust when waking up. There were similar issues when Lux was set to Dynamic.

Ever since Google thought they knew better than everyone else and got rid of auto brightness for adaptive brightness, it's been trash for me. I CONSTANTLY have to raise it in dark rooms and lower it in bright rooms. AKA, I might as well turn it off because I'm manually adjusting it every time anyway.
All in all, it's terrible.

You know Adaptive Brightness is a mix of manual and auto brightness right? I remember auto brightness actually having the issues you're describing because there was no way to adjust it if it was set. If you have Adaptive Brightness on high enough, it should be bright enough in dark and bright situations. I believe people's issues are that it adjusts too often or the opposite, it's too dark in light rooms and too bright in dark rooms.

Yeah I know it's supposed to be a mix somewhat. It's supposed to match the setting you set to whatever the surrounding brightness is relative to your brightness setting.
That's exactly WHY it's trash in my opinion though. It's a flawed methodology. I don't want it matching my setting relative to anything. I want it low in the dark and bright in bright rooms or the sun to be legible and not more. It tries to do some meet-you-in-the-middle garbage and it just doesn't work well.

I found the threshold for the lowest brightness in pitch dark with Adaptive Brightness on to be 29%. That should be dark enough in dark rooms and outdoors it's readable to me. What percentages have you been trying?

Mines doing the same thing. Did anyone work out whether it was hardware?
I used a sensor app to see what light was reporting, and it was stable. I can only assume it's a bug.
For those who aren't sure - if the screen is on, and not moving, without any changes to ambient or direct light, every 20 or so seconds the screen will dim to a warmer colour, and then 20 seconds later will brighten to a whiter colour.

Yeah I had a feeling that's what people might be experiencing.

To add on to this thread, this is also occuring on my gen 1 Pixel.
Ever since I upgraded to 8.1 the adaptive display will brighten/darken while the phone is sitting still in a constantly lit room.
I also appear to have lost much of the granularity in the brightness selecting bar. The first 25% or so is as dim as it goes, and only after that does it begin to alter the brightness. Previously it would begin around 10% on the bar.
Additionally, the logic behind adaptive brightness seems to have gotten worse. I previously left my brightness setting always in the same place, and no matter where I was it was either dim enough (at night) or bright enough (during the day).
Real unhappy with this update.

auto brightness too low

hey guys,
im having trouble with adaptive brightness since some time and i am pretty sure sth has changed there.
my screen is just to dark for the most time.
some time ago i could just increase the brightness value and the adaptive brightness would work with that (higher) value, like an anchor value.
now, by doing that, i just change the overall brightness and it will jump back after some time.
is this the same for you guys? it gets obviously when being in a dark room and ramping up the brightness (with adaptive brightness enabled) to 100 percent. now when i disable adaptive brightness, exactly nothing changes in terms of brightness, however former times, there would be still an increase in brightness since 100 percent with adaptive brightness does not equal 100 percent on manual brightness (at least in a dark place). now it does.
is this the same for you? was this an update or sth?

also just tried another one, kikasura or how it is callled. same thing.
just that we are on the same page here: you still can increase the anchor value in brightness settings. or will it, too, just increase your overall brightness for a short time and as soon as lights change or you lock the screen it will be back to previous values?

I stop using auto brightness because some times he is crazy.
I prefer manual mod, like this I have the hand on it and i consum lot less battery (It's my feeling)

Adaptive Brightness is still working fine for me. The way I like to "calibrate" it is when in pitch dark, I set it all the way down to 0. From there it'll always go maximum when in sunlight and indoors it's somewhere in between and does fine. If that's not enough, try resetting adaptive brightness:

It is happening the same to me on very low light scenarios, auto brightness will go to the lower value, setting the screen without almost no bright, besides I put it manually higher. Maybe this happened after a update I dont know.
