Auto Brightness working for you?

Hi Guys,
So I finally got the desire after being with an iPhone for the past 18 months. Lovely phone so far, even if it feels a little 'work in progress' in some depts.
Anyways!
Have any of you with the phone enabled auto brightness? Does it work? When I jump into the settings to enable it it seems to kick in (once i tick the auto brightness checkbox) but once I actually hit OK to save the changes the screen brightness shoots up again and then doesnt seem to react to ambient light.
weird.
I am running the t-mobile android (uk)

Yep, I have the same thing, glad it's not just me then!
I don't think I've seen it adjust by itself at all...

It works for me and I have seen it adjust.

im not sure really if it works because it always seems the same? i have changed it to 30% now which is just acceptable and we ll see if it gives any battery boost

That's the idea, auto brightness adjusts so that the screen looks the same brightness to your eye at any light level. When it's dark the brightness decreases and when it's light the brightness increases thus you see it as thee same due to the way your eye is already adjusted.

yeah Lol exactly, thats the whole point of auto screen adjustment. if you are indoors all (or most of) the time like me than keep it manual to 30-50%. otherwise leave it auto

Mine works a treat the only thing i do is when i go out the house i turn the brightness to manual and put it on full, as this is the only bad side to this phone the led does suffer in direct sun so full brightness is required.

I haven't seen any change in my screen brightness, whether in full sunlight or middle of the night in a dark room!
Is a bit annoying, would like to know if it can be fixed or we're waiting for the next firmware...

Where's the sensor ? With the Hero, placing a finger over the top part of the phone tricked the sensor but it doesn't seem to on the Desire. Interestingly though, there must be something there, the way the screen flashes up when you remove the phone from your ear

Works fine here

It seems that on my Desire the only time the automatic brightness actually tests the light is when I unlock my screen.
I can actually see the brightness change then, but if I switch lights on/off while it's already unlocked it doesn't automaticly adapt to the light.

I only checked it through the Android SDK using Dalvik Debug Monitor and the phone certainly did continuously check and correct screen brightness according to it. Visually, it was too difficult to discern what was happening and when due to my own visual limitations when the amount of light changed.

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.

where is the light sensor of the OGPro located...?

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.

Having this same issue any solution?

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.

Adaptive Display Brightness Problem

Worked Perfectly fine on Oreo but ever since the update when unlocking the screen Display Brightness goes to 0 if i have adaptive brightness on.
anyone else having the issue? so far only solution is to turn that feature off

You will have to keep the feature on and keep on correcting brightness when it's too low, until the system finally understands your preferences
It took me almost 2 full days constantly playing with brightness slider, but now it's all good :good:
Seems that brightness artificial inteligence is a bit lazy....

really? that's a lot of work for someone who unlocks the screen too often. i prefer older auto brightness where you set a base amount and forget it.

I agree with you, I think that the learning is a bit long and I don't understand the need to always go back to zero (it's painful)
But I must admit that once the system is calibrated, it is more efficient than the older one
This is because it is based not only on the ambient light, but also on your personal preferences.
Give it a try, If you unlock your phone very often it should take less time...

Pixel ambient services

I did not have this problem at all after updating to Pie. I never had to manually readjust.
Maybe try to train you light sensor by placing it under bright light (it should then be on the highest brightness) and afterwards in complete darkness (brightness should be lowest now).
After having witnessed very bright light and complete darkness, the sensor should already have it's baselines and should actually switch accordingly.
However if you for any reason still don't like the low brightness in dark rooms you would obviously do that manually.

Question Auto brightness bugged

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.

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).
