Nexus 5 auto brightness problems? - Nexus 5 Q&A, Help & Troubleshooting

Hey guys,
I'm using my new nexus 5 for about two days now and something seems to be wrong with auto brightness (at least) on my device. The phone makes the screen brighter just fine, but dimming it when it gets in a dark environment doesn't seem to work really well. Can someone give this a try please?
Just turn off the lights in a room and see if the screen adjusts correctly. On mine it doesn't.
Turning on and off auto brightness fixes the issue but as soon as the screen gets brighter again, the problem starts...
Thanks in advance

Good spot, I seem to experience this as well ! Exactly as you say works fine until the brightness gets set higher then it wont ever fall back its as if it can never lower only increase brightness.... odd!

Did you give it a minute to adjust?
Since my Nexus 5 isn't here yet this is what I've observed on stock Android in the Galaxy Nexus and other phones:
While it should go down after some time it's pretty common for auto brightness not to dim down as soon as it gets darker. You don't want your brightness to jump up and down just because the lighting changes for a second. And since turning the brightness up is much more relevant than down it goes up almost instantly but before dimming back down it monitors the environment for a while.
When you turn auto brightness off and on again you force the sensor into a new reading so this should set the brightness to the correct level without delay.
But it wouldn't be the first time auto brightness was bugged on a phone.

The delay really annoyed me on my tablet running vanilla 4.2 so installed lux which works well. You set the brightness how you want it at a given light level and then it sets the brightness according to the ambient light each time you wake it up and holds that setting until the next time you wake it up... best of both worlds.

You're right gokpog,it does work I just didn't give it time. It took around 10 seconds to change the backlight levels which is much longer than the nexus 4 which is why I didn't notice it. Hopefully there is a more sensitive curve in the future

Yep this has been the case with stock android for a while. Feature or flaw you decide but it is what it is and is across the board no matter what device if its using stock android on it

Well it doesn't seem to work as expected to me: go to a bright place, then to a very dark one. Yes it will dim a bit but not quite enough. Remain in the dark room and turn off auto brightness. Then turn it on again. The screen will get significantly darker than it was before

I have find too that the automatic brightness take time to decrease brightness, also increase, but the most annoying is that with the same level of light and without moving the phone, the brightness goes up and down erratically, without a reason, it didn't happen with any of my previous phones

I just installed this app today, I've had similar problems that weren't present on my N4. With this app running, when I turn the phone screen toward a light, it brightens, and back to face a darker place it dims almost immediately. To give me more battery life I've tuned the brightness curve to be a bit low, N5's auto seemed to be too bright for me overall anyway. Be sure to tinker with both the settings and advanced settings areas, by default the changes are sharp but you can make them fade instead. Fixed the problems I had at least.

I have the same problem with my Nexus 5.
Additionally, since day one, I've noticed that the phone consistently auto adjusts the screen to be slightly brighter than necessary given the ambient light.

I just noticed this issue last night, or at least it's similar. I was reading in bed for a few hours and occasionally (maybe every 15 minutes) the screen would suddenly dim to about half brightness and then brighten back to where it was originally. It was driving me nutz. I've also had a few random reboots, though not while I was using it. I'd notice it on my table booting up. FYI, this is stock with the latest update, no root or unlocking, and still has plenty of free space in memory. I've only had it for about 4 days.

[Q] Adjusting brightness

Hi all,
Is there any way to reduce screen brightness even lower than what we could do with built-in settings? Thanks.

I'd love to know too. The screen is just a touch too bright in bed at night

I'd like to know this too, I have it at the lowest setting usually and it's still a little bright, I don't even need to turn it up outdoors.
On my modded galaxy s, the darky rom come with an app called "screen filter", it enable you to get your screen WAY dimmer, may be worth a look for in honeycomb, nice for froyo/gingerbread, you even have it in the task menu... my 0.02cents
I noticed that i always have to set it to the max cause it cut down on the glaze. This screen is like a mirror during the day.

try that app (requires root)
AdjBrightness doesn't work. I'm running Modaco ROM HR3, which means it's rooted, but AdjBrightness keeps saying it requires root. Thanks anyway.

Try "Brightness level" by curvefish. I can't guarantee it will work but it works on my g tablet?
Sent from my DROIDX using Tapatalk
I don't think any apps can make it dimmer, without rooting and system access. Brightness level widget doesnt make it any dimmer (it reports the brightness level as 8%, when the system brightness bar is all the way to the left, and when set to 0% in BLW the screen doesnt change).
One of the first things that I look for before buying any device is can the screen be set to a low enough brightness. Manufactures often overlook this in their quest to make screens as bright as possible, and in one case I ended up taping a piece of plastic over the screen of an Acer netbook as a filter to get the brightness down low enough to use in a dim room. In the case of the Transformer, I could not try before I bought, but the screen does go down pretty dim.
+1 for Screen Filter. I don't have a TF yet so I haven't tried it but it works great on my SGS and doesn't require root. I suspect it may not work as well on an LCD as on my SAMOLED screen on my phone since it doesn't actually reduce the backlight, but it's still worth a try.
Thanks, screen filter works!

[app] ScreenOff

Hi guys, if you think how the power button will break sometime because it feels so fragile, maybe you want to use this app. I made this app for personal use, but I do want to share with you.
This app basically only make the screen brightness to 0 (zero), and you gotta wait for 10 seconds to let Android call the lock screen.
nb:
if you didn't wait till time out (10 secs), you are still basically locking it manually. that means you have to press the hardware button twice to wake the screen up
Is it possible to change this in a way you can control how bright the screen is? The lowest setting is '12' that i can get and even that is nearly too bright indoors for me
I havent seen an all that does that

You should try an app called LUX. It will allow you to drop the brightness below the standard brightness.

Lux is a pay app and reading description in market says nothing about dimming below stock settings.
Screen adjust otoh actually can lower brightness to zero can also modify color and contrast too. Best of all it's free. Been looking forever for something like this that works in honeycomb as lowest stock brightness is still too bright for nighttime reading for me.

Anyone have this auto brightness issue?

I noticed that my auto brightness will adjust and get bright when I turn on a light but then immediately when I turn the light off the brightness doesn't go back down. Anyone else have this? I'm guessing it's software?
Sent from my SM-G920V using XDA Free mobile app
Yes. I play with that by keeping my s6 under the lamp. Super high brightness levels.
I was just about to make this thread when I noticed yours.
Actually for me, I get low brightness levels it's very annoying. When I'm in moderate lighting conditions like normal lit room I get almost lowest brightness, when I move phone out in the open area, like outside, the screen lights up like it should, but in moderate lighting contitions it is very bothersome to have lowest brightness.
I'm now thinking of searching a good auto-brightness app. Any suggestions?

I cannot say any specific reproduction steps, but it looks like I have similar problems..
Galaxy S6 is my first Samsung device ever (before M9 I was HTC fan). Comparing experience with other devices I had - auto-brightness works definitely in a strange way.
Under direct lamp light - it's adjusted pretty much okay, but in a normally lit room - it's almost always too dark, and I need to adjust auto-brighntess level manually. So.. for me it's really not auto-brightness.
P.S. labas
So any other thoughts?

Same thing here. No solution so far. I tried to install velis from the play store, it is not working. I decided to return my edge emerald green ( ) because of this issue. In a normal lit room I get always low brightness, I have also the S6 flat to compare, side by side, and the S6 flat is almost at the same brightness if I set it at 50% and the edge at 100% (both in manual setting). Unbelievable!
I have S6 FLAT, and the autobrightness work ok if the phone are horizontal. But if i have the phone in my hand (in an angle more than 10 ° / 20 °) the auto brightnes bright the screen, but when i turn the light off the brightness doesnt back down. But if the phone are horizontal (0° in my hand or in a table, the brightnes bright up and down without problems)
There is a new 5.1.1 minor update available. Has this solved the brightness bug of the s6 edge by chance?

Just little different
I have a s6 flat and my screen is always on full brightness when auto brightness is on.
Tried the light senson and it seems to work fine (0 to 1 lux on dark room, 400 to 600 lux near to a light bulb). This problem started two days ago.

Same, here. Help us out guys.
auto brightness issue
I also got an auto brightness issue on my s6 flat version. Specifically it's about the adapting to low light conditions after being in high light e.g. turning on a bed lamp for a second (screen lights up) and after turning the lamp off s6 stays too bright and does not want to get back to low brightnes. The thing that helps is either lock/unlock the screen which makes it wake up with proper brightness or uncheck/ check the autobrightness box at the bar.
Is it commonly known issue that Samsung knows about or is there any possibility to get it back to normal on my own? It drives me crazy in a flagship device!

I have got the same problem and I'm dead sure it is a sortware issue. I tested the light sensor and it can update on different light conditions no matter the orientation is. I also installed Velis Auto Brightness app and it fixed the issues so Samsung should fix that since 3rd party apps can.
I too have the same issue. The brightness ramps up as its supposed to under bright light but doesnt go down under low light/no light unless i do one of the following:
1) keep my phone horizontal or at angle of >180 degrees
2) lock/unlock the phone by pressing the power button
3) manually tick/untick the auto-brightness check box
Really annoyed. I still under the return period so not really sure its a hardware defect or not
Well, unfortunately I'm facing the same problem :crying:
What are the differences to phones which do not have this issue repectively is there something in common who have this issue.
The biggest changes I've made to the phone are: Arrow Launcher (MS) and radiant theme (no root etc.)
I got the same problem, autobrightness adjust only when phone is placed horizontally. Any news in this regard?
unfortunately no
Do you still have this issue? Because I have it on every single ROM, Custom or Stock, no mather...
I have found the max_brightness adjustment, (sys/class/backlight/panel/max_brightness) but I can't find a similar file for minimum brightness. Anyone know it's location? At the moment I'm using a third party app as well, but would rather have the system fix.

Problems with contrast after unlocking screen

I've had Z3 since january and never had any problems with it. Yesterday I installed 5.1.1 Nordic build and while all went smoothly I have this problem with contrast or gamma right after unlocking screen. It goes all the way up, stays crazy for a few seconds and than goes normal. It is incredibly annoying. It is not brightness which goes way up, but contrast or gamma as it washes out the colors and looks horrible.
It happens only if Adaptive brightness is turned on, and no matter if it is dark or light outside. Tried playing with X-reality but no change.
I really have no idea what is going on, so any ideas are welcome.
Thank you for your time!
it's a known bug on the new .546 build
Ahh than I'm cool Thanks, where do you follow the known bugs and stuff? I searched here and didn't find anything
Yeah. I'm having the same issue with . 546, is so annoying
Oh yes me too, after 5.1.1, just turn off adaptive brightness. At least after the new update released
Edit: i thought the problem is only with notification shade pulled down, it's actually on all display?? Now it really is annoying to me, although not too much

It happens to me too .. I do not know what to do !!
.580 didn't fix this problem, nor the bold clock on the lockscreen.
This is not only since the .546 version.
It was there on 5.0.2. Atleast for me...

High Brightness Mode Widget

Hello, I'm looking for testers for High Brightness Mode Widget: https://play.google.com/store/apps/details?id=flar2.hbmwidget
have promo codes for the first five people to post here and willing to report back to me.
It will make your screen extremely bright at the touch of a button. However, it requires root.
Works on other Samsung devices with AMOLED screens, so should also work on the Note 5, but I would like confirmation.
Yes sir

I had a couple extra codes, so all of you got one.
Took a couple of installs to get it working but afterwards it works great. Haven't had a chance to run AutoMode yet due to it being 11:45pm...lol. Will run it tomorrow in the daylight on auto and report back. Thanks again for letting me try this out...greatly appreciated!
It works great!
Just like everything you make.
I always enjoyed the kernels you made for my htc one xl
i tried this on my Note 5, i noticed some lag when turning it on and off sometimes, like the button wont click at times, have to press it twice to turn it on and off
Everything works fine.Latest MM stock rom.Thanks Dev.

Nothing I can do about that, it takes some milliseconds to turn on.
Becaue of that, I made it so if you tap a second time within less than a second it does nothing, just so it doesn't go on and off quickly from repeated taps.
Tapping twice within 200milliseconds puts it in auto mode where it will come on automatically in bright environments.

ah ok, nevertheless great app!
Can anyone confirm that the screen gets really bright with this widget enabled? It should be much brighter than if you simply move the brightness slider to max.
It gets a little brighter, not as crazy bright or whatever happens when outdoor mode kicks in but it gets brighter indoors.
***after testing on my note 5 with lux meter from the playstore (on my note 3). I have some results that are slightly more useful than just my eyeball tests***
HBM off
420 on full brightness indoors
590 on full brightness when outdoor mode starts
HBM on
450 on full brightness indoors
590 on full brightness when outdoor mode starts
But when outdoor mode turns off after a few seconds it goes back to 420 and you have to toggle HBM to get it back to 450
Samsung has some weird settings they implement that seem to be affecting our screens performance.

They also have a weird way of having autobrightness work differently when you are holding it compared to when it is laying flat on a table. So they have pretty much F'd with the way google intended everything as usual.
