Nexus 5 auto brightness problems?

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] screen visibility

Need some guidance, I have a Transformer 300 and having terrible visibility with screen. Screen Brightness is on 100% and have auto brightness turned off. Can view inside okay not great. Outside impossible even under shade. Only visible with complete darkness. Is this a hardware issue that I can fix? My eyes are starting to strain. I had to have screen replaced a few months ago. Could damage now be showing up?

Try an apk called Lux. It will over ride your tablets normal max screen brightness and Max it out to the device's true max. I use it on about 4 devices including my TF300T it's awesome

Led light

Just curious if anyone's notification led has went dimmer. When I got the phone it was bright but now it's dim and I'm trying to figure out why.

Dim notification light is randomly occurring on my phone. Sometimes bright, sometimes not... trying to correlate a specific action on my part (auto screen off, etc) triggers it...

The notification LED obeys the ambient light sensor on the phone (it has its own auto-brightness, essentially), so your experience might be due to that.
If I am in a dim environment and I get a notification, the LED comes up very dim. If I am in a bright environment and I get a notification, it comes up as very bright. It also worked this way on the Note7 and S7/S7 edge.

Makes sense as to why it's so random.

any way to customize the colors? i use to rock lightflow back in the day but not sure it works for this phone.

I have just found a method to get the led always shining bright, weather in pocket or dark !!
I was about to return the phone because of the dim led issue but then put my thinking Cap on and managed to fix the dam thing.
You just need root and Light Flow.

Happy bright LED.
Cheers.

Be hyper careful i saw some threads where lightflow was able to make the led stop lightning. Only hardware fix was able to bring it back alive. This happened on various s8 and s8+

I had my led light module replaced as it stopped working. But not sure if Lightflow was responsible...

I remember reading the producer of the app lightflow
Hade to change a value in the app code making the led going broke.

A lot of users reported that the LED that seemed to be broken was fixed after an update from Samsung. Most likely a software issue. I have been using Lightflow and Lightflow Legacy (most recently) with no problems. The legacy version is recommended for the S8.

Anyone else is using Light Flow again? I have been using it since S3 with no problems at all, but now my notification LED went off at second day until last firmware. I know the problem was not due to Light Flow but maybe the software failed more easily in presence of Light Flow. Now I am afraid the problem only could be partially solved and still sensible to Light Flow software commands.

So what settings did you use to get lightflow to always show a bright led... I have a S8+ and a S9, both rooted.. Both with Lightflow and no matter what settings I try I can't override the ambient display.

It is clear that your mobile phone has a technical problem that needs maintenance, but try to return it to factory settings

maybe i use app that make the phone to hot the the screen dimm?
im using whatsapp facebook instagram and messanger maybe? anyone knows?

On the Flip 4 I use the Adaptive Brightness "on" setting, and Dark Mode. Your results may vary, but here's what I've seen.
In the summer, on a sunny day, I'll notice that the phone will automatically try to be as bright as possible, so the screen is readable. (I'm pretty sure when this happens the quick display panel's screen brightness slider color changes to orange. Maybe the color depends on the wallpaper/color palette.) And I never see the screen do this "extra bright" thing indoors. Only outside and only in direct sunshine.
So far so good. I think this is as everyone expects the phone to operate.
Given all this, sometimes I'll notice the screen brightness will vary, even though I'm still outside and still in the same brilliant sunshine. I've noticed this commonly when checking Google News, and for example, I'm reading a story and scrolling slowly through the article. In particular when the screen is mostly black text on a white background.
So, in this situation, that is, a largely bright background, in the bright sun, my phone will both:
Get warm to the touch, on the back-side of the phone, where the two batteries are, but not up where the cameras, CPU and memory are located. This makes sense because "scrolling text" isn't that demanding on the CPU, but I am driving the OLED screen hard.
Also the front of the phone (the OLED screen itself) can feel warm. Even in the screen's crease, away from the battery. Since the image is mostly white, all the OLED dots are "on" and give off heat. Then again, I'm in brilliant sunshine and almost any surface will get warm.
Further, I'll notice that the phone screen will automatically get dimmer after a bit of time (perhaps a minute or two of extra-bright before the dimming). This I attribute to the software doing one, or both of:
Dialing back the screen brightness, to prevent OLED burn-in.
Dialing down the power usage by the screen, to prolong battery life and/or limit the battery temperature.
What's more, after little more time, still in the same bright lighting conditions, perhaps reading the same story, the screen might be noticeably extra-bright again. It's as if the phone has given the display "a rest" and is willing to go "extra bright" again.
In short, I think the phone screen is trying hard to be brilliant in the brightest of sunshine. But there are limits in how hard you can drive an OLED screen, and how long the battery can power the screen.
All of this before we start to talk about what design limits come into effect when the CPU or graphics processing come into play, both or which compete for:
Power from the battery, and
The ability of the phone to keep itself cool.
This phone's form-factor is all about folding in half. A slab form-factor phone, I suspect, will be far more capable for heavy CPU, graphics, and provide a bigger battery and better heat disipation.
