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.

Notification Led diode

Hi guys!
Iam having a problem with notification led diode. It doesnt work. I havent seen the light yet.
I just tried Light Flow app but it also wasnt able to light the led up.
So i assume that my phone is broken in that part and the diode just doesnt work on my Nexus 5.
Does anyone have some the same problem?

Figured it would be but had to ask. Factory reset as a last resort maybe?

I installed Light Flow. Took a few minutes before I got any lights.

There's a test mode in light flow. Might be worth trying that too.
Sent from my Nexus 5 using Tapatalk 4

Test mode in LF didn't work for me. I was going to uninstall but then I noticed the battery charging light came on. Now all of the programmed lights in LF work for me. I have not retried the test light feature.

light flow might have just glitched up the led for a bit. If it stops working again, try clearing app data, or reinstall, or uninstall light flow altogether. It has been known to have some issues.

In light flow you have to turn off the screen after turning on test mode, if you haven't tried that already.
Sent from my Nexus 5 using xda app-developers app

Yes, the screen MUST be off for the notification light to illuminate. In addition, at least for Light Flow, it can take several seconds for the notifications to light up, even when performing a test.

Same problem here and it's going to back for a refund. It was actually a replacement unit for the first one which had speaker issues.
I tried everything and never saw the light come on once while the first unit worked fine with the same settings.

try this
Hey guys I was having this same problem but I downloaded this app called notification light widget by Motorola and added it to my home screen activated it and my notification light has been working since just tuck the widget away on a side screen . its a good fix for now

Just tried it on my phone thats going back tomorrow and it didn't help sadly.

LED Inconsistencies

Anyone else noticing any LED notification inconsistencies? It seems the LED has a mind of its own. Sometimes shutting down the phone and restarting seems to help, other times not.
I'm on pure stock and version 4.4.2.
I'll get an email and get no notification at all. Then I'll get another email (same application) and then get LED notification. Sames goes for SMS. It just seems so sporadic. There is no notification ever for missed calls at all.
I've tried programs like Light Flow and Light Manager, but really don't want to pay for the pro version of Light Flow to make my LED work as it should and Light Manager seemed to conflict at times with certain apps.
The LED notification is one of the most important things to me. It just needs to work and work all the time. Seriously thinking about trading my Nexus 5 for an LG G2 because of this.

Op turn off pulse notifications in settings reboot phone and than turn it back on and reboot.

Pretty sure I've done that before, but I'll give it another try. Thanks.

Sorry can't provide a solution, but I can confirm that I've had that issue on CM11 and SlimKat. But then I had it on my GNex with various ROMs sometimes too. I had just kind of resigned myself to the LED doing its own thing...

Well, it's not working as it should. What good is an LED light for notification if it works when it feels like it. I explained why I don't want to use either of those apps. Again, the LED light should work properly. It doesn't. I never had any issues with the LED on my GS3. It worked all the time without issue.

Every phone has its issues. I know it doesn't help but for the record I do not experience these issues. Never installed Light flow as the default functionality "just works" and even blinks more often since 4.4.2 I hope light flow isn't causing more issues then it helps.

L.E.D off times??

Is there anything that I can use to turn the led notification off at night time? It's really annoying having it flashing in my room at night time when someone does something on Facebook or a Gmail arrives etc

I use Silent Hours.

Maybe try this? http://forum.xda-developers.com/showthread.php?t=1803130

I like Do Not Disturb.
Not only does it control the LED, but it can control all your sounds too. You can set quiet hours, and it can even access your calendars, so that it can automatically set quiet time during meetings. It has separate day and night modes, so, for example, you can have it vibrate during quiet times during the day, but be totally silent at night. You can also set exceptions, so that certain people can call or text you during quiet times.
Works awesome.

I've found ledblinker on the play store. Looks good! Anyone tried it?

Try placing the phone face down at night.

LED off in Slient Mode
I know this is a fairly old thread, but I noticed the LED on my Nexus 5 does not blink when it is in Silent Mode. Is this this behavior normal? Shouldn't the LED blink regardless of the Sound/Vibration settings?

I put my phone on silent every night and the LED still blinks.

I use Trigger. I started using it for NFC tags but recently bought it for the other features. One thing I do is set a trigger at 10:00 PM, Sunday through Thursday, that puts the phone on silent and turns off the notification light. Then at about 6:20 AM, it does the opposite to turn them back on.

That's really odd...
I tested it a few times and no matter what I try, the LED does not blink when the phone is set to silent (No sound/no vibration). I mean, it's great, because it keeps LED notification off at night, but I wish I could find out what makes it behave that way.

Lightflow used to blink even when no notification arrived. Sometimes. So I switched to ledblinker. It's just perfect, reliable and has the ability of "sleeping time"

You're not alone
I've had a similar issue when I've had "Smart Network Switch" enabled. When the phone paused, I was pressing the back button but nothing happened, then I got like a very rapid buzz sound from he speaker (like from pressing the back button lots), and then it was working again.. Just turn SNS off if it keeps happening. Its a bug, hopefully it'll be fixed in the next update :good:

I had the same issue two times now, all network connections drop, the phone vibrates, then freezes for about 4 seconds. After that everything comes back to normal.
Edit: Smart network switch is disabled, that doesn't seem to be the problem because mobile data also drops during the freeze.
