Notification light

Hi Nexus 10 owners,
Love my Nexus 10 but I have an issue with the notification light under the screen.
It was working fine when I first got it on Friday, with it dimming on and off when an email is received.
But since yesterday, it hasn't light up at all, for any notifications, and I do have the "Pulse Notification Light" checked in setting.
So I was wondering if anyone else have any problems with the notification light? Could it be a bug, or perhaps my light broke after the first day?
Thanks in advance for any response.

I might suggest trying https://play.google.com/store/apps/details?id=com.coolbeans.ledtester&hl=en to see if your light still works

Thanks for the suggestion.
Just tried the app and there's no light.
However, could it be that this app doesn't work on the Nexus 10 yet?

Yea it might be possible that app doesn't work; may want to see what an actual N10 owner has to report though

Works fine on my N10, only flashes white though, regardless what colour I pick.

So I guess it's really just my N10 then.
Thanks though.

No problem, try reflash with stock images and you might get lucky. My Nexus 10 is buggy as sh** and I put it down to 4.2. It'll all get sorted out soon enough, hopefully yours is just a bug too. Hope you solve it.

UPDATE
Just reset my N10 and now the notification light works again.:victory:
Guess it must have been one of the app interfering with the light.
BTW, when I tested it with a LED tester app, it can actually show green, red, blue and purple lights.:good:

If I understand right, he just flashed a factory 4.2 image from Google, without any OTA updates.

You can get the factory software from the Google developer site and you can download it to your nexus device in case anything gets messed up.
By "put it down to", I mean I blame 4.2 (Android version on the Nexus 10) for all the bugs I'm having. It's a new OS, and this multiuser stuff amongst others means some pretty major changes so I expect it to be a little unstable for a while. Still a better state than honeycomb was when I bought my XOOM on launch day, boy was that a mess.
You're right about the lights, I just got it to work with all the different colours, cyan and then purple look nice

Wow, I did not know about the factory software from the Google developer site. Guess i learned something new today. :laugh:

UPDATE #2
The notification light is not working again
Reset my N10 again, then performed a LED light test each time I install a new app.
Until the last app installed, the notification light was working, then after a few minutes it stops working again.
So I guess it's not really caused by 3rd party apps.
So I ask again, has anyone had problem with their N10's notification light?
Still hoping that it's a bug instead of just me having a defective unit.
Thanks again!

I'm having the same issues. Sometimes the LED seems to be working, others it's not. I installed LED tester and again, sometimes it works fine and others not at all. I have tried to spot a pattern to see what causes it to stop and start and have drawn a blank - no idea. I have since installed light flow but this has not helped. Seems to me that there is either a software bug and we haven't yet figured what the trigger is, or there is a dodgy hardware batch (I hope it's the former!)

I think I've found the trigger. If I turn the device completely off, and turn it back on with the charger plugged in, notifications work. If I turn it back on with the charger unplugged, notifications do not work.
Other things I have tried which made no difference included factory reset and factory reflash.
Can some other folks see if their behavior matches mine? I have a replacement device being shipped to me, but if this is a software problem I'd rather not swap hardware. I'm very curious to hear if there are any devices that have a working LED under both boot up scenarios.

I think you are right. LED notifications were working ok when I had a freeze in google now. I restarted (on battery) and tested the notifications - no LED. I plugged in the charger, restarted the system and retested - LED working again. Looks like we have a workaround and a confirmed software bug rather than a hardware fault.

I'll test when I get home, but, I've only ever noticed the light when my tablet is plugged in, so it could be the same for me too. Shouldn't be a major problem, will get fixed in the next update as long as Google are aware.

I'm not entirely sure, there are people who are claiming that their LED works 100%.

Just tried this but still nothing.
Called Google today and they are sending me a replacement.

Ok, this is ridiculous.
Just unplugged my N10 and now the notification light is working.
So apparently it's working randomly.
Hopefully my replacement device works 100% of the time.
BTW, are replacement devices new, or refurbished?

My brightness slider and auto-brightness DO NOT.

And more specifically and as far as I can tell, if the phone is freshly booted then the functions listed above work. However, after several hours on I go to adjust the brightness and the screen does NOT change its brightness no matter whether i set auto-brightness or adjust it manually.
Let me preface this topic and let you all know that I still have my stock screen protectors attached and I've installed the light flow app if that matters.
Any ideas?
EDIT: I such at naming titles.

same here, just wiped. no clue what's causing it

Same for me I just noticed this. Hope its something fixable in an update.

It doesn't make a difference if I use lightflow or not it just won't act right.

Have you tried wiping? I haven't had any issue since

Ugh never mind, brightness got stuck again.

Wow am i glad to have found this thread, i have been battling this problem since day one with this phone, and i have been trying to track it down with usb debugging but have been unsuccessful. What happens is that my screen will randomly shut off and be non responsive for 5 seconds and when i can turn the screen back on, i can no longer adjust the brightness and only a reboot will solve the issue. It also occurs when i am not using the phone so i think it is a hardware issue but i am uncertain.
Things i have tried to fix it:
Factory reset
Fastboot flash factory image
Flash cutom ROM & Kernel

Didn't realize it before but yes, my screen randomly turns off, then the brightness gets stuck. Thought it was timing out
---------- Post added at 03:52 PM ---------- Previous post was at 03:46 PM ----------
You guys use auto brightness? Maybe that might be it

This happens to me occasionally too, haven't been able to determine what triggers it. It's almost as much fun as the magical battery levels. Plugged in the other day, went from 4% to 100% in a nano second.

interesting...my auto and slider work just fine

ugh still getting this problem daily. does't matter if auto brightness is on

There is no solid way to reproduce the problem, so I am willing to bet its a hardware issue. I will be calling T-Mobile this week to replace it.

Of the people who are experiencing it, how many have a notification drawer widget (Widgetsoid, Power Controls, et al?) and have a brightness toggle on it?
I've removed brightness from Widgetsoid to see if it's a conflict of some sort.

Yes I'm using power controls. Still does it even if I disable the brightness toggle

Might be a hardware issue? If it was software I think a lot of people would be complaining about this.
Edit: ugh as I was typing this post, screen flashed and turned off with broken brightness. I just rebooted like 5 min ago too

Not sure. Here's one report on Google Code: http://code.google.com/p/android/issues/detail?id=40378
Edit: could just as easily be a OS issue, if it decides to stop polling the light sensor for some reason. Many people have the battery bug as well, which seems to stop polling the battery for some reason.

[Q] LED Notification

Hi,
I've finally received my Nexus 4, and quickly upgraded to Android 4.2.2
One thing I noticed is that my notification LED does not seem to light up when receiving email from the Gmail app, nor does it light up while charging the phone using the LG charger.
Edit:I've just noticed a white LED notification for email... I didn't notice it before because it was very low-key and had a large time interval.
Is it supposed to be like this, or is the phone faulty?
P.S. Does the LG charger make a rattling noise for anyone else when it is not connected to the phone?

I know that the LED is not supposed to light up when charging (some custom ROMs have this feature though) and the charger "rattling" is a known issue.
The gmail thing is software side, for sure. So I'd say your phone is fine

the led notifications on stock rom aren't that great. they have a very long pause in between each flash so it's hard to see.
download and use lightflow. i purchased it from the play store and it was definitely worth it. you will get the ability to customize how and when the led flashes and for which app you'd like to receive notifications from.

I hated LightFlow on my GNex, and I still hate it on my N4. I much prefer CyanogenMod's custom LED notifications. They actually work like they're supposed to, and don't get stuck on.

Light Flow works great on my N4. Have a look at the thread on it in the Apps forum, you'll see the number of people having problems is very small.

If you use light flow make sure to use their widget because with out it you will think that it was staying on when you didn't mark am e mail or sms read.

LED notifications not working....

Hey all. New Vzw G2 here. I have clean rom on this right now and just loaded up aicp as well and neither rom has working led notifications. The led works it charges red, blinks green on boot up, and flashes white on waking up the screen with double tap.
I have tried multiple notification programs from the play store and tried to test out the led but nothing is working...
Am I just missing something obvious here??
Any help would be appreciated.

I know that this sounds like a no-brainer, but we sometimes forget to check the simple things. Check your settings under display and make sure you have the notification switch "on" and then download and try light manager from the play store.

The only thing I could figure out to get LED notifications to work was to use a 4.3 based rom which has the proper API's for notification apps. IMO I traded the IR functionality for one which lets me setup my phone to actually have notifications. No idea what the AICP rom is since I have a D801 and the VSW G2 is all different for whatever silly reason but Light Flow works great on PA.

Thanks all still no such luck. So weird. Enabled and disabled the notification in display tried light manager and light flow still no go. For real I don't get it. I know the light works but only for system notifications like charging battery low knock on etc. SO weird. Grr

Can you test a different rom?

I've tried aicp and clean and I'll try another here soon. 4.2.2 hasn't worked and an AOSP 4.3.1 hasn't worked I can't figure it out.

Could my issues be anything to do with still being on the most recent stock firmware baseband? I have a rule now to never accept OTA updates after my S4 screwed me over. I thought I read there was an OTA for Verizon at some point....

Have you tried backing up your data and trying the stock rom? I've also noticed that some things don't function properly on some custom roms, especially if it's not stock. I know you said you've tried other roms, but at this point, it just has to be checked through trial and error.

Make sure Pulse Notification Light is enabled, Use custom values is disabled and Battery Light is disabled. I have Root Mode and Reset color before change enabled on Light Flow and anything else significant disabled.

For the stock rom, Google backup was screwing up with the led notification. I had that problem.
I disabled Google backup and wiped the phone.
During initial boot when it says to back up with Google I deselected it and the led notification worked.
Not sure for custom rom.
Good luck

Hmm! Well, I am going to try this. I have plenty of TWRP backups, I'll run a fresh install and see if not using google restore fixes the issue. If it doesn't, I'm STUMPED!
I sure hope it works, this is the ONLY issue I have, I LOVE this phone otherwise, but this is a pretty big issue, I never know when I have messages waiting!

HOLY CRAP - If I could THANK you a million times I would. Deselecting restore from google WORKED. Booted CleanROM up as a fresh install and tried out the lite version of LightFlow, and BAM, LEDs worked. Must have brought some setting over from all my Samsung devices I owned previous. Never had an issue going from the S3 to Note2 to S4, but going to an LG, must have had issues.
THANK YOU !!!!

Seriously! I was about to try to return my phone, that would have been a hassle and a half. I LOVE my G2, Best phone I've had, I wish there were more cases for it for the Verizon version, I'm a minimalist guy and there is like one case on ebay that fits that bill. Oh I digress!

I switched from GS3 to G2 and let Google restore my settings and apps. My Light Flow (and Light Manager and every other LED app under the sun) just would not work. I just couldn't figure it out... it worked just fine on the GS3.
Finally, after disabling the auto restore of settings and apps, I did a factory restore; and now Light Flow works. Well, my email insists on green rather than the colour I set for it, and I can't seem to get the calendar notification LED working but everything else LED related now seems to work (mostly all 3rd party IM apps) including charging, charged, sms, etc.

Received New Software Update

I'm assuming this is for the red tint? But at 141mb, there's got to be more than that. Anyone else got this?

Got it too, think it's the update to allow for the screen color fix

I got it too. I am on T-Mobile

Yeh

On Verizon, just checked and nothing for myself.

After this update I completely lost any capability to adjust color balance , including blue filter. I had to go to vision, TURN OFF color adjustment????? to get the settings back. Not sure whom am I angry more at.

In the "Screen Mode" options you have to check "Advance Options", scroll down and you'll see the color balance. Kinda weird they did it this way.

Are all these updates worth doing before we know anything about rooting the device etc? Like would any of these updates hurt us on any possibly future exploits to patch something up and unlock? I havent updated my device since I got it.

Anyone using package disabler. Remember to enable all disable software. Cause if nlt. U might end up in bootloop after the update and the only solution would.be a hard reset.

Heard this update is causing battery life changes :-/

I got the red tint update this morning on my S8. Installed it and for me it made no difference in the range of adjustment for totally getting rid of the red tint issue. The edge red tint on mine is always there. So for my S8, no difference. slower Wi-Fi file transfer speed that I've mentioned in my various other postings is not improved either. Still the same. Oh well.

Got it 5 days ago in Qatar.
Just color settings. (including edge only color control)

Actually I think I know why they did: so people don't go to the menu, mess things up and then complain screen doesn't look right.

I think it's only a T-mobile issue OR it's only been released on T-mobile phones at this time

How could that possibly be declared just hours after the update has started to roll out? "Well my battery went down 3% instead of 2% in the span of two hours so this update must effect battery. Oh noes!"
