Nexus 4 dim notification LED? - Nexus 4 Q&A, Help & Troubleshooting

Hey there, got my N4 this morning, its a good upgrade from the GNexus. I haven't had any problems so far, besides the GMail not syncing and the lack of a LED notification light. Or so I thought at first, its actually on, but incredibly dim, so I didn't even notice.
Is this just me?

It appears to just be you, my notification LED is rather bright, actually. Have you tried tweaking it with a third party app from the Play Store?

Its dim in comparison to the Samsung LED for example the LED on my Note 2 is a lot brighter and more vivid

Thanks for the replies. Its very dim, even when I tried using Light Flow. I haven't installed any other app that may interfere with it.
In addition, my GMail syncs really slow.
I'm currently re-flashing the stock rom and maybe it'll be fixed.
Thanks

No your not the only one.. Did flashing the stock ROM help you?..
I notice mines is dim compared to my gnex

Its dim and it blinks unbelievably slow. I dont understand what they were thinking. Notification lights should be bright and obnoxious to.... notify you.

Has anyone found a fix for this yet? The notification light on mine only blinks once then stops. How is this suppose to notify me if I missed a message if it only flashes once and is extremly dim. The Samsung Led light are are way better. Is there going to be a patch for this problem?

Hello fellow RFDer - to the OP

I used light flow with the custom flashing rate, set at 1000/1000 (so 1 second flashes with 1 second gaps) and it seems to work well. Setting any of the other settings (slow - fast) didn't make a difference. I really can't wait for CM where all these items are built in and we dont have to mess with 3rd party apps.

It worked for a while yesterday, now it stopped working. I've since installed Light Flow with no luck, have Light Manager right now (all free so far), but still without success. I've always been a Blackberry person and had a GNexus before, so I'd be lying if I said I wasn't spoiled with a working light.

Agreed, I'll be keeping an eye on this thread to see if anyone has any recommendations.

Same thing for me, notification light worked fine the first day, then I rooted the phone and now it's very dim. LightFlow did not improve anything.

Hmmm I noticed my light is super dim as well just like the pictures on the first page. Unlocked and rooted it before I got a notification though.

Agreed it's dim.
The LED appears to be under the plastic in the bezel rather than displayed through a hole cut through it. Not sure adjusting brightness at the software level will have much of an impact.

My led is dim as well
Mine is dim and glows really slow! Using Light Flow now, but still not as bright as the one in GNex.

Hi all,
I have a similar issue:
My LED light flashes only when I get notifications relating to Facebook & Whatsapp.
It does not work for missed calls, Gmail messages, text messages or while charging!
I had installed Lightflow and it was a little buggy, but I think, the LED notification should still work for all types of notifications?
I have also factory reset the phone and have the pulse notification option under the display menu turned on, but still no success.
Any help/replies will be much appreciated.

I have no issues with using light flow.

Thanks mate, how about without light flow? Does lightflow drain a lot of battery?

Light Flow only drains battery when you leave a notification unchecked for long periods of time (i.e. the notification LED flashes for long periods of time). Naturally, the longer the LED flashes, the longer the wakelock.
In normal use, the battery hit is negligible (in my opinion).

Torch apps bad for LED light?

Will using a torch app kill the longevity of the LED light?? I thought I heard this before somewhere but I'm wanting to install the Nexus Torch app on my N1..

@Krumb
Thanks for the link.
But the discussion stopped in April, pre-froyo.
Now that G has enabled Led-on Video recording in Froyo, I am curious to know if any one faced issues while using it for prolonged night time video recording.
I personally used it for a max of 5 minutes continuously, for video recording as well as for use as torch, faced no issues.
I think the light is fine with 'normal' brightness for extended use, but not the ultra-bright setting.
LED light has "lifetime" - which is, it's built to last X hours on average.
Each time you turn it on, you take Y seconds out of its lifetime.
By analogy, each day you live, you're 1 day closer to death. You don't stop living to avoid death, do you?
Yes, the LED will die one day if you use it. If you're not unlucky, it'll be way after your phone turned to a piece of junk. If you're unlucky - it can die the next time you turn it on. Pure statistics of semiconductors, can't predict it.

Consensus on Smart Stay battery hit?

It works well as advertised. Just wondering if it's taking a toll on the battery life.
I doubt there's any noticable hit on the battery - "smart stay" is only active when the phone's screen is already turned on. Compared to the power drain of the screen, flicking the front camera on for a few fractions of a second every 30-60 seconds is meaningless.
It doesn't work well for me. I see the eye pop up in the notification bar, then my screen goes dim, then off.. while I am reading a web page or xda. What do you do to make it work?

That happens to me in low light. Sufficient ambient light seems to be requisite for it to work. Other than that I'm not sure.
It seems not to like my glasses. I watch the eye flash on and off, then it goes dim anyways. no tinting, just regular glasses.

Works fine for me, maybe you were blinking or something.

I haven't noticed any difference in battery life with disabled vs enabled. Works great for me (as manual states, must not be in low light otherwise will not work). Works with my glasses on as well.
Battery hit should be minimal. I use Face Unlock which uses the camera and the battery drain is negligible.

Faulty Light Sensor?

Has anyone had any problems with the light sensor on their Nexus 6P?
I've noticed that it works fine if the light is shining directly onto the device, but it's not so good at picking up ambient light.
If I put my Nexus 6P and Nexus 9 flat on my desk at work, I get a reading of 225 lux on the Nexus 9 and 226 lux on the Nexus 6P - basically the same.
But if I pick up both devices and stand them upright on the desk, the Nexus 9 shows 90 lux and the Nexus 6P shows just 36 lux.
Most of the time this isn't a problem, but if I'm using it somewhere where the light levels are borderline and change a lot (like on a bus or train at night) I find that the device ends up changing the brightness a lot because there's not much light directly shining on the screen.
I've been using the free App "Sensors" from the Play Store to check the light levels - https://play.google.com/store/apps/details?id=com.calintat.sensors
Has anybody noticed anything similar? I'm running stock on build MDA89D (not had any OTAs yet).
I am seeing the same behavior with my 6P. Borderline light conditions at all, and the brightness is constantly changing.

Could you check the readings you get from the light sensor when it's happening?
There are lots of apps that will let you see the sensor readings.
I noticed this last night in a dark room with a few lamps on -- the brightness would just randomly increase and decrease.
Yep, was sitting on the couch last night reading in a moderately lit room and the screen would randomly get bright and then dim again. Got so annoyed that I turned off adaptive brightness and will just adjust the screen manually. My biggest complaint with this awesome phone.
Nothing to add except that I also turned off adaptive brightness as it wasn't functioning properly and was pretty annoying.

Would you be able to try and get some light sensor readings in that same location?
I'd be very interested to know if it's the same cause as mine.
Same thing here with the low light. It kept going bright and slowly back to dim where it should be.
Same issue. This and being virtually unable to use the phone in direct sunlight are my only two gripes.
Watching the sensor as I move around it bounces all over the place where as with my S5 the sensor readings appear much more constant.
Same issue, I wonder if it's software or faulty device
I checked out the light sensor In the lux app as I was having a similar issue, I can see the sensor go from 1 lux to 11 even though it's in a pretty dim room at night, it keeps changing...
Same for me.

+1 for this issue, when playing games in a brightly lit room, my brightness on the phone keeps constantly changing, even though I always hold my phone in the same position while playing.
I ordered replacement and will check

Would you have any source on this, I'd love to get this better as it's pretty god damn annoying. I'm sure it can be fixed with a kernel or xposed module.

Longevity of notification light used as a battery light too?

A lot of ROMs and apps now let you use the notification light as a battery light.... It'll show when it's charging, charged or getting low. I put my phone on a charger at 11pm and take it off at 7:30 or 8:00am, so that's about 9 hours every night. I also, usually, throw it on the charger at work for a few hours at the end of the day to give it a 100% charge for the trip home (or while in the car I charge it). That's not counting all the text and email notifications I get that make it blink all day.
I question the longevity, or durability of the light? Are these generally long lasting LED bulbs? Not sure it was meant to be used as a charging light?
I'd rather sacrifice a little now, as far as cool lighting effects and still have a notification light in 2 years (if I ever kept a phone that long, or when I give it to my son), rather than burn out the LED and have nothing in 2 years.
Am I over thinking this?
I'd imagine it'd be fine. Just look at pretty much any modern-day Samsung phone - they use the LED for charging indication by default. I also have my 6P set up like this since I liked that feature on my Note 4.

I've never seen one of these LEDs die.... Not saying it can't happen, but even on some nearly 4-year old Galaxy S III phones, the LEDs still work
Why would it die? I always set these on my older phones and they work like new, not even the brightness dims.
LEDs are built to last, AMOLED isn't

[Q] Phone vibration on screen lock/screen off

How can I turn this off? It's driving me crazy. It does like a double vibrate very time the screen times out or I hit the power button to turn it off...

I've got the same issue with vibrations. When I disabled notifications for Light Flow it stopped.
Contacted the support for Light Flow and got this answer:
Hi
I'm aware of this from other users and so yesterday I ordered a oneplus 5 to specifically look into this. It should be delivered early next week and I'll then be seeing what I can do.
Cheers, Andrew

Thanks, lets update this thread when we get a better answer. Subscribed
Subscribed. Having this problem as well with Light Flow. Hopefully he can figure it out! Would also be really nice if he could figure out how to control the blink rate as it doesn't seem to make a difference what the rate setting is in Light Flow.
This issue happens during a call too with the proximity sensor leaves the ear enough to turn the screen on/off.
Will you please keep us up to date if you have further communications with the developer of Light Flow and hopefully pass on the feedback on blink rate?
Update available, fixed the problem ?

Does repeating sounds or repeating vibrations work for you?
Led works fine but those 2 not.
