Light flow

Does Light flow works fine for you guys. I just have a small problem, when I turn on the pulse notification light, light flow works fine fine but I see the white light blinking all the time when the screen is off. If I disable pulse notification light to get rid of the white light, light flow stops working

I tried Light flow once and it made my touchscreen not respond...

Wasn't working properly for me. Kept flashing the gmail notification whenever the screen went off, so I just disabled the app altogether for now. Works fine on my N4 though.

I'm having problems with light flow too but I'm not sure it's a problem with the app. Before I installed it I was having intermittent problems with the LED and I don't know if these are the cause of the light flow problems. I have contacted the vendor to see if they can help. My issues include LED sometimes not working and notification sleep periods not working. You might want to try the LED tester app to see if that sheds any light on your problems (no pun intended!)

Light flow will flash a with led if the apps logging function is turn on.

For everyone having the problem on the continuously blinking white/light pink LED whenever the screen is off: It's from a notification for "No signal" which apparently applies to cellular signal, so unless they change this to include a Wifi signal then this notification will always blink on our wifi-only devices

It works for me but in my gnex it produces a solid light and in the Nexus 10 it blinks... Is there a way of making it solid in the N10?

Go to the notifications, click on an individual notification, go to the light tab, then change the LED flash rate to your liking.

My light flow is sort of working. It is blinking for the apps I have it set up for, but not always the color I have chosen. I think this is do to an Android 4.2 thing, not so much as the Nexus 10 itself. I am finding several apps that do not behave properly with 4.2.

It seems some colors don't work. I had orange selected and it showed white for my notification. I changed it to bright pink and now it shows that color just fine.

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.

Will try at the end of this battery cycle then and yes it clearly looks like a software bug.

Ok i test it with Led Tester. Cyan looks nice ^^

Notification light?

Is the LED below the screen supposed to function as a notification light? I ask because I haven't seen it light up even once for anything. Not when charging, nor when there are new emails, messages, etc. Heck, does it work at all?

I see the notification light blink white when I have a new email from Gmail. Do you have Settings->Display->Pulse notification light enabled?
I guess you should make sure you have email notifications (do you hear sounds?) on as well.

I to have yet to see this notification light. I do have Pulse notifications enabled and yet nothing happens when charging even after the device is turned off and charging. I'm unlocked, rooted, stock, with CWM recovery.
Edit: I also do hear the notifications when receiving emails just not the light notification.

Yes, my pulse notification setting is on. I get the audible tone that I have email but no light ever.

You guys are not alone. There is another thread on this issue. Seems that the LED, for some of us, works sometimes but often does not work at all. There is an app called LED tester (free) that you can use to see what the situation is with your LED. Note that installing Light Flow is not a solution - when the LEDs are not working they will not be working under Light Flow control. So far I haven't been able to spot what triggers the LEDs to start or to stop working. Restarts seems to have no effect. With mine, when they work they work for a day or two then abruptly stop and stay stopped for a day or so.
A number of people seem to be affected by this but there is no indication yet whether this is a software bug (hopefully) or a dodgy hardware batch.

Mines been working since day one... Installed light flow and kept on moving

I've never seen the LED on mine, LED tester does nada! I'm hoping it's software but ultimately not too concerned, not a feature I care too much about.

Where is the light supposed to show up?

My notification light works, alas on both the N10 and the GN it *never* blinks on the first notification it should report after a reboot. From the 2nd time onwards it works as intended.

Didn't even realize this had an led...so guess mines never lit up either

The notification light only blinks when the screen is off and a notification is received...

By default, the notification lights only show up when the screen is off... and the moment you power on and reach your lockscreen, they go off... in my custom ROM, I have an option to enabled the notifications lights when the screen is on as well...

No kidding, I had to go look in the little book to see where the led even was!

I disabled it due to constant pulsing...mine works TOO good.

Looks like mine doesn't work. Even after using light works app. This may push me to exchange this now along with light bleed problem that is pretty visible.

Pulse Notification Light

Hi All,
Is there actually a notification light on the 2nd gen Nexus 7? I've yet to see it light up. I have the box in settings checked off, but nothing.
Any insights?

Also In order for the light to come on, your screen has to be off.

Is it only white? Light flow can't change the colors.

Oh, the things you learn in the XDA forums. I had originally thought that the notification light setting was a dead end, and immediately imagined how nice an LED pulse light would be on a tablet. Coming from the light-less ASUS TF300 that I just sold off for this... Absolutely brilliant. Placement on the tablet is a different story though...

Yeap mine work with all notification .
Hate only white though, should have more choices out of the box.

Try the app yourself.

you can't change colors. it's only a white led.

So, does it have a multi color led or not?
I'm interested in the new nexus 7 but notification led is a big deal for me :silly: as my current nexus 7 doesn't have it and I wish it had a multi color led.

My LED notification light was working and now it isn't. I have the setting "on" but no bueno. Any idea how I get it to turn back on? I hadn't noticed it wasn't working until I read this thread...but I want it back!

weird brightness issue

ok, so try going to 0 percent brightness in a dark room and start like moving around the menus, or using Tapatalk.. do you notice it randomly gets more dim, or more bright, on its own correlating to how much stuff is on the screen? like, I was in the touch buttons display menu and as I moved up and down I noticed sometimes it's brighter, and sometimes it's darker. I think the dna kind of did this too but not as harshly as this.
it's not on auto brightness. I'm on 0, but i think I've noticed this at other levels as well. yeah confirmed i notice it ever so slightly on 40 percent. hard to notice since it's brighter, have to look close. easiest to see on 0.
care to give it a try and let me know?
Sent from my VS980 4G using Tapatalk 4

it seems like it gets brighter when there's more white on the screen. when there's more gray or darker colors, it gets dimmer. seems to do it consistently on Tapatalk when going from like a thread full of white background and then going back to my subscribed which is only like 3 things, so 3 little white backgrounds and the rest is gray.. so it's dimmer there.
Sent from my VS980 4G using Tapatalk 4

and when I pull the keyboard up to reply, I'm using a gray keyboard... so it gets dim bc the screen has more dark color on it.. when I drop it down, it's gone and the screen has more white so it's brighter haha
Sent from my VS980 4G using Tapatalk 4

I haven't noticed any dimness or brightness. I have noticed a flickering of sorts on my call icon and home screen wallpaper. Maybe I'm going nuts or maybe its my eyes...doesn't bother me if its happening. Interesting though.
Sent from my VS980 4G using Tapatalk 2

Maybe it has to do with that graphic ram thats on the display. They said its suppose to save battery. Honestly i thought ive seen this happening on a couple of review videos.

oh yeah? I'm wondering the same. at 0 brightness my dna would change brightness levels around and I noticed it often.. wasn't as hard of a change as the g2 though but perhaps you're correct with the gram!

It's called dynamic contrast and is present in all modern TVs and smartphones
Your TV set is probably CRT, hah?

I would think the constant change in brightness would mean sensors are constantly running and chewing up battery. But then again, I have no idea what I'm talking about

Lol u sound like me, then again i have no idea what im talking about. Yeah i was just guessing on the graphic ram. But i coulda swore on one of the vids i saw the phone was really bright and then it changed and was noticeably dimmer, let me see if i can find it, could have been auto brightness but in the same lighted area it was a huge change if it was. Do u have auto brightness on?

Mine almost flickers if I have auto brightness on,its very subtle but it's there

btw, there was a secret menu for the att version where you could turn off the dimming when the phone got hot. if we could get that menu maybe we could turn that

I'm not sure if it's the same thing as dynamic contrast, but it also sounds similar to some content-aware brightness settings included in some ROMs.

Does auto brightness even work on this phone? I will pull down the notification shade, uncheck auto brightness, put the brightness all the way down, check the auto brightness box and it does absolutely nothing. Anyone else notice this?
Upon further review, if I go to settings and display settings and check the box from there, it seems to work. Maybe it's just broken in the pulldown notification shade?

Yes I felt the same. There is absolutely no change i noticed when i set the auto brightness. I just set it to 30% manually. Not sure if there is a issue with the sensor or just the software..

Default Note 4 notification LED colors?

Seems a bit random to me.
Or very strange (for instance: red color for charging; orange would be better in this case).

I've never understood their color selection, that is why I don't pay attention to what samsung wants for their LED lights.

Good point. Thanks!
Sent from my SM-N910C using Tapatalk

Here is a list of the default colors:
Blue:
Pulses in multi-tone blue while the device is turning on or off.
Blinks blue for a missed call, message or other notification.
Blinks blue when you are recording a voice.
Red:
Glows red when the device is connected to a charger and is charging.
Blinks red when the device is connected to a charger but there is a problem with charging.
Blinks red when the battery is low.
Green:
Glows green when the device is connected to a charger and the battery is fully charged.
I hope this helps

Thanks!!!!

Well.. I installed good old Lightflow and everything's ok now (all email blue, all messaging green, missed calls and low battery red, charging orange).
Too bad Samsung uses strange colors and doesn't allow to change them. I was not a fan of lightflow as it uses battery. Maybe things have changed...
