notification light?

i saw a white light on the bottom corner on my xoom;s screen. is it for notifications?

Depends on how you hold it. The notification light is a white (supposed to be tri-color) line next to the Verizon logo.

My light pulses White every 2 seconds or so when I get an IM on Gmail Talk. Edit: Only when the screens off, btw.

Here are the steps I took to learn this information:
1) Read the labels on the film taped across the front of the Xoom's screen as it came from the box, where it's pointing to NOTIFICATION LED
2) Read the user manual
3) Use my common knowledge and history of using mobile, connected devices to understand that a blinking light means something new has happened or arrived on the device.
4) Post a question on the forum
I think this is my first post, but I gladly use it to point out how newbish you are to have to ask this question on the internet.

Thanks for being a jerk. You may also want to make sure that you have notifications turned on whatever apps you're using.

Top light to the left of the camera
There's another light, just to the left of the front-facing camera. Does anybody know what it does?
The light to the camera's right glows when the camera's on. But the light to the left doesn't seem to do anything yet. (And it's not listed in the manuals nor on the plastic pull-off screen protector.)
Judging from the iFixIt take-apart photos, I'm guessing it will light up when the Xoom is running 4G.
Anybody else know more?

WOW thanks for your reply!
1. the label was taken off by the verizon employee when it was activated so i don't know that there was a sign that pointed to it.
2. the user manual did not specify where the notification light for apps are only for the charging light.
3. i know it is used to notify if something arrived but like i said it DOESN'T light when i get IMs even when the screen is off.
4. it is posted on the forum!
thanks, but i don't need your sarcastic answers.

I'm fairly sure what you are referring to is a light sensor, for automatic brightness adjustments.

I actually had sorta the opposite problem in that I had the notification light going for seemingly no reason. Checked all apps and no notifications on bottom bar. Reboot solved but made me wonder what was up.

If you can't see the notification light it most likely has to do with your screen brightness. I thought mine was broken when it was so faint, so i cranked up the brightness and sent myself a test e-mail. When the screen was off the notification light pulsed incredibly bright, i turned it down repeated the test, and the notification light was really faint. Hopefully they can change that to where it's always bright no matter what the brightness of your screen is set at.

I assumed the notification light is only when the screen is off. Why do you need it when the screen is on? You can see all notifications in the lower right.

Also, lets not forget the notification light on the BOTTOM center of the tablet in landscape.
It only comes on if the device is OFF... its a battery charge light. Its 2 or 3 colors that change depending on the charge level.

What I'm saying is that the brightness of the notification light when your screen is off depends on the brightness your Xoom is set to. If you have your screen at 100 percent when its off the notification light will be very bright. However I had my screen quite dim and when it was off ans I received a notification, the light was almost nonexistent. You can test it for yourself. Its something that is hopefully fixed so that the notification light brightness is independent of the brightness your Xoom is set to.

Oh, I am sorry I misunderstood. I tested it at lowest brightness setting and the notification light is just as bright as full brightness for me.

Yeah, mine works now too, weird, I rebooted it so there must have been something wonky going on, but everything works now.

Green LED light staying on... can't figure out why

I (of course) do not have root, but I am running light flow. It seems to be working fine, the LEDs that should go on are working and in the proper colors.
I have unchecked all the LED notifications under settings.
However, when I turn my phone off, the green LED light goes on immediately. It is not plugged in, and it's down to around 92% battery or so.
I even tried disabling all charging/battery related LEDs but still the green LED is on.
Anyone else having this? Any thoughts?

Light Flow is known to cause problems on the S3.

And I was wanting to download and use that.

Yes, I see after further testing that uninstalling light flow fixes the issue. Dangit, it appears light flow is far and away the best LED app. I put a note in feedback about it, hopefully the dev will be able to solve it. I'll try it again once we have root for the US version.
Any know if the light flow creator is working on this?

It's listed in the known issues on the developer's site, so I assume they are working on it:
hxxp://www.folioflow.com/ff/page/website/lightflow/pageId/1931

it has something to do with interactions with the built in notifications.. if you disable them then light flo doesnt work.. if you turn them on then whenever the phone goes to sleep a green light comes on.. bummer

i used the LED color tester app and all the LEDs colors are off from what the previous commands were, i guess... so its going to be a while until the led programs work properly

Question regarding notifications and the display

On previous phones, when I got a notification, say a text message, the screen would light up and I could tell I had to check my phone. On my N4, when I get a text the phone only vibrates and the screen doesn't light up. Is there a way to have it light up? I tried looking through all the settings but couldn't find anything, and I find it rather odd LG would set their phone up like this.
Also- is there a way so that the pulse notification light goes off more frequently? right now I have to wait about 10 seconds for the next pulse light to go off, making the notification LED rather useless if i miss it the first time.
Thanks.

There's custom ROMs such as CarbonROM, Xylon, ParanoidAndroid, or XenonHD and so many others) that let you configure the colour, blink rate, and application-specificity of your LED indicator. You can also look at Liteflow to customize your LED notification if you'd rather not go to custom ROMs

This. But if you are rooted and having a custom ROM, they integrate it by default. But if it's really waking up the device you want, you might want to try an app called SMS WakeUp. (You can get it from the Play Store)

Front and rear LED's? Are they both RGB/full color?

Does the front LED allow you to choose any color (like the Nexus 4, Galaxy Nexus, etc)?
Does the rear LED allow this too?
Do apps like Light Flow allow you to properly set different colors for different apps? Can you use both front AND rear LED's? Thanks!

I can only speak for stock:
You cannot choose the colors for each event, but you can choose which event you want to blink. The colors for each are preset, most are green.
The rear seems to be one color, but only works for:
Incoming Call
Alarm
Ongoing Call
I believe Light Manager (nonRoot) allows you to change the colors to anything you want (on the front). The back I believe is only hyper white. It has a very nice looking pulse to it. I believe people trying light flow could not get the app to detect the rear LED. Someone else can confirm.

using light flow i got the rear led to light up but it does not flash like the front so like when you get a message the front led is flashing and the rear led stays lit up and its only color is the hyper white

Front is full RGB color. Back is just white. You cannot globally change the color for specific notification types. You can however change the color for notifications from specific contacts to colors like purple, yellow and pink (and more). It boggles my mind though that you can't change the color globally. Hopefully a custom ROM will add that.

Some have reported inconsistent results with Lightflow. Also, I'm a battery nut and hate having extra apps running for such specific things like controlling the LED, not to mention a persistent Lightflow notification when it's running gets under my skin. Yeah I've got a bit of OCD when it comes to my gadgets heh.

Light Manager is working 100% accurate for me. And I'm not even rooted yet.

Can anyone confirm that the rear LED flashes only once then stops? I couldn't find a setting to make it flash more than once.

This is working perfectly for me as well. you have to disable the built in notifications in settings but after that it works like a charm. No constant notification and no battery hog

For the time being looks like Light Manager is the answer.
For a few versions now the custom ROMs for my Gnex have had their own LED notification setup built in. You can set any color for any installed app, and it was always ultra reliable. So once the development really kicks in for the G2, I dont think we'll need any external app for it anymore.

This is all good info. I don't like stock SMS apps because I have more options with third party like GoSMS but sadly I couldn't get it to access the notification light. Very weird considering every other phone I've owned had no issues there.

How you set the Light Flow to use the Rear LED in way you describe?
Front LED works perfect on my LG G2, but i can't set the rear to light up using Light Flow.

This; I'd like to twiddle the rear LED too, although I know it's limited.
Also, has anyone gotten the Camera Flash to work? So far I haven't gotten it to work, but the front LED is working fine.

Can anyone please tell me how to configure rear LED in Lightflow ?
I am not saying step by step but please tell briefly. Thanks

LED Notifications

For some reason the notification LED doesn't function on my XL2. I installed LED Blinker Pro and it works like a charm. Just thought I would share incase anyone else is having this issue.

Settings, apps and notifications, notifications, blink light. It's off by default.
Now go get lightflow and go nuts.

I did that and it still didn't work. That app solved the problem though.

Have you used light manager? And if so which do you like better. Im using Light Manager but that app you showed looks more polished.
Also have you noticed this time around the phone has trouble making some colors. Like yellow looks kinda yellow/green and white is kinda blue/white

Light Flow works. But it seems that the built-in notification light triggers first overriding Light Flow. For example, if I get a text message (fast blue blinking light set in Light Flow), I get the slow, white stock notification. If I unlock and then immediately re-lock the phone Light Flow kicks in with the set blink/color settings. I've tried to disable the stock light notification, but if I do Light Flow won't work at all.

Light Flow didn't work well for me.

So is this just a software issue that could be addressed by Google in the future?

My 6p was the same way when I first got it.... But once they built in led notification into the settings of the roms I then got more cookies and very crisp distinct colors too..... Im sure the custom roms and kernel will fix this and the OLED panel color issues

Light Flow works perfectly for me.
Enable the light in system settings.
Disable it when there is an option in specific apps.
Make sure it has the right permissions.

I installed the New Pixel 2 XL Launcher on my OG Pixel XL. My light stopped after installing, so I had to go to the launcher settings (long press blank area on home screen, Home settings, Notification Dots, Blink Light) and turn on the light in there to get it going again.

Yep, that's how you get the LED to work. It's really wonky and idk why they buried the setting in that spot.
