No notification LED on my Incredible

I recently got a used Incredible. Everything seemed good on it, except the optical trackpad wasn't working. It'd work for button presses, but not navigation. After acquiring a screwdriver set ($6.15 total at Lowe's) that had T6, and watching a couple of videos on the Incredible teardown, I opened it up, re-seated the ribbon cable for the optical trackpad (it was slightly askew on one side), and it works perfectly now.
Well, close to perfectly. The notification LED doesn't seem to do anything at all. Never, not when charging, not when I have notifications, period.
I've not been able to find anything online specifically dealing with the notification LED. Is this something that might also just have a loose or improperly replaced cable, and I could conceivably fix easily? Or is it soldered to the mainboard, and if it's dead, it's dead?

LED notification also depends on the ROM.

Theres an application called "Light Flow" that lets you play with the LED settings and also as stated above there could be a software issue.
Also by some random chance the previous owner may have blacked it out. I've been annoyed with some leds before so I've cracked things open and sharpied them to death.

LED notification is pretty useless anyway. It has never once let me know anything that I didn't know before. 1button to power screen on to see exactly if you have a missed call/text/low battery/if your phone is charging/ etc.

I don't miss it too much, I just would prefer for my phone to be -fully- functional.
When I had my Eris previously to this, I did find it handy to be able to glance at the phone from across the room and see if it was blinking. That's really my only "useful" loss.

Well, it's not doing anything on Any ROM. Stock, any Sense based ones, AOSP ones, nor even when charging.

If you're using FRX7.1 it already does it.
Mine flashes green when I get a text or voice mail and red (orange?) when I get an email.

Indeed, to the first part. FRX07.1 now has userland control the LED's instead of the sleep state.
So this is what I've noticed thus far. When plugged in, the LED will be orange for charging below 90%, and green when above 90. The notification I believe trumps it tho, and AFAIK the only notification from email/text/etc should be green blink. The only time I've seen orange blink is when the battery is critically low! Pretty sure that's all the feedback it provides, let me know if you guys see something different.

oh! until now I have knew that why the LED turn on green while I 'm connecting it to PC ( firstly, I don't why and it turn on green only when battery 's full ).
Dear Arrrghhh,
as my idea it turn on orange while it's connecting to PC ( sync or charge a battery if the power less than 100%) until to 100% the led will become Green it notice for user know that battery 's full )
Could you please create more function as same as WM while connecting to PC, I thing it will be longer life of battery
it's : user will have 2 choices ( agree or not agree charge battery while connect to pC)

The LED deosnt work for me only when I charge my phone but not when I get a text

Uhhh... mine definitely blinks green when I get a text. Perhaps I have it backwards and when it's plugged in that notification trumps the other...? Are you using some 3rd party app to handle texts? You get no blink on or off the charger? I don't know why it wouldn't work for you, but does work for (literally) everyone else.
You didn't change anything with FRX07.1? Nothing? Just want to make sure, because if you did something like move to an old rootfs, userland notifications won't work properly.

My experience is just the opposite, charging (solid, orange or green) trumps notification (blinking). That's how it works in WinMo, so it wasn't a surprise to see the same in FRX.

I'm using K9 email which (in theory) lets you set the LED color, but no matter what I use it's always orange.
I do also get blinking orange for critically low battery.

Perhaps that's your problem? Dunno. You'll need to do some legwork if you modified the way the system handles text messages.
I use Google Voice and the stock messaging app for MMS. Both work great, and notify me correctly. As does the built-in GMail app...

If you did remove it from /system/app, just pull the apk out of a fresh system.ext2. Or just throw in a fresh system.ext2 file, you won't lose any data assuming you leave the data.img untouched/intact.

How many LED notification colors are there when using Light Flow?

For those with the Verizon Galaxy Nexus, how many different color notifications are there for the LED when you use Light Flow?

17 colours to choose from on mine, it seems.

But will the phone display all those 17 or only say 4?

The Nexus has a RGB LED so any of the 17 colors can be mixed without a problem.
Why don't you try it by yourself? Lazy?
Despite that I have 19 colors to choose from on my GSM Nexus with Light Flow (paid).

Just a quick warning from my experience with Light Flow lite.
I installed the free version and it worked fine - I think I used 10 different colors and most of the time the worked well (sometimes the light would stay on when the notification was cleared).
However, I was having battery life issues so I uninstalled the application.
This actually GREATLY improved my battery life - but now my led is broken. It will only flash white, and it doesn't work for all events that it did before I used LFL. I've done a factory reset and a battery pull and the led will not go back to green.
I've emailed the developer and hope I'll get some help. It's a little hard for me to understand how this could happen and I hope I can fix it.
Just a word of caution to anyone considering using this app.

I don't think mine has ever flashed green? The stock notification for mail + sms is white, and tweetdeck is yellow... not seen anything else?
I too uninstalled Liteflow, because I found it frequently flashed forever until I rebooted when there were no notifications.

On the Nexus one, CM7 had a slider control for colors. You could create hundreds of different shades.
I think the Galaxy Nexus is the same. At this point we're only limited by software. RootzBoat rom had a LED color control built right into the general settings menu, but only had a few color selections. I used blue and I liked it alot. I don't think it allowed you to change it PER APP, but just the general color for all. Still cool to mess with again.
3rd party programs require to be run in the background as an app or service, but require constant monitoring. Kernel level control is best, but we'll have to wait for CM9 for that.

Ok then - maybe I've lost my mind! I thought I remembered it being green originally but it's entirely possible you're correct. Would make much more sense than to think that an app could 'break' the led functionality.

+1 for jmbillings.
Natively the LED is only flashing only whitish and as to be readable in a couple of threads not even that is working properly at all times.
Never had any issue with Light Flow except a not stopping notification ones a week. Bought it for Whatsapp and I'm still happy. No battery drain at all at no time.

you guys must be getting dozens of notifications in a day.
i've never even seen lightflow pop up under my battery statistics.

I use light flow on my Nexus and it works great!

Same here lightflow works great on my Nexus. And every single color I tried works. If some people are having trouble with the light still flashing even after swiping the notification away, try going into the app itself. It apparently will keep flashing until I actually check the notification out in the app.

Light flow didn't work for me, it would either flash constantly in test mode or do nothing. My LED does flash green for chompSMS but white for everything else.

light flow works 100% for me. Notifications always work and no notification his become 'stuck' when I clear it...

Well maybe it's a native problem that I'm having. It will not notify me now of a missed call or an email. The only time I'm seeing the led blink is when I get a text message.
The developer actually took the time to reply to me and make some recommendations to improve battery life.
I'll give it another try, still having intermittent battery issues but may be more related to location polling than this app.
Thanks again to the folks here who take the time to help out.

Yes, I do.
I don't see it under the native battery stats - it did show up fairly high on the list when I was using battery monitor widget.
Honestly, trying to figure out my battery issues has me suspicious of every app I install...

Works perfectly on my Verizon Nexus as well. The only hiccup is Handcent. If I dismiss the popup window on Handcent, the LED will continue to flash, until I actually go into Handcent and view the message,

I was using it to alert me if bluetooth was on, and that notification would tend to persist after I had turned bluetooth off.

For those having issues clearing the LED notifications, keep in mind just clearing the notification from the drop down won't turn off the LED. It will stay on until the notification is further acknowledged (i.e. the SMS message is 'read' under messages...or email etc).
Also, something I've found helpful is the lightflow debugger widget that comes installed with the app. From there you can clear all notifications as well as see what the last notification was

Technically the phone works well with all 17 colors - but as a male i must say that there are only approx. 8 colors existing in the world...

I think they need to combine the app (LightFlow) with the color selector from AOKP ROM. Its basically the MS Windows/Photoshop color chooser we're all used to: a circle with a slider to the right. The combination of those allows you to choose ANY color in the spectrum. And the LED will display it. (Blood red is my favorite....not as "light up your room" as the default cyan/white)
I did catch the LED lighting up yellow when I had a text that didnt get delivered....not sure if thats the SMS app Im using (GoSMS) or the kernel/ROM but something made it flash different color at different frequency.
Id love LightFlow just for all the apps it responds to....especially Words with Friends.

[APP] Light Flow

the developer has claimed the latest version on the play store is working for rooted phones, but I still am not having the best of success. I thought I'd start a thread and see how others are fairing.
The newest version has some improvement; being able to select different colors for different notifications and actually getting them to go off when you've pulled down the notification bar. however, it doesn't blink for me at all. When i get a text or email the corresponding light is a steady constant light if the screen is asleep. If you wake it up the light either disappears or only lights up very infrequently.
I've read some posts before the latest versions came out that some users had success getting it to work by actually turning Accessibility off. This seems to turn off the entire app for me.
anyone having better luck?

I have had the current version working correctly both on a stock TW rom, and now on CM10. The flashing lights haven't been implemented yet, however he is working on it.
The only thing I had to do on the Samsung TW rom was disable Samsung TTS in the manage apps settings. Once I set it to S3 root mode, everything worked perfectly.
I suggest you follow his blog here:http://www.folioflow.com/ff/page/website/lightflow/pageId/1826

I have done all that including following the developers blog. I have accessibility on, only have the light flow notifications turned on, allowed SU access to light flow app, and have tinkered around with it all weekend but it still isn't working correctly. It works fine when the screen is on, but when the screen is off it gives a solid light.

Its not supposed to blink get, that's why I linked you to his blog.

A blinking light will kill the battery or at least use more juice. Dev did say he is looking into that feature tho
Sent from my SGH-T999 using xda premium

Developer advises blinking uses more battery than solid notification. Go figure.

Since I installed Light Flow, whenever the screen is off the LED glows a faint green. First I disabled Light Flow and the led still glows green. I unchecked it under Accessibility and rebooted, still green. Just had to uninstall and reboot to get it to stop. Anyone else have this issue? Is there a setting I'm missing somewhere?

I had that issue when I restored from an old version of light flow. The newest version that I installed straight from the Play Store works fine.

I believe to get other colors other than green, you need to be rooted and go into the app settings and check "S3 root mode" or whatever its called...
Works perfect for me.
EDIT: I think the updated app (as of today) should work whether your rooted or not.

The update version today also supports blinking in adjustable intervals.

I would agree with that almost fully except it's a pain setting up different notification sounds between e-mail and sms/mms. It's also nice to be able to have it make notifications at intervals from missed calls/sms and the light to go away eventually if you want.
But I do have to say, I'm on CM10 - Paranoid Android ROM(latest build) and light flow is working like a charm for me right now. Looks like the bugs have been worked out for the most part.

Hi guys.. I have an international S3 and since a recent Lightflow update, I regularly get lightflow causing wakelock for hours. even with no outstanding notifications. I've uninstalled, re-installed - same problem.
Happened 3 times this week. reboot fixes it.

Has anyone figured out to get light flow to overwrite the settings for the notification light in settings? It seems like my settings from both are working.

by rooting the op3.. i dont know about the unrooted phone.

For me, even with root and playing around with the LED settings, no luck.. I cant get it working unfortunately. The fancy stock colors the OP3 shows (especially for google+ or tapatalk) are dont even make sense to me.

I'm using this combination as well, and it's working.. sort of. When my screen is off, the notification light constantly cycles through all the available colors, just like when you run the test and have to turn the screen off.. only permanent. Not sure why it's happening, never had this issue w/ any previous devices. I did restore my data from previous install, but I've gone through all the settings and checked/unchecked at some point and it's still happening. Thoughts/

On Oxygen I read also some people that has problem with stock led control.. Then probably there is something buggy on our system..
I didn't try any other led app however.. Did you?

Oh that's good to know, thx for sharing. I haven't tried any other app yet, I just disabled LightFlow for now since the constant cycling has to chew up extra battery when the screen is off. I'm also still on 3.1.3, going to upgrade to 3.1.2 and see if that helps.
