(Q) LED notifications - Xperia Arc Q&A, Help & Troubleshooting

Hey guys,
Despite the poor placement of the LED light on the Arc, is there any build.prop tweaks or apps ( compatible with ICS preferebly) that make the LED light work/persist for notifications? I have a feeling that it does work but then turns off as soon as the screen turns on but that is rather pointless ( not sure about this)
Thank you guys.

That's how Google intend it to be since 2.1. Unfortunately I haven't seen or come up with any solutions yet..

hope this helps

[Q] Will Google be 'fixing' the LED notification light any time soon?

I'm glad that a Samsung high-end international Android smartphone finally has a good RGB notification LED, but the way it's been implemented in the Galaxy Nexus is pretty damn poor.
1) The blink rate is terrible. On my Motorola Milestone, I'd come back into the room and take a quick look at my phone to see if the LED is blinking. With the Nexus, I have to bloody stare at it for 10 seconds.
2) No customisation options. What's the point in having a white light for both my text messages and emails? At least Whatsapp lets me choose different colours I suppose...
Now, I know there are applications out there that can provide remedy to these issues, but this is another thing that I don't want to rely on third parties for...
So, my question is this: Will Google be fixing the Galaxy Nexus' notification LED, or will I have to resort to using Lightflow?
Its not broken. You're comparing it to a different phone that had an oem overlay. It's there for developers to utilize for app features. Now you can edit the code to make the blink rate faster just like the rom I'm running (bamf wookie) has that edited. But google will probably not be doing anything further than the way it has already been implemented.
good day.

I know you said you don't want to go 3rd party, but I think LightFlow might be one of your few options. I just set it up today, and can tell you that the "Very Fast" setting on LightFlow makes the LED blink every second. So far I am very impressed with the customization options of LightFlow and might even purchase the full version soon.

Compared to the hardware of the last Nexus device, the Nexus S, with no notification light, this is definitely an improvement.
It would seem logical to implement controls for the LED notification features in the Settings panel. From a technical stand point, the only downsides I can see to adding support for this feature into AOSP would be not all devices will support it.
As far as I've seen, and I could be wrong, the majority of LED control is performed through the specific sysfs structure setup by the kernel. Controlling the LED through this route require root access so if the third party apps control the LED w/o root access, I might be a bit behind the curve.
If you were interested in moving the ball along, all of the ICS source code is public being part of AOSP. Theoritically you could work on implementing controls for it in the Settings.apk AOSP file and send your changes to Google requesting they add it to their official AOSP repo.
In the end, I do agree. Adding controls for a LED notification light, when a notification LED is provided in the hardware, to AOSP shouldn't be *that* difficult.
Apparently this hasn't been a priority yet but hopefully now that the official Google device has a notification LED, they'll move in the direction of adding at least some simple stock controls for it.
Is there an official site for this aosp code? I goggled it but didn't knife which link is the official download site. Running GNex Sprint.
Sup Milestone buddy .
I've long since decided that Light Flow is literally the only way you can get the gsexy's LED to function the same way it did on the Droid1/Milestone. You should try it or at least try Galaxy Nexus LED (on Play, it's free) first.
install lightflow
I agree with OP. I know it's all about finding the workaround, but workaround's and third party fixes are not always the satisfactory answer. It would be nice to have out-of-the-box notification light controls.

[Q] DHD Flashlight as a reading light.

Hey peeps!
Question First: Has anyone else found a LED flashlight app that works well on the DHD or Inspire that can dim the LED right down?
I want to use the LED on the back as a reading light so I don't have to drain the battery by using the screen but its simply too bright.
I am running an Inspire 4G on Revo HD 6.3.1. The stock flashlight app works well with the 3 levels avaliable and I don't want to kill the LEDs by over running them.
There are tonnes of flashlight apps out there, some using the led and some not. The ones I have researched either don't have a brightness adjustment on the LED or attempt to burn a hole in a sheet of paper.
The only app that I have found which relates to this is call "Reading Light" and is just an adjustable brightness grey screen.
If this has been discussed before please let me know and i'll request this thread be closed. I couldn't find anything regarding this aspect of the topic.
Regards,
Akida
I don't think this has come up before. Its a good request. I'd be interested in something like this.
Bump
Bump for confirmation of possibility please!
Btw .. how often am I allowed to bump? I couldn't find it in the forum rules.
CM 7.1 has a application called Torch which has two light levels. The dim one seems like it would be perfect for reading (it only uses 1 of the 2 flash LEDs). The bright level is insanely bright (much brighter than the Sense flashlight app).
There is an app on the market called Torch, but I don't think its the same one that comes with CM 7.1.

Hey that sounds like its worth a shot. Has anyone extracted the app from CM 7.1? I'm going to ask them for permission anyway.
Thanks for the info.

Everyone knowz ...nothin new
Sent from my GT-I9300 using xda app-developers app
What colours has everyone got working?
For a while, installing it stopped all notification lights. I only wanted it for sleep settings. I changed some colours today (red and green) but then even what was left as blue stopped working.
Test only shows green too.
It just seems to be unreliable for now. I wish I could get tasker to turn off notifications.
On my phone (I9300) it worked, but not perfectly. There were some audio outputs activated. Like someone is commenting me, while I'm doing pinch out on the touchwiz launcher. Idk why, but that f*cked me totally up, so I had to delete this app -.-
hopefully it was a bug, but it was really annoying.
EDIT: A glitch inside this app activated partially the talkback feature, to be concrete.
HTC Desire S!
I guess its not working on HTC Desire S can anyone confirm I tried but nothing happened no change in light color!
I made a video for the Samsung Galaxy S3 LED indicator and the app Light Flow Lite!

Notification LED Replacement Idea / Request / Question

So the notification LED was removed for god knows why for the first Nexus / Pixel device that I have owned.
I know there is some cool stuff that can be done with the OLED screen but I don't want to have to reach for my phone to check notifications and I really do not like the always on feature.
I tried Pixel Pulse and got the paid version at least someone is trying, was not my cup of tea.
I was looking for a way to add circle notifications to the bottom of the phone like the Nexus 4 used to have. Video for reference (https://www.youtube.com/watch?v=TEIOMPZUMmg)
Having this feature back again would be great. Anyone know of any apps that might be able to pull this off?

Question Notification light

So I don't know if it's on here or not but I came from a Samsung phone and so anytime a notification will go off it would flash a green light does the OnePlus 9 pro have that same feature or some type of light that could flash when a notification is on the device? Perhaps maybe there's some type of a magisk module that can utilize the camera ring around it to flash when there's a notification if it helps I am on a custom ROM. So I'm not sure if stock has it. Thanks.
On recent OnePlus phones, you'll find a function called Horizon Light (it basically lights the screen's borders when a notification is received), that is used for similar purposes, but there isn't a notification LED in the hardware.
I'm not sure if it is a function that is still in your custom ROM, but it is a stock ROM function.
Yeh, only aware of built-in horizon light , but it doesn't flash long enough to catch it....
Geez, how I miss the LED notification lights that older phones had.
Especially the ones that were multi-color so you could assign a different color for different notification types.

Technically, it wouldn't be impossible to recreate it with an app dedicated to modify the always on display features.
As AMOLED screens are basically tiny LEDs side by side, we could imagine a way to light or pulse specific ones to remplace the "missing" one. But it would be a trade-off, as those selected LEDs would be functioning and aging surely more quickly than the others.
There are a few apps out there that will use the AOD to create the appearance of a notification light or even continually flash the Horizon light bars and other custom lighting options however all 3 I've tried were glitchy and obviously drained the battery since it's using AOD to accomplish the notification light. Maybe if you're already used to AOD battery drain it wouldn't be so noticeable but I don't use AOD normally so the difference was very noticeable to me.

Yes, it's also a thing to consider, but I don't think the memory and power usage for only a black screen and a color dot would be that energy consuming. Did you notice a change that big when you gave a try to those apps?
look for notifybuddy on the playstore. works fine on my OP9Pro.
I didn't realize how much i relied on the notification light until it was gone. The AOD fits my needs, tho. Posted settings on another thread awhile back: https://forum.xda-developers.com/t/horizon-light.4371367/#post-86085187
I may give notifybuddy a try, too
Would recommend this app. I've been using it on my oneplus devices last couple of year. There are a lot customizations too.
LED Blinker Notifications
i REALLY missed my notification LED (the last phone I had that had it was my old blackberry priv) then I got a smart watch and I don't care so much anymore
