NoLed apk

I installed the apk NoLed from GooglePlay (https://play.google.com/store/apps/...lt#?t=W251bGwsMSwxLDEsImNvbS5sZWQubm90aWZ5Il0.) and i think it is a fantastic apk as we don´t have a regular notification led as others phones.

How does this work exactly does it prevent your phone from going to sleep? What about the Lock screen? Do you have to remove the lock screen to see this?

You have lots of options to configure the apk, when i receive email (gmail) my phone vibrate, make a sound and the screen blinks an small mail icon, all black, just the icon. You can set how long it will blink, can also ajust the proximity sensor to not show the icon when the phone is in you pocket, and so on.
Too much to tell, install and try.

Seems good!
Thanks

The app is quite good, very customizable, but it drains too much battery. Energy saving options are not enough.
Sadly uninstalled.

Are you referring to with even no notifications active? Or with notifications active?
For me, it doesn't seem to bad, though overall batter drain is like 10% over 10 hours, sleeping with nothing else active.

Can't say.. if i get a text, or just a whatsapp notification or anything else, my battery is drained when i take it back. I don't say that battery is halved, but it is still a remarkable loss.

This is why we need BLN. BLN should use a lot less juice as it is only a small LED and not a big screen. Hopefully someone will modify the ICS kernel and we will get it.

From what you said, i'm assuming you totally has no idea how (AM)OLED screens works, so let me give you a fast walktrough.
On most mobile phones you can see TFT-LCD based screens. These screens uses a background (white) light trough the entire screen surface, this light is first polarized then secondly filtered. This filter is controlled by the electronic, witch results how it blocks or let's trough the way of the background light, resulting the picture what you see on the screen.
However the LED screens, including OLED and AMOLED screen are rather different from the above.
Each pixel on the screen is one tiny independent light source, aka. a Light Emitting Diode.
When the question comes to power consumption, from the above you can see that the TFT-LCD has a relative constant power consumption, because the backlight always has to be on, even if the entire screen shows black.
As for LED displays, only those areas uses power, witch actually emits light, in other words: the pixel/screen area is else then full black.
This is the reason why "use as much black as possible" is mostly suggested for this kind of screen, because if the less leds emitting light, the less the power consumption are.
for further informations please read:
hxxp://en.wikipedia.org/wiki/TFT-LCD
hxxp://en.wikipedia.org/wiki/LED_display
hxxp://en.wikipedia.org/wiki/AMOLED

this is a must have... if u don't have an led and amoled and from what iv'e seen it isnt a battery hog...

I think the BLN pro app would be able to achieve the blinking. You have to buy it though.

Control the LED notification light!

[APP][ROOT][1.6-4.0] ButtonLED​
EDIT: I figured out that we can actually control the LED notification light with this app now. Instead of using the file for the capacitive buttons, just substitute it for one of the LED files.
Green - /sys/devices/platform/msm_ssbi.0/pm8921-core/pm8xxx-led/leds/led:green/brightness
Red - /sys/devices/platform/msm_ssbi.0/pm8921-core/pm8xxx-led/leds/led:red/brightness
Remember to also enable it in Accessibility! It still doesn't work well for any time less than 1 second, but I don't feel like that's a huge deal.
If you want to use the button LED, you can still use that file as well.
Since the OG's notification light (or frequency) is shameful to say the least, I just discovered this app today and it's sooooo handy for our phones even though it was meant for phones with no LED at all. Basically, it uses the capacitive buttons as a notification light.
Download the HDPI version and install it.
When you first open it, you have to tell it where the button backlight file is since it's different on every phone. Ours is located at /sys/devices/platform/msm_ssbi.0/pm8921-core/pm8xxx-led/leds/button-backlight/brightness.
Lastly, scroll down in the main menu to where it says "Enable ButtonLED in accessibility" and click on it. It'll take you to the system accessibility settings where you just have to toggle it on.
It took me a little while of playing with the settings to get it working how I wanted, and you can do the same. I have noticed a few issues here and there, but overall it works pretty great. One thing I found was that if you try to set the LED on time to anything less than 1 second, it just does a real quick flash, regardless of what length you chose. Personally, I like 1 second on, 1 second off.

Thanks for posting. :good:
Have you noticed any change in battery life? Reading the developer's posts, when the notification lights are active the phone doesn't sleep.

No difference so far, but I don't think that I've had a notification that I haven't seen and cleared within five minutes. I'd be interested to see what the drain is if it goes unmonitored for a couple of hours.

I can't even get this app to let me change where the led is located. How did you get it to work?
Edit: never mind I simply had to update my busy box version
BTW: I love you for finding this app

LOL, nevermind, nice find!

Not with this app unfortunately. You can either tell it to use the green color or the "red" (orange) color for the LED and that's it.

Works on stock kernel?
Is this supposed to work with stock ZVC kernel?
Test works, and the logs show that ButtonLED detects and processes my notifications, but it won't light the led.
I tried everything, what he says here too:

But terminal gave me an error creating the path.
does that means it's not supported?

[Q] Charging indicator

Is there a way to disable the charging indicator light? It is BLINDING in the dark. The green is a lot worse than the orange too. I know you can change when the light is enabled for notifications like mail/calendar/etc, but I can't find a setting for the charging.
I've got a status bar and a battery widget to see if it's charging. I don't need an LED that blinds me.

I don't know what to tell you, but if that light blinds you, you must have the night vision of a cat. I can't imagine driving down the road at night with your eyes. On that note, good luck to you.

Haha I had an EVO I think it was at one point that was the same way. I have great night vision...and I don't eat *that* many carrots, so I'm not sure. I'm not usually overly sensitive, but I swear that little pin sized light is ridiculous bright.

You're correct, that light is extremely bright, especially as green. I put my phone on the charger last night, and it finished charging while I was laying in bed but not asleep, and when the green came on, it was like night turned into day. The ceiling lit up like a flashlight was aimed at it. When I get a notification and don't feel/hear the vibrate/noise, the light is quite capable of letting me know I get one.

I just submitted a "support" e-mail to HTC and I'm sure they'll say that you can't disable it because people need to know if their phone/charger aren't working. Yeah, that's what the notification bar and widgets are for if you want them. I had to root an EVO to disable the light on that one too, which is entirely lame. I mentioned that the e911 GPS indicator is both unnessary and annoying as well. This is the kind of stuff that drives me to root a phone (not that I can unlock it at the moment because I didnt' get my phone before they locked down the htc dev site), but once there's a root option for me and if I can configure these...I'll do it for that sole purpose.
Ugh.

Ok, so their response from support was to use "Light Manager" which doesn't work (at least non-rooted) as far as I can tell.
Response from them:
I totally understand where you are coming from on this, as I know how important is to have a phone that fully meets your needs.
In this case, you can use a 3rd party application, which will disable this feature from your device. You can check them at google play store.
https://play.google.com/store/search?q=light manager
I recommend you verify other user’s comments and rating, that way you choose the best option for your requirement. Please keep in mind that HTC does not support or warranty 3rd party hardware or software and its usage is at your discretion.
I apologize for any inconveniences you may have experience, our main goal is to provide you with the greatest devices and an spectacular HTC experience. I will address your suggestions to the proper department; I can not assure you it will be implemented however we take them to account and appreciate the time you took to contact us.
I look forward to assist you further in case it is needed.

Can you double tap the screen to wake?

Just wondering if when laying on desk do you have to lift the phone up every time to check messages.
Also how are the led notifications.

Double tap not yet.
LED notifications you can turn on (Settings -> Notifications -> Gear Icon -> LED option is there).
The LED is in the top speaker grill on the far left. I noticed this glow blue when new messages come in.

LED works great, I miss having it. No double tap of the screen or Raise-to-Wake which sucks a bit. However with the LED I don't miss it as much as I thought I would.

There are two LEDs. One is in the top speaker grill on the far left. I noticed this glow blue when new messages come in. Additionally, there another LED to the left of this on the bezel area that glows white when I get other notifications that aren't messages. I'm unsure if there are other colors currently.

Have you enabled the LED notifications in settings? It is disabled by default. You need to manually turn it on.

Double tap to wake is available with a custom kernel

I read from an extremely ( and I cannot over emphasize the word 'extremely' enough . . . ) reliable source that 'sweep to wake' is much more responsive and bug free.
.
I can remember tapping away on my nexus 6 and saying 'what the heck', . . . . and 'come on' . . . .
and then I went to the sweep thing and it was rock solid.
truth.

Maybe it'll be bundled in the next security update, hopefully early November

It's time we start looking into the Heart Rate Sensor Light as LED Notification

Painfully, Samsung have removed the notification LED hardware, a $0.20 savings for the company. Now it's time we should look into the Heart Rate Sensor's LED lights as notification LED. At least, we will get something on device, though on the back.
I believe it may be possible if we can acces to the SDK. Only two things, if we can pulse that LED alone and how much powet utilization may happen. Lets see if someone can find this up. I will also start looking at the Samsung HRS SDK. I know we have more skilled devs. Lets figure it out guys.

You can already use the camera hole punch...
https://play.google.com/store/apps/details?id=com.used.aoe

I agree with you. I know that Always on Edge is available for Notch notification. But with this on, we risk AMOLED burn-in. Also, this is not a hardware. Since the heart rate sensor have an LED, I think that will also be useful for a lot of us. Lets see if we can figure something out. Also, we will have the option to use, whichever is more helpful for us.

I read somewhere in the forum, that Samsung is working on using the camera hole punch as LED notification, similar to how it behaves when you switch to front camera, also it was written by a Samsung Ambassador on the Samsung Forums.

TBF Turning your phone on risks burn in. Having on screen buttons risks burn in. Using your phone outside risks burn in. Just live a little and don't worry about something like that as much. Just my opinion.

There's an option (when you check "when a notification comes" and "and screen is off" or "always") to show it 8 second every 30 second.
BTW, it's not really reliable this app, sometime works, sometime not. Let's hope samsung will implement a similar system setting.

We like strobe lights from a distance

In the latest ASCA update, the blue light in the heart rate sensor blinks when power sharing is enabled. So, there are plenty of chances we could enable the same. Although I am pretty much ok with the current AOE implementation.
