Touch Key Light as Notification Light - Galaxy A3, A5, A7, A8, A9 Q&A, Help & Troubleshoot

Hello,
Since my A300FU doesn't have LED Notification, is there any mod that allow Touch Key Light work as Notifocation light? Because I do remember, long time ago, someone manage to mod i9000 touch key light to become notif light.
So, I believe there is a chane to mod it in our A series phone.
Thank you very much.

Touch Key? Do you mean Capacitive Buttons?
There's an app for that if i am not wrong. I'll drop by after i found it...

I don't know exactly what the name of it, but what I mean is those 'back' and 'recent app' button.

Yes, those are called the Capacitive Keys or Buttons.
It used to be kernel dependent with the BNL stuff, but i've seen a lot of apps do this now.
I found these:
http://www.redmondpie.com/transform...d-device-into-notification-led-with-this-app/
http://geeknizer.com/use-capacitive-buttons-as-notification-led-on-android/
i had no time to test so dont consider this researched yet ...
the lack of LED lights in A series sucks...really short sighted sammy.

This is a kernel feature called BLN. If the kernel does not support it, then no app could activate it or use it... A500FU stock kernel does not support BLN

yup, i may stand corrected there, but i havent seen BLN stuff for ages...in fact, i've seen it last in S2 forums.
btw, i remember BLN being a battery hog...

Or... instead of BLN, you could use camera LED flash when receiving calls, messages, or notifications...

NoLed from playstore is almost as good as having LED for our AMOLED devices .

So, I believe, what we need right now is kernel developer, because I think we can get the kernel source of A300FU from here: http://opensource.samsung.com/reception/receptionSub.do?method=sub&sub=F&searchValue=a300fu.
Right?

You are kind of wrong. Its whole different in AMOLED displays than LED displays.
On AMOLED the whole screen doesn't turn on. Only those pixels that are being used.
And I can assure you, absolutely no extra battery drainage what so ever occurs.

[Q] [REQ] Enable a led on the NS? is there one to enable?

Is there a led that a dev can eventually get to work as a notification led? Or is there simply no led built into the phone that will work. This is a very crappy issue for us NS owners that came from the N1, I miss my trackball lighting up from across the room and knowing wether or not it was a txt or an email etc..
Will the NS ever have this? Or is it simply not going to happen?

A) Wrong section.
B) Answered in the stickied FAQ in the right section:
unremarked said:
Q: There's no LED Indicator? What are those two circles next to the speaker?
Correct, like all Samsung devices(minus the Epic 4G on Sprint) thus far, there is no LED indicator light. There are apps, such as NoLED, on the marketplace which work great on the Nexus S and provide more or less the same functionality. Those two circles are the Proximity Sensor and Ambient Light sensor.

Not really the wrong forum if it were something that could be developed. It would have been a request for something to be developed. Regardless, I guess we are just stuck without an led light. NO LED blows compared to the trackball on the N1

There's literally nothing to be developed, mate. There is physically no LED light in this phone unless you wanted to open her up and install one yourself.

Splitting hairs there, bro.
And yes, I'm sure the.. er.. I'm blanking on the name of the app that will use the buttons as notifications will come around once a custom kernel has been developed to support it.
not sure why we need ANOTHER thread about the LED (or lack of). do a SEARCH!
Closed, as this is answered in the FAQ.

Why wouldn't you want useful things?
Out of curiosity, which tablets do have notification LEDs? I've tried searching but it's come up vague.
i've yet to see any tablet with an LED.
It's not needed as much on a tablet as on the phone with missed calls and texts.
NoLED should suffice just fine. And NoLED combats burn-in by having an option to move the notification around so it's never using the same pixel for long.
ive had noled on all s1 and s2 and s3 and i have never had any problems with it and now they have themes!!

NoLED is really only for OLED screens, on an IPS it will run your battery bone dry in double time
Notification lights for things like Gmail, Facebook, Twitter
My HP Touchpad has an LED...
Idea, is it not possible to make a costum ROM with a function, "use screen as notification LED"?
I do not mind that there is no LED. I have a U20I thats runs so slow, that any replacement for android gaming is good for me .
My current tablet has capacitive keys and I use backlight notifications, so not having BLN will take a little getting used to.

NoLED has an option to not turn the screen on when the proximity sensor is "close", so you can just keep the tablet face down when it's not on the charger.

You don't need a custom ROM. NoLED will do what you want.

[MOD] Torch boost! Full LED power when using your Z1 as a light source!

Hello guise,
This time I'll share with you something that @RyokoN found out. Please thank him here. I just made proper changes to the file he mentioned.
Someday I was killed by my friend N5 torch. It was so bright. Now I decided that I want my torch to be actually useful, just like his torch is. (we were trying to see details in a dark place to fix the window).
It may break your LED if you leave it on for some time. I'm not responsible for any damage. It actually made my back around the LED a bit warm after a few seconds in the extreme version!
Please be aware that it's not safe to test it on devices that are older than Xperia Z as LED's may vary hardware-side.
Anyway, enjoy
Extreme version - just torch
Medium version - just torch
Medium version - torch, camera, flash, notification LED <------------ RECOMMENDED!
Extreme version - torch, camera, flash, notification LED
Revert to stock Z1 torch
It's based on Z1 .108 firmware (4.4.4), but it WILL work on 4.3 roms. Can't say about older android versions - you tell me!
Please test and let me know how it went
It's significantly brighter now. At first it barely gave any light and now it's even brighter then the light in my room on a small distance, lol.
Confirmed working on:
Z 4.4.4
ZR
Z1 Compact
Z1s
Z1 4.3 4.4
Z2 4.4
Z3 4.4
That's what I'm talking about! FINALLY a flashlight that I can use! It works great!
Wow! Tks to your mod, I'm finally throw my flashlight out in the garbage because now it's brighter that that old flashlight.....
Have you checked if the led can endure the increased amount of current?
i dont want my led to be damaged permanently because of this

I didn't, but it's using the same current like the flash in camera. It shouldn't harm your device if you won't use it for a long time like 15 minutes - just a guess.
As always, use it in your own risk.
Ok.. that's awesome!!!! It's amazing, even if you turn torch on when taking a photo it's brighter that flash itself.. I'm wondering
If there is any chance to boost flash at the same level with camera to get better pictures..

1 of the disadvantages of glass+metal: it heats up pretty quickly,

DANG this is bright, confirmed working for Xperia Z1S I actually kind of blinded myself without even looking at the led directly
If it can increase power of flash in camera, its great. ?

I think it's a combination of low power states enabled for the CPU & digitizer, and a kernel level wakelock. Essential's firmware probably doesn't have that included.

It's actually enabled by having the screen and its touch layer on a separate power rail to allow one to be powered on without sending power to another, this allows it to use very little power and work on some phones but use a considerable amount on others (like the PH-1)

Ok, thanks for the info. I'm guessing the PH-1 doesn't have separate power for the screen and touch layer, thus the high power consumption if we use tap to wake.
I guess a follow up question is does anyone make a battery case for the PH-1? I guess I would be ok with the power consumption if I can get a battery case with 5500mah, that should allow the phone to last a full day even with tap to wake.
Essential have "lift to check phone" menu, maybe for replace doble tap to wake menu ?
I guess if this menu is enabled will make more battery drain.

This is actually the ONLY way double tap to wake works...
If you wake the phone into doze mode... With lift to wake... You can then double tap the screen to wake it up...
So I hypothesize that if you were to use one of the AoD hacks... If they even work on this device... You could probably have double tap to wake

There's a way to do things and then there's a hacked together way to do things. You can make a lot of crap work, doesn't mean it works the best way.
I specifically asked @flar2 about this. Its totally possible if enabled in the kernel, but kills battery. Thats all.

No kidding... I get sick of idiotic apologists making up reasons for no tap to wake without real proven facts. First they come up with BS like "it uses too much power" waah waah! Then they come up with BS aboout how the hardware doesn't support it.
I don't have a PH-1 screen assembly, but just because there is one ribbon cable connecting it to the phone, doesn't mean that the screen and digitizer use the same power rail. Plenty of phones use tap to wake without any appreciable battery drain.

I don't think the amount of cables has anything to do with the power distribution for the screen. You want DT2W? Make it happen.
Edit: also nobody said it wasn't possible, this thread wasn't full of BS until people came in spouting nonsense about how someone else supposedly said it "doesn't support it" acting as if that's the reason it hasn't been done yet on this device.
