I saw the idea posted somewhere previously that instead of getting the capacitive lights on, we really should be putting the phone's AMOLED screen to work ! specially that it doesn't consume any backlight energy when displaying a black screen. So I developed an app that does just that, upon receiving a notification, it will display a black screen with a red dot somewhere in the left top corner. Ok, i really should put these in bullet points..
the application does the following:
1. When your phone receives a notification, it switches the screen on and displays a red dot somewhere in the top left corner. The location of this dot is random every time you receive a new notification. This will guarantee using different LEDs so that the same ones won't be burned out ! The reason why I chose red is because it uses the least amount of energy to display.
2. The app runs as a service, after installing, you'll need to lock the screen once and unlock it for it to activate. After this, the application should run automatically after a reboot.
3. To get rid of the red dot, the only key you can use is the home key. Using the capacitive touch buttons will do nothing, and so as clicking anywhere on the screen. Once your screen turns on, the notifications disappear and will not come up until a new notification sound is received.
I have also logged the touch drivers and saw that although I'm displaying a black screen and setting flags to not respond to touch messages, android is still receiving touch messages when you touch any spot on the screen. This, I imagine, consumes resources! So I disabled the touch drivers when the black screen is active. Pressing on the Home button should reactivate it. If your screen is unresponsive to touch even after the notification screen is dismissed, a simple restart should take care of it. Once you've restarted, you can uninstall the app.
Now the touchscreen drivers were a lot easier to mess around with. The sourcecode given by samsung helped me achieve the activation/deactivation of the screen. Things are not the same with the capacitive buttons. You'll notice that when the black screen is on, if you touch any of the soft buttons, they'll light up (although am suppressing them programatically). Am still analyzing the drivers to see if there is an easy way to disable these drivers too when the notification is on.
One more note, make sure the notification sounds that you choose for your different apps (Calendar, Gmail, Gtalk.. etc) are the default samsung notifications or the ones you placed in /sdcard/sd/media/audio/notifications
Any other sound notifications will simply not trigger the program to display the notification screen.
I just want to let you guys know that this is a beta app. Install it at your own risk.
Enjoy ! Comments and feedback will be appreciated

Thanks for the heads up, but after reading the thread I think I'll wait till it's been tweak a bit more.
That's a good idea, but if it's going to flash using the screen, why no take advantage of the fact that it's a SCREEN and flash an icon instead of just a little red dot?
For example, use the same system icons that appear in the notification bar when messages are received / calls missed, etc. And if you're worried about burning out pixels you could make it change location every minute or so.
Just my $.02
that was mentioned in the original thread... I think it is a good idea... I cant wait to see how this grows...
Does this require your GS to be rooted?

the idea of a full icon was mentioned, but just like a blinking led, the idea here is to keep the notification using as little power as possible. Not sure if the power usage would be more or less showing one pixel or a whole icon.
Obviously 100+ pixels would use more power than just one but the screen is very power conservative. I think it's at least worth a try to see if it really impacts the battery that much.

I have it on my phone atm, it's not rooted. Seems to be working fine.
doesnt work if you have No Lock installed too
Umm..i have nolock and it works fine. Try turning it off, then lock and unlock your phone, and turn it on again. Should work.

How do you properly remove the app? It is screwing everything up on my phone.

It was hurting battery leaving the screen on even though it was just red. I uninstalled it from manage applications and now my screen won't turn on once it is off, I have to pull the battery. Anyone know if doing a clear storage wipes the internal SD card?
+1 for icon notifications
If we can't have a real led, lets look cooler than all the other phones and have little icons of e-mail, sms, and missed calls. It would be nice.
and make them loook purrrrdyyyyyyy iphone-esque
Installed this today and so far so good. Sure it would look better with actual icons but if it saves me from having to unlock my phone all the time to look for new messages then I'm happy.

Not sure why this thread is not getting enough attention when there were so many people begging for a notification app to come out?
Thanks for making the app, will try it out soon. Will give feedback as soon as I get it.
Not working for me at all. Tried default sounds, custom sounds, with puzzle piece, without puzzle piece, etc. Even tried a reboot. Yes, the service is running.
Samsung Vibrant
EDIT: Just worked, but seriously took like 10 minutes before the screen flashed and the red LED started blinking.
I'm having a problem with it as well. I see it running, but it doesn't notify me except for the initial notification. Also it seems to just keep the screen on.
I'll keep playing with it to see off I can figured it out.

I did try that but not much of improvement.
I'm using dagr8s alpha 2 and my phone keeps locking. Like for example when I click a notification in my status bar my phone will lock for some reason. Also it happens sometimes when I click on an app. But the Strange thing is that it is not fully locked. Like I can just press the lock button and it will take me to the home screen. Also another thing is that whenever I enable blue tooth a pop up comes asking me to use car mode. I don't know why this is happening it's kind of annoying. Is this a bug with a rom. Is anybody else experiencing this?

I have hunted and hunted, but can't figure this one out. On my Note 2 I could go to the stock Samsung calendar settings and turn off "Notifications While the Screen Is Off." However, on the S4 I do not see the option to turn these notifications off. I have tried different roms, etc.
I need to keep notifications on so that they sit in my notification bar when I turn the screen on (so, I can't completely turn off notifications). However, I don't want my screen turning on every 15 minutes that I have an appointment (this drains the battery pretty quick).
Anyone know what I'm talking about or what to do about it? By the way, I would go with the stock Google calendar, but like Samsung's much more.
Thanks in advance for any help.
One more try ... anyone have any suggestions? Thanks a lot.

Did you ever figure this out? I'm having the same problem. I get the notification, but it keeps the screen on until I acknowledge. I don't usually notice until my pocket gets really warm, then I realize the screen's been on the whole time.
I adjusted my home screens the way i wanted them, and then some time after rebooted my phone. When it booted back up, one of my screens was sitting over top of the smart tips and fitness screen as shown in the attached picture. I cant remove the icons and i have tried turning off smart screen and turning it back on, but it stayed the same. I cant think of anything short of a wipe and restore that would fix the issue. Has anyone else had this problem?
