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.

Hi there,
Has any of you have any luck changing the color (and/or blinking behavior) of the notification led (e.g. when an sms is received)?
On my CM7'ed Desire I had full control - e.g. from Go SMS - but with this Desire X I'm stuck with the default green blinking.
I just rooted and flashed Elegancia on today, hoping that would put me (or the apps, actually) in control, but no...
BR,
Egholm
I believe there are apps that will let you change your LED on your phone.
Sent from my GSM Galaxy Nexus
Only two colors on Desire X if I remember correctly.
Why would you want to change the colour. Maybe i am missing something .:cyclops:Green seems ok and orange when charging is also ok.
hi
Missed call or SMS -LED flashes only 5min.This is the problem.
ORA1: It's annoying that when I leave the phone at home, and a notification-event occurs that I don't hear, I cannot see from the LED which event happened (remember I didn't hear, I just glance at the phone every and so often when I pass it). Then it's super nice to be able to see if it is a missed call, an SMS, an email, and so and so forth.
Also, the standard blinking behavior - blinking briefly every 1-1.5 seconds - is silly. It requires starring at the phone for a second to judge if an event is there. A constant LED is much nicer.
That's why
Klapo, yeah, but mixing the red with the green, you get an orange So, three colors, and if I could control the blinking, that's infinite combinations ;P
Obj261, after trying different apps, I stumbled over "Light Flow 3.5.2 (lite)". Its the only one that I've seen being able to control the LED succesfully. But obviously I'm too stupid to make it work (consistently) beyond the "testing capabilities" from within the app
I hoped that others have had this need, as well :/
I would just want to know if it's RGB or just green/orange.
I would love to control it via LightFlow but the hardware must support it first.
katman4, it's only green, orange and red.
(But still I haven't found the magic setting in lightflow that makes it work consistently, so be aware of that)
Now someone can design an app that when you have a notification of any sort the whole screen flashes in a colour.
Cant be too difficult for one of the boffins to design:good::good::good::good::victory::victory:
I have looked up down left and right and I have come to the conclusion that it might not be possible. But when we turn our phone on or off, the notification flashes blue then green before it flashes off. I was curious if anyone knows if it possible to apply that to notifications such as messages and what not. I have tried every light control app I could find and both I could find for xposed. Thanks for any help or info!
Hi, I bought new "Cubot Note S", what I discovered in the first use was "display whitish" lines lying vertically, when set to high brightness.
At first, I thought it was hardware problem, but later I observed, actually those white(ish) lines are present when:
- screen brightness is higher than about 70%
- and when display is showing darker colors (mainly for notification bar)
- or when using camera.
And also, when moving notification bar up and down, those "whitish" lines moves sideways!
I found one solution for this problem, with the help of "MiraVision" user mode settings, by altering "Color temperature, brightness, and contrast".
You can see the problem and solution in the VIDEO.

Questions:
1) Is it really software error, or hardware problem?
2) If it is a software problem, is there any stable custom rom for "Cubot Note S" ?
Thanks!

Send the phone back to where you got it for a refund.
Many traits with the cubot note s include -
Doesn't boot up and hangs.
Boots up and the sim icon is missing.
Screen burn.
Boots up and sdcard missing.
Problems connecting to wifi.
The ota updater is dangerous and should never be used.
It has a couple of malware apps in system.
Volume button not working as it should.
There are also lots of pro's of course so it is worth £50, but only £50, no more than this.
I know the title sounds crazy, so let me explain.
I've had this issue for quite a long time now but never gotten into it.
Basically, when I open a white image or whatever light colored app/background, I can recognize a Whatsapp conversation in transparency, almost like it's stuck underneath the display.
So I tried opening the recovery to clear cache and I noticed the same exact thing when the recovery was loading (light blue background).
You can find a picture below. The top portion is my phone's display while the bottom is a screenshot found on Google (cause I needed the old layout for Whatsapp chats).
By the way, the phone I'm having trouble with is a Samsung Galaxy S6 Edge updated to Android 7.0 (the update didn't fix the issue).
Thanks to everyone in advance
This is known as image retention or burn-in. It is a characteristic of OLED/AMOLED displays when the same images are held at high brightness/intensities for long periods of time. There are apps/tools/methods which claim to reduce, remove or in some way fix the problem but please do your research as there is a good chance they can make the problem worse or introduce new problems. I have not investigated further other than methods of prevention. Also, organic light emitting diodes/pixels have a given lifespan. The screen will lose brightness and color accuracy over time. Blue diodes will fade first, then green, then red.
