I've got a Nexus S phone with an amoled screen and I was wondering, is it possible to make it so that when the screen is turned off, a clock appears on the screen?
I remember some nokia phone that also had an amoled screen and that had a neat feature; whenever the screen was turned off, there was an always-on clock that'd show up, and since the clock was small and the rest of the screen stayed black, it didn't drain the battery.
I mean, that'd be a pretty cool thing to have on amoled android phones, no?

did you try ?

looks like this app does what you want
That's pretty neat but all it does is prevent the lockscreen from showing up and everything else works, touchscreen and capacitive buttons included :c I was more looking for a clock that would show up after the screen completely turned off and where neither the touchscreen or capacitive buttons would work
you looking for something to display at all times ?

this app allows to set triggers with different light levels
means you can set your phone to dim level near 0 or 0 itself and set trigger when you lock screen(any lockscreen (with clock)) it will start its work and keep device screen "on" but not off
btw you will never get deep sleep if this is on

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.

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.

Hey
Since ics, multiple one touch lock screen widgets dont work properly. The led will flash and the it goes to the lock screen and times out with some, and with others it stays on a very low ambient type mode. Any one else? Any suggestions, i love one touch to lock the screen, damn first world problems

I just turned off the lock screen, hardly needed since there are only soft buttons on the front of the device, and it's unlikely the power button would be accidentally pressed in one's pocket. Then i used a cool app called screen off and lock, it even has crt effect.
Hello,
the following problem appears when i try to unlock the phone after some hours: i can see my home screen, but the screen stays extremely dim. When i try to start an app (e.g. browser) the screen turns black. I can unlock it again, but the screen stays dim. after some unlocking the screen becomes normal (normal brightness) and also the apps are startable.
i am using autobrightness, the stock firmware, 4.1.1 (i9300xxdlih) power saver is not turned on.
thx, i hope you can help me solving this problem

i updated mobile phone to android versiopn 4.1.2. this morning. Unfortunately the problem still appears.
Maybe its a hardware defect?
Try to disable somehow light sensor and change settings to non auto brightness.

i disabled auto brightness and set the brightness to the highest level. But its still same: very dim and after a while a black screen; after a few times of unlocking, the display works normally
I have just seen the same issue on a friend's S3.
Anyone else? I feel like this is a very big issue that is still lurking in a lot of devices.
I tried it myself and I toggled the power button to turn the screen on and off.
It doesn't take long but sometimes when the screen turns back on, it's super dim and you can faintly see the lockscreen image.
You have to cycle the screen several more times to get it to the 'correct' brightness, and no it is NOT a brightness setting.
It's some hardware issue in the phone.
Sorry for the necrobump, but I only found this thread. I have this problem too since about a week back. It makes my phone useless at times. I first thought it was a software issue. I have an app (called Twilight) for dimming the screen more than normal settings and also toning it, for nightime use, and I thought that was the culprit first, but nope. I have flashed rom, recovery, wiped all caches I can think of. Still happens, just now I was in the middle of installing android revolution hd, and the screen ultradimmed on me so I can't finish the process
Thing is, a few months ago I managed to crack my screen by way of gravity and concrete. I let the samsung brand service centre in Stockholm repair it for me (it is out of warranty) and this issue with the dimming never happened before that. Then again, it didn't happen directly afterwards either... but still. So, I am thinking: either me dropping it caused more damages and this is because of that. Or the service center did a bad install of the new screen. Or, the replacement screen that was installed has a defect in itself. I am leaning a bit towards the third explanation... maybe different batches of screens?
Does anyone have any ideas? If I am to contact the service center and complain about their work I would like to be able to point towards a "known problem"...

Take it back, if it didn't happen before then the new screen is most likely.
It isn't a common problem
Hey guys, I got my phone last Saturday and have been playing around with it ever since.
I noticed that I had the night clock bug (whole screen is lit up) and as far as I know it's already a confirmed software bug. What I also noticed though was that my lock screen is also lit up. I'm using a pure black wallpaper which works well when the phone is unlocked (appears pure black) but the black is lit up when the lock screen is shown. It's almost like there's backlight bleeding. In the home screen and lock screen preview though it shows that it should be pure black
Here are screenshots of the "bug". I'm actually thinking it's a software bug since it was captured by the screenshot. http://imgur.com/a/p5maP (Take note the the blacks on the first image is different from the other 3)
Was wondering if this bug is related to the night clock bug or a defect with my unit.
If anyone is willing to help, kindly try changing your wallpaper to a solid black color and check if the blacks on the home screen and lock screen is different.
Thanks! (I have 4 days left until I won't be abe to replace my unit so I'm trying to make sure everything's good)

They're referring to the Night Clock alone. I have that problem as well as a lockscreen problem. Haven't seen anyone reporting if they have the lock screen problem so I'm trying to figure out if it's a software glitch or a bug with my unit.
Basically the lock screen preview when applying a new wallpaper shows that the lock screen should have super amoled blacks but when I lock the phone the black is lit up.

If there's any consolation I experienced this very problem. Were you using fingerprint to unlock? I hadn't seen it because I had swipe to unlock.
I still haven't figured out how to fix it.

That's normal. This happens because the lock screen puts a slight filter on your wallpaper. It de-saturates the image. You can try with a solid red color, it might be easier to see.

Not, really. This only happens when you have Fingerprints/Pattern set up as your Screen lock type.
If you set it to Swipe, with the water droplet effect, there's no "filter."

Yeah it's clearly a bug, but OP thought it might be a defect of his phone. I was just reassuring OP that the problem exists in my phone as well. Thanks for that link. I did try the solution they proposed but it didn't work for me either...
Solution not working...plz another fix?
I have the same bug on my Galaxy J5 (super amoled), I use pin to unlock it. It is pretty annoying. I use the same black picture for both lock screen and background pic, and after unlocking the phone, black backlight turns off. Swipe to unlock solves the problem, but I have to take one of the disadvantages : either backlight or not locked phone.
Download "klwp live wallpaper maker" from playstore and make a all black wallpaper . Save it go to settings ---> background/wallpaper, set KLWP as lockscreen and wallpaper/background.
Not solved? are u using xposed? if so, download Bright Lockscreen and see if this helps.
Hello,
I'm experiencing a weird problem with my LG V30 H930 and I was wondering what could be the solution, if anyone has ever experienced that as well?
Yesterday I received a new LG V30 phone and that day I found something very disturbing. The "always on display" function does not work when it's too dark in the environment or when I cover the light sensor. This also results in:
- "double tap to wake" function does not work when it is too dark
- holding finger against the screen results in turning off display instead of entering options for changing wallpaper, adding widgets and settings. Additionally when I turn off the screen in this way, I need to press the button on the back of the phone twice, which is also a fingerprint reader and at the right time. If I do it too slowly, i.e. press the button once, wait a bit and then the second time, the screen will not turn on. I have to press it twice and relatively quickly
All of this does not happen when it is bright in the environment.
The phone's never been rooted, there is no custom firmware loaded on it, I've tried many times going back to factory settings.

Why are you covering the light sensor if you want the AOD on?
You are basically replicating a flip case cover or flipping a phone over on the desk. Of course the AOD will turn off under those circumstances. There's nothing wrong with your phone.
With your display on, just quickly press your finger on the fingerprint sensor to display lock the phone and you will see AOD. Well you also have need the "power key instantly locks" option turned on. But I assume you have that on already.
Of course the AOD works in a dark environment. But in this instance, you are covering the light sensor -- which tells the phone you must have it in a flip cover case or flipped over. When you open the case or flip the phone back on, the AOD comes back on. In your fake way, you must be doing something wrong.
Stop covering the light sensor.

I understand your logic, but it is a very weird feature then, not to be able to change wallpaper directly from the home screen, when it is dark in the room or not to be able to turn on the phone double-tapping the screen, which is turned off. Is it perfectly normal as well?

You can change wallpaper and double tap the screen, but go to AOD mode in a NORMAL way. I told you how. Just turn off the display with the fingerprint sensor. AOD. Double tap, display back on.
