is there a software to blank screen (lamp) after a specified idle time and wakes up once an activity is detected.
yes its called the power settings > Advanced, it turns off the device after a specified number of minutes
There are screensavers out there but why have another app to suck up resources.

I have a small problem with my Artemis.
Power settings (to turn the device off) are not remembered. Even though I ticked yesterday a box in Power/Advanced to turn it off if not used for 1 min it's not stored (initially it's ticked but after some time it disappears) and my Artemis stays on until I turn it off or the battery is flat.
Since we need to have the screen turned on to keep wifi/gps etc. running, and there are a few apps that would ideally run in the background with the screen off; to save battery power (and burn in?) it would be nice to have the AMOLED screen display just a black image.
Is there any app out there that just displays a black screen and maybe ignores all but a specific input?
At the moment I just zoom into a black image in the browser, but I can't put the phone in my pocket like that.
(I tried searching for this, but it was beyond my google-fu.)
You dont have to keep the screen on to run either my gps is always on and it neva disconnects also ive spent many nights going to sleep leaving my wifi connected and its neva disconnected either
Yup. If you haven't set WiFi to switch off after 15mins, it should carry on running.
By doing what you proposed, you'll decrease battery life drastically as you'd effectively be disabling the chips sleep mode by keeping it running 100%. With that, only the screen switches off and everything else including Android keeps running. Any application holding a partial awake lock can achieve this.
Lock delay; an app to control the default screen-lock options allows this.
For instance, if you set the initial screen timeout to 2 minutes but standby/lock to 10 minutes in the settings, the screen will switch off after 2mins idling, but the rest of the phone will still be running incl. WiFi/GPS. You can enable a lock/pattern or no lock at all where you press any key including menu/trackpad and it'll come back on in the same place you left it, without any lock. If the phone idles for 10mins, it'll activate the screen lock and place the phone in the standard sleep mode. The max delay you can set the latter to is 24 hours.
I wouldn't advise avoiding the sleep mode unless required in specific circumstances. Battery loss will be drastic; I found out unintentionally when activating this option at the beginning.

Thanks th3, that should do what I want. I don't intend to leave it unattended, it's just for when don't need the screen on while an app is doing something.
How do I find out which program or programs are keeping the screen active?
I'm running the stock rooted software without Knox and clockwork recovery.
Your screen should go off by itself after a certain amount of time if you're not in any app (aka, on the home screen)
Otherwise, your screen off delay is set to something high. You can change it in settings > my device > display > screen timeout

its currently set to 15 seconds and the screen does not turn off, if I reboot the phone the screen will automatically shutoff like its supposed to however after a short period of time (maybe an hour?) the screen will no longer automatically turn off. This is why I suspect some program I have loaded is preventing the screen from sleeping.
-TL
after some trial and error I found the program keeping the screen active, it was Handcent, as soon as I uninstalled the application the phone would shutoff like it was supposed to.
It's a shame because I liked the interface it had.
New 'out of the box', I have turned the lock screen / sleep setting to (never). The device still goes to lock screen mode in 5 seconds in all none active applications.
Although I have set a number of my apps to have unrestricted battery usage in "battery and performance" settings, Note 8 keeps shutting them out on screen lock (after a while at least). Is there another setting that overrides my power management settings?
