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.

I've had this issue with five different ROMs including the stock HTC ROM. It doesn't do it when the ROM is flashed freshly but starts within an hour or so, regardless of whether I load any other software on.
Here's exactly what happens. It doesn't matter if the unit is in standby or if the proximity sensor is activated. (On a phone call with phone by head - backlight is disabled.)
When the backlight is off and is activated by either pressing the power button or moving the phone away from the head, the backlight comes on dim, then goes off, then turns back on at regular brightness. The delay between activating the backlight and reaching regular brightness is around one second.
What is going on? This is really annoying. If I'm on a call and want to mute the mic, I take the phone away and "flash, flash, mute". Then I want to unmute and the same thing.
I don't have any software on the phone right now that most of the rest of you don't have. I've got:
AT&T keyboard fix
Dusk lockscreen
PHM Regedit
Safe Inbox Extender
Clock flip disable
1% battery driver
Theme pack for 1% battery icons
I've reflashed and installed none of this software and the issue doesn't occur. Without installing any software, the issue recurs within a day. (Usually within an hour)
Any help or insight would be appreciated.
Hi am looking for an app that will still allow my phone to dim after so many seconds but not completely off. Anybody know of one or know how to do it with android?

My old phone had a car mode that kept the screen on dim and unlocked. It was real handy for stuff like pandora. I think android has pulled it since 2.2 but im also interested in something like this for ics
Actually this still works, first figure out hoe to launch car mode from that vlingo app or download a car mode launcher app. Next download an app called car dock settings by ig88 and uncheck all the options except disable screen timeout. Now whenever the phone is in car mode after 30 seconds or whatever it will just dim but not lock. There must be a better way though.
You know most phones have had this option in the apps development settings to have screen always on when charging. It would eventually dim but never time out or turn off. I believe it's disabled on our phones due to that it uses an amoled screen. Leaving amoled screens on for long periods of time with a static image will cause the image to be burnt onto the screen. You can try searching the market for screen timeout for apps that will allow this and I believe there were some roms that allowed longer screen time out time and also the development option of screen always on, but just be careful that it will have a negative impact on the life of your screen.

Notification on vibrate mode fail to work after leaving phone unused for a specified period of time. It seems the phone pretty much goes into a half dead sleep mode even though I have disabled as much visible stuff on the power management options. Any way to resolve this issue.
Also this thing takes 3 hrs to recharge fully plugged in straight to a wall outlet.

Don't know about the first part but 3 hours to charge is normal.

What I mean is that if you set the phone to vibrate notifications will vibrate also, like calendar events. But when you leave this phone down for over 20m or so it goes into a deep sleep mode where it practically becomes useless and no notifications come through , the wifi shuts down, pretty much the thing is half dead. Massive power management. And I went through the settings where I changed wifi to always on and high performance, the screen to never sleep unless I hit the lock button. I have a motorola atrix 4g that is rock solid, but this dam thing is barbaric in its power management and also in it's multitasking. It kills everything on the background if it is left there for more than a minute. I might swap it for the Galaxy S3 when it comes out here .
notifications always work for me..?
I have problems with notifications too but not only on vibrate mode.
I always get them when I turn the screen on but if not an SMS notificiation can come as late as 10 minutes after it was recieved. So I guess it wakes up from the coma sometimes to do a check.
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.
so this has been my backup phone for a couple years. my main phone just died so now im using this. I did the system update to 10. And from what ive read, ambient display no longer works. The screensaver only works when phone is charging. I tried the Always On app, and while it did give me a clock on screen while phone screen is off, it just sat in the middle of the screen, even though it was set to jump, then slide. the time never moved and i dont want that, it will burn the screen.
So is there a way to get the screensaver to work when screen is off? instead of only when its plugged in. I dont want to have to pick up or turn the phone on just to see the time.
Custom rom only, but your battery will take a hit.
