App to display a black screen/pseudo lock?

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.

[Q] Anyone having issues with the automatic screen shutoff?

I am running CM 6.1 Stable, and have been for a while, yet this issue just popped up a few days ago.
I cannot get the phone to auto shutoff the screen when idle. I have it set to 5sec off and 1 sec lock, (down from 30 sec off, 5 sec lock before).
I have looked at the stock settings and all are in order.
The only thing different is I was trying to play with the setting on my Alarm Clock Plus regarding screen setup, but have reverted to original settings and even rebooted several times with no success.
Anyone else having issues with this? Any way to enable screen off again without having to flash a recovery?
It's really killing my battery fast!
Thanks for you help!

In the android display settings, 15 seconds is the least amount of time to turn off display. how is yours set to 5?
In cyanogenmod settings, theres options to tell the lockscreen to kick in after the screen has automatically turned off and when the user has pushed the power (sleep) button. what is your time set to in the android settings? (settings - display - screen timeout)

Um....finding rock, and hiding underneath it!!!
Turns out I am a moron that can't read.....but I swore that I had the display set to 30 sec....It was disabled. I will test again, over the next few days if for some reason it reverts to disabled.
Thanks!

Using Tasker to save that battery

Just thought I would post some of my tasker setup to make my battery last a very long time!
First you need Tasker
You also need Secure Settings
And lastly you need Synker
if you want to make my settings super easy to install just download the two attached files and place them on the Sdcard in the Tasker folder.
userbackup.xml
userbackup.xml.txt
then start Tasker, click on the menu button and select Data then restore. This will place all my prebuilt settings in for you.
The first profile I have is Mobile. I have this profile made for when I am in my car but its settings are for anytime power is plugged in.
The things it does is: Turn on GPS, Turn off auto brightness, turn display brightness to max, turn auto sync on, turn media volume to full, turn display time out to one hour.
When unplugged from power it does the following: Turn off GPS, display turns off after 30 seconds, Auto brightness on, Auto sync off, wifi off.
The next setting turns on GPS automatically once maps or navigation is started then turns it off once you exit those apps.
The next one is the big battery saver! When the display is off it Turns off mobile data and wifi.
When the display turns on it will wait five seconds and then turn on mobile data.
lastly I have it setup to turn on mobile data every 2 hours and sync gmail then turn mobile data back off.
I have had tasker for a long time but never really dug into it until I got the SG2. I think this will make your battery last much much longer.
If anyone has better suggestions please add your input.

i have the same setup but use juice defender to do the same thing as tasker and synker. it can actually more, like sync more or less at certain times of the day. but i've been thinking about switching to tasker, might be more battery efficient.
i'm using secure settings to turn gps on\off too, based on what applications get run. i noticed the little tray icon only turns on when an app is actively using the gps tho. does that mean gps only uses battery when actually in use? but it seems like i get more battery with it turned off completely.
for mobile, i'm going to attach gps to my car's nfc sticker instead of when plugged in. might be a little faster for charging at home.
i guess you could use secure settings and tasker to only turn nfc on at the lockscreen. although i'm not convinced nfc uses much battery.
lets see... i'm also using tasker to immediately turn off the display if upside down (in my pocket).
it turns data off if i'm reading an ebook or watching a video.
i use it for 1 click switching between 2g and 4g.
i use it to switch cpu max between 192000, 918000, and 1728000. you can get crazy battery life by running 192000 all day, but everything will run slow. usually i keep it at 918000 and play games at 172800.
there are lots of other things, but that's the battery stuff.

Hey ,I just wanna say thanks I was getting 8 hours on a Verizon extended battery but now using your settings and tasker plus extra apps I'm getting 14 to 15 ,I just wanted to add that it in order to use secure setting you have to root your phone but it worth it.

Do you still have these backup files? The links are dead when I try them. I would like to try out your settings.

Reupload please

First post and it's a necro asking for something. I swear I used to have an account here in high school.
Anyway, I think those files are gone. Every time I come back to Tasker I try to start from the group up and a day later I'm fiending for backup.xmls/txt just whatever you use for your battery, please, just a quick string of code.

Always on display "flickering" when activated (on tap)

Hey everyone!
As the title say i'm facing a issue with my always on display.
I'll try to make it as simple as possible:
When I set the always on display to be always active it works flawlessly.
When I set the always on display to activate on tap (and last for 10 seconds according to the settings) it appears for roughly 3 seconds and then disappears for 3-4 and reappears flickering for 2-3 times sometimes showing the desktop wallpaper between each flicker.
Did anyone experience the same issue?
What I did to try and fix it was:
- tested both on battery and while charging
- factory reseted and then restored backup (which was stupid, that lead me to the second point)
- start in safe mode (to check whether it was an app causing troubles) but no such luck, problem still occurs.
- uninstalled "nice lock" apps
- changed some settings under the always on display tab
- cleared cache of the always on app
What you should know:
- I'm running android 9, not rooted and have nova launcher as default home
- After I factory reseted the phone I wanted to stop always on display from updating to test whether it was a new version issue but I forgot and didn't make it in time so I'm currently running the latest version
Does anyone have any idea as of why it's behaving like this?
edit: just wanna be a little more clear, flickering is not meant like a lightbulb it's more something like it turns off and back on after a delay (I'm sorry english is not my native language I can't really explain it any better)

i also experience the same.
this phone has many strange bugs.
when i restart my A70, tap to show always on display works for me for 2-3 times.
after 2-3 times working correctly, the bug starts.
after i tap the screen, it shows AOD for 2 seconds. then turns the screen off and then at the end of the 10th second, screen just flashes itself for the last time and turns off completely.
i think it is related to the fingerprint scanner.
because after i registered my fingerprints and turned on unlocking the screen by the FP reader, this bug ends.
after i tap the screen it shows both the clock and fingerprint icon at the bottom of the screen.
after 2 seconds fingerprint icon disappears. and the clock is continued to be shown until the end of 10th second.
but there is a minor issue, when the fingerprint icon disappears, the AOD screen brightness changes. dims or brighter slightly.
can you please try tap to show AOD, by enabling the fingerprint unlocking?
samsung ?

Hey! Thanks for the answer, I can confirm we have the exact same issue. I also have the same brightness issue you described
Anyway, I have always used fingerprint unlock though so I don't know what to answer you.. I only recently noticed the weird behavior. I did a couple things to test and I found out that enabling the "fingerprint" icon showing in the always on display seems to "fix" the issue of the flicker but not the one of the brightness change (after enabling it i've yet to see the problem occur), you should try it and let me know if you see any improvement. It's probably on samsung's end though and hopefully we get it fixed with android 10 or earlier
I'll take this chance to ask you another question; two weeks ago I received a software update and ever since that day I noticed my battery to be lasting waaaay less than it used to, did you update your phone as well? Did you notice a battery drain?

I have the issue both of you talking about.

hello, I had this same issue and what I did was turn the phone off, and booting it up while pressing "Volume Up", after entering a black screen with many options, I selected wipe cache. It has worked without a flaw since then. There's lots of bugs with this phone. I recently had a problem where the USB port will detect a device and "plugged and unplugged" it, making my phone unable to dim. Thankfully I was helpful.

Question Turn on Do Not Disturb manually at night, have it turning off in the morning at exact hour

Before Do Not Disturb even existed I used quite a few apps (llama, Phone Profiles Plus, Sound Profile) to achieve sound management over night. Unfortunately at some points in time some of these failed to work due to more aggressive battery management of my newer phones or after software updates that broke things.
However now I feel that DND provides more options and is a more elegant solution...if it would do what I want.
I would like to turn it *manually* on, go to sleep, and have it turned off at 8:00 AM. Anyone found a way to do that?

You can set a schedule to turn on and off automatically. You can also turn it on manually then set it to turn off automatically. You select how many hours you want it on.
