OK, so I REALLY wanted to get this thing going and working as it is supposed to, as an app to simply turn the screen and digitizer off.
After trying this thing for weeks, I still can't get it to work reliably. In other words, sometimes it works, sometimes it literally drains the battery in a matter of an hour, noticeably overheating the phone in the process (Unrooted Galaxy Note 2, Jelly Bean 4.1.1.)
Furthermore, and a bit of advice for people who would turn the screen off and CAN'T REMOVE THEIR BATTERY... How are you supposed to be able to press the ON button if the screen is OFF and the digitizer DEACTIVATED???
Maybe someone can shed a light on this, but I cannot understand why a simple screen on / screen off switch can not be implemented, as in "press the power button to turn screen on or off"???
Maybe we should be looking into how android manages to play music with the screen off and use that same function as the basis for this utility!
Don't hesitate to fire away... I'm looking for answers here!
just wanted to say that it works perfectly on my nexus 4 android 4.2.2 with latest radio / bootloader
Hi! First of at all thanks for developing this great app. It really saves a whole lot of power while playing games. However, i still have problem with video playback. Before i play the video, the screen would stay off. Then it would turn on immediately the moment i press the play button. It happen s with both YouTube and MxPlayer. I turned on 3d UI rendering. Could this be the problem? I'm using Samsung galaxy s3 and currently using Samsung based custom ROM (crdroid). Thanks again for the great app!!
okay i missed the Disable HW Overlay part. now it works like a charm! awesome!!
Edit: Never mind. It was just a coincidence that it froze when a text appeared. Looks like it still has the same freezing issues. The voltage cut method doesn't work at all, but that seems to have been the best option at one point.
The digitizer is not disabled by default, so you should still able to tutn off the app.
I implemented the screen on / off using the power button already.
And if you look back, you may need to turn on "Disable HW Overlay" for the app to successfully work with Samsung's AMOLED-screen devices like your note 2. Lots of Note 2 users report my app work with their devices.
If you encounter a problem, please post a log or I can't help, really. Actually, having to support devices while not having those is very hard, please understand for me.
Android playing music with screen off is different from my app architecture. Music ppayer is a service that is designed to work while the screen is truly turned off while my app intent to help services (like map/navigator/hdmi streamer/etc) that don't have that ability to be able to continue their operations while the screen is off.
And about the complexity of the app... Well, I need to update the app with features. It brings new functionality and usability to the little piece of scripts (seriously, I still try my best to improve the core screen off methods but nothing much can be done now). Without added features and updates, my app would have been forgotten and buried somewhere deep in XDA forum. Please understand this. It is also a very fun process that everyone can help participate in.
when i try to play 1080P video on my xiaomi mi2 i get a blue screen & the sound of the video, when i turn the phone screen back on everything is working fine. any solution ?
Two solutions:
1) If you are running JB : Go to Android's Settings -> Developer Options -> Tick on Disable HW Overlay
or
2) If you are not on JB, Go to my app's settings -> Screen off Methods -> Disable 'Persistent Blank Frame'
Can you also gives me a log?
------------------------------
In latest 2.0 alpha builds, printing the log is done as Go to menu (or click on the three dot [. . .] button) -> Print debug info
has anyone tried this with something like webkey?
so basicly having remote accsess to the phone (to use whatsapp for example) via wifi or usb without the display on?

CooLoserTech·Top 10 Best Apps of the week # 171
INTRODUCTION
Hi everyone,
This is originally for HTC One X, however, I have ported it to the Galaxy Nexus and now it could work on all devices! (Galaxy S3 / Moto Razr / etc). "Screen Standby" will completely turn off the backlight while keeping the phone running for MHL / HDMI streaming|gaming. That means you can now watch movie / play games on big screen and can still turn off the screen (touch screen still works!).
FEATURES
- Switch off the screen temporarily without actually putting the phone into 'sleep mode'. The phone is still running! It saves your battery, avoids heating to prolong battery life
- Since 1.96, screen can be optionally turned into touchpad!
- It has a nice little widget that let you quickly turn the screen off from your homescreen
- Since version 1.5 beta 2, shaking your device will temporarily toggle between complete screen off and lowest brightness level (so that you can perform quick action without playing a blind guessing game)
- Non-root method now available with 1.98 Beta 7
- One two dimmer: Turn off screen automatically after an idling time (no user interaction)
- Simple interface
HOW TO TURN ON THE SCREEN AGAIN?
+ Click on the app notification on your status bar (since version 1.3) or
+ Simply put the phone into true sleep (short press power button) then turn it on (power button again)
+ Temporarily lid the light a bit by shaking the device (since 1.5b2, enable it in Menu -> Settings)
+ If you can't turn on using any of the above methods, press emergency button (in main app interface) to turn on / or use 2 by 1 widget
Installation
Install as normal apk No big deal
Remember, install and use as your own risk, even though I can't think of any damage this little app can cause to your phone
Changelogs:

Please help me) and your use-case (Streaming movie / Playing ingress / Playing Youtube etc) and the wizard will automatically select the optimised preset for you!
- New! Screen Standby Search Plugin to help automate Screen Standby from Search key (long press search hardware-key or softkey) or Google Now gesture (swipe up from Home softkey on Jellybean device).

- Added new Tasker intent to control screen standby:
com.nkahoang.screenstandby.action.TOGGLE : to toggle screen on and off automatically
com.nkahoang.screenstandby.action.REMOTE_CONTROL: to launch Remote Control from tasker
- Added new option to broadcast an intent to Tasker when HDMI is detected (go to my app's settings -> HDMI Detection -> Enable broadcast on HDMI Connection/Disconnection. Specify intent action (case-sensitive) for each case. Go to tasker, add New System Event -> Intent Received, type exactly the action intent you provided in Screen Standby). The best part is, HDMI Intent can also be broadcast without activating Screen Standby (yeah, so you can use SS as a HDMI sensor for tasker)
