Not too long ago, we covered an app here on the Portal called Screen Standby. The app allows you to turn off your screen while streaming over HDMI or MHL without putting your device to sleep or killing the stream to your TV. This has a very significant effect on battery and screen life since it is essentially not on while running. Well it seems that XDA Forum Member nkahoang was not happy with the app, so he did what any good dev would normally do: He updated it and added a load of new features to what was an already awesome app.
The new version of Screen Standby offers a few new perks such as a non-root method, which essentially means that you will be able to use this even if you’re not rooted. Other perks now include the ability to turn your device, with the screen off, into a wireless touchpad. So, if you were thinking of a good use for that device that you have had sitting in your drawer since you upgraded, this is a perfect time to take it out. We have seen a few other apps capable of turning your device into a WiFi or Bluetooth input device for your computer, but they all require your screen to be on for them to work. Last but not least, if you shake your device, you can either turn your screen off or put it in dim mode—the lowest possible brightness.
So, if you were a user of this app before, be sure to check it out now and all of its added functionality. As always, please report any bugs or issues you may run into.
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).
