One of the cooler features of the Samsung Galaxy S III is called SmartStay. The feature utilizes the front facing camera to detect whether the user is looking at the phone. If the user is, then Smart Stay makes sure the phone screen stays on so the user can continue to read or do whatever they were doing. If not, it’ll shut the screen off. It thus more accurately controls the screen based on how the user is using it. Well, the Galaxy S III isn’t the only phone getting an application like this.
XDA Senior Member elnoxvie is running beta tests for a similar app. While posted in the Galaxy S II forums, there are reports of it working on other devices such as the HTC One X, as of the most recent update.
The app is easy enough to install. Simply download the beta and install it. From there, the app works nearly identically to the original. The app runs in the background—reportedly with very few resources needed—and the front facing camera monitors whether you’re looking at it. Then it deals with the screen accordingly.
The beta is only open til the 29th, when lite and premium versions will be released on the Google Play Store. Despite the list of known working devices being mainly newer, high spec’d devices, this application should work on nearly every phone with a front facing camera.
