SmartStay Ex is an easy to use and free app that implements one of the coolest features in Samsung Galaxy S3, the Smart Stay. The feature uses the front facing camera to detect whether the user is looking at the phone and 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 and you can get rid of the annoying action of having to turn on the screen or touch the screen so that your screen stays on.
SmartStay Ex uses the front camera of your phone to keep track of your presence and help you keep the screen on. It automatically recognises that you are looking at it, whether you are reading an e-book or browsing the web. The front camera maintains a bright display for your viewing pleasure.
