Switch Between Your Two Most Recent Apps Faster with a TV-Style “Return” Button for Android
There are a gazillion app switches on the market, and some are really awesome, like Edge, GloveBox, Loopr, and Switchr, to name just a few. However, these can all be a little bit more complicated and cumbersome than necessary when I just want to switch back to the last app I was in.
Television remotes got it right with the "return" button, and that's exactly what I want on my Samsung Galaxy S4—a way to jump back and forth between my last two apps used. This is especially important when using social networking apps and clicking on different links that either bring up our browser or video player.
