The ten commandments say not to covet your neighbor's wife or house, but they don't tell you not to lust after his Android phone's features. If you wish your phone had a floating browser window like QSlide on the LG Optimus G Pro, a video player that appears on top of your apps like Pop-up Play on the Samsung Galaxy S4 or an automation service like the Droid RAZR M's Smart Actions, there are apps that can perform all those functions.
Search the Google Play store for "floating apps" to find programs such as Floating Browser Flux and Super Video that run in draggable, resizable windows. Also, look for automation apps like Tasker that program your phone to do different things based on your calendar, location or other conditions. You can even configure the app so your phone doesn't ring whenever it sees a meeting on your calendar.
