Most Galaxy smartphone owners are aware of Samsung’s Multi Window Mode, which allows you to run two apps side-by-side on the home screen in separate windows. However, some users prefer having a floating window that appears on top of other apps.
If you’re looking to do some serious multi-tasking on your Galaxy S4, try GPC’s Floating Browser Flux. The app does exactly what its name implies—it’s a classic Web browser that you can move anywhere on the screen while other apps are open. You can open up to 10 windows at a time in Floating Browser Flux and resize them as you please.
