One of the more interesting developments over the last year has been floating apps. They are essentially apps that run in a re-sizable window like a desktop operating system. Some OEMs have used the idea to some extent, like Samsung’s multi window feature and Sony Small Apps. Not all devices have access to floating apps. Now, the Samsung Galaxy Tab 2 can use the re-sizable web browser commonly found on the Galaxy Note 2 thanks to XDA Senior Member pidio1.
Once installed, users have access to a floating, re-sizable browser on the Galaxy Tab 2 to use instead of the stock browser. With the large screen real estate on the Tab 2, the feature is surely useful to those who want to browse while performing other tasks.
So far, users have confirmed that it works on at least stock ROMs. It was tried on one unnamed custom ROM and it didn’t work. So if you’re running a custom ROM, it’s worth at least trying out, but don’t get your hopes up too much. If you want to uninstall it, simpley remove the PopupBrowser.apk from /system/app.
