Samsung’s new TouchWiz icons are cool and all, but the company hasn’t exactly gone and made custom icons for every app on the Play Store. To circumvent this, it simply adds a frame to existing apps to make it look similar to Samsung’s apps. This is on by default, but it is possible to turn it off in case you prefer the way the app was meant to be seen.
Of course you can always use an icon pack to get your own look, but Samsung’s new icons actually look pretty good. If you’re someone who likes to keep your phone running a stock launcher though, you probably want to know how to turn the icon frames on and off.
