Samsung's S View cover lets you peek at your Galaxy S4
The phone can sense when the cover is closed and switch to a minimized view when new updates arrive, putting the information in a tiny window that lines up with the cover's cutout. In this view, you can get access to information such as the time, battery status, the current music playlist, and caller ID.
It's a minor feature, compared with some of the more buzz-heavy things about the S4, such as its photo and translation features, but potentially handy for those who are constantly pulling their phones out of their pockets to check for updates.
There's no word yet on how much the S View cover will cost or when it will be available.
