Most Android phones and tablets have pretty good
cameras, and Jelly Bean makes it easier to review all the shots you've taken on
your device. From the Camera app, you can tap in the lower-right corner to see
the most recent shot you've taken. You can swipe left and right to review other
shots, but if you want an even quicker way to see what's on the camera roll you
can pinch inward to see your shots lined up in order -- just like a film strip.
Bonus: you can simply swipe up to delete any shots you don't want to keep
