You can rotate the snap in the Media Editor by 90 degrees each time you press the Rotate icon.
If your snap doesn’t fill the screen, you can press the stretch button once to make the snap fullscreen. This will crop the sides or the top and bottom for it to fill the screen.
Pressing the stretch icon again will unstretch it.
From the Media Editor you can press the Horizontal and Vertical flip buttons. These will flip the image back and forward between the selected type.
If your phone has a small screen, you may have to scroll the toolbar to see the icons.
Note about Videos
Please note, videos can’t be rotated, stretched or flipped. If you would like to do so, please download a video converter app from the Play Store.
