In the app’s video settings there is the “video stabilization” option, which you can try. This will reduce the video shaking, but often reduces the camera angle as well. Please note that on some devices (especially Samsung ones) enabling this option may cause corrupt videos.

Only the Pro version allows camera selection. When opening the app for the first time, you can choose which camera to use. Then your selection is saved, and in the current version you won’t be able to change it later (only after reinstalling the app). On some devices the system prevents regular apps to access all cameras, so if you can’t use your preferred camera in the Pro version, we’ll refund your purchase.
