For years I've been using MoviePro for this, but it's starting to get buggy: 1. When I record in 60fps and switch to the front camera during a recording, the front camera is upside down 2. When I record in 60fps, the camera keeps constantly zooming. Not smooth zooming (like when I set MoviePro to 30fps, or in the default camera app), but a jarring back-and-forth zoom. I forwarded this feedback to the developer over a year ago, and it hasn't been fixed yet...so I'm looking for another app. I've found some apps that have the front/back switching functionality, but not at 60fps. Is anyone aware of a video camera app that supports this?
