Adding a feature to select an external camera through the micro USB or USB-C port would be helpful. There are not really any good apps for external endoscopes/cameras; the ones that are out there either have a garbage UI or are full of ads. I know they only work with android phones that support OTG so may need to make sure people know that requirement. It's a niche market but even the garbage apps have 100K+ downloads.
