microphone could be related to expo's handling of automatic permissions (albeit I never had this prompt on my device?)

Ability to delete content on phone? Why?

To move saved images to separate folder instead of just saving them to camera roll, which is just polluting the phone for no reason.

I'll see what I can do about microphone permission though, but entire code is open source and available on github for you to see that I'm requiring photo/media library permissions actually.

Just to put an update here, new version removed few of these random permissions :)
