My Droid Turbo 2's camera won't flip to the front-facing side. How can I fix this??

[AC Question]

I have completely no idea how to fix it and I don't want to uninstall the camera because I don't wanna lose all my pictures. Anyone know how to fix this problem?

installing a new camera app won't delete the photos, but is it actually the camera app that causes the issue?
