Same here when I switched to the bata at first everything worked fine, minus a few freezing apps but then the last bata update came out, and now just my front-facing camera doesn’t work. Then the rear is fine. This just happened I think 2 days ago. It’s very inconvenient, then when I took it to apple. They said they wanted to send my phone in for 5-7 days cause they have no idea what was wrong.
