i don’t have the 0.5 zoom anymore??

so randomly one day, it said i had a camera error. something along the lines that my camera might be foreign 🤦🏻‍♀️ eventually the error went away.

but now, every time i open the camera app, its automatically defaulted to 2x. i can’t go to 0.5 wide lens, only on snapchat.

how do i fix it?
