One day you were going about your business on Snapchat and BAM! your front camera isn’t working. What can you do? The first thing to check is your internet connection. If that doesn’t fix the problem first try restarting Snapchat and if that doesn’t work restart your phone. If so far none of these things have fixed the front camera you might want to check if you can update Snapchat. If you can’t update Snapchat or updating Snapchat didn’t fix the problem you can check settings to make sure you give Snapchat camera access. If none of this fixes this you will want to check if others are experiencing the same thing online. This may just be a bug with Snapchat that you will have to wait out like everyone else.
