The rear-facing camera (the regular one) on my phone stopped working. Whenever I try and open my basic camera app, my phone freezes and I get a message saying that my camera stopped working. I know the front facing camera is still working because I can access it through snap chat. I have tried accessing my back-facing camera through snap chat and the same error happens. My phone is completely up-to-date. Any help on how to get it working again would be much appreciated.
