iphone 7 camera not working - black screen
I got my iPhone 7 two days ago and tried the camera once and it worked. I remember hitting the "live" feature on the camera app and it force closing. I left it alone for a while and when I tried it today nothing was happening. I get a black screen on the back camera and picture on the front facing. Apps that use the camera also do not register a back facing camera picture. I have reset/restored my phone to no avail.
Any help on this would be great. I'll go into sprint tomorrow and I don't foresee why they wouldn't fix/replace it being only 2 days in my possession.
iPhone 7, iOS 10.0.2
