* Added some sharpness for front camera on "Pixel 2" model setting (gets grainy under bad light conditions)
General tips for the latest versions:
1. If you choose Nexus5 or Nexus6 model, then you should be using auto-config to avoid app crashing. Nexus6 model will only work with Nexus6 configs on rear camera, and will crash with every config (except auto-config) when using front camera with HDR+.
2. If you are using Nexus 6P model, I suggest that you set Nexus 5x, since rear camera photos are the same, but Nexus 5x front camera takes more detailed photos (which are also more grainy under bad light conditions).
