I don't know why Samsung puts two different sensors into their phones. Mine (S7) has the Sony sensor in it (I'm in Pennsylvania). How do they pick and choose? Which one is better? Any idea why they do this?
Get the app AIDA64 https://play.google.com/store/apps/details?id=com.finalwire.aida64&hl=en This app will give you a full report. You will need to give AIDA64 the permission to use camera. Settings>Applications>Application Manager>AIDA64 and there in permissions, ok camera. After you give permissions, restart your S7 and then open AIDA64 for your full report.
