Camera:
My full frame camera is Sony A7r2. And I use Galaxy Note 7 as my daily "camera". The picture quality is stunning. You can fully control ISO, shutter speed (10s), color temperature. You can also do raw editing using snapseed.

P.S.1 when you apply color tone in camera pro mode, raw pic. cannot be saved
P.S.2 raw pic. cannot be saved on sd card, but internal storage only. Stupid note 7
