The Samsung Galaxy C9 Pro is full of innovative and inspiring features: the customizable large six-inch always-on display (AOD) shows information and messages on the display without turning off while saving battery life. Two 16-megapixel cameras on the front and back sides take vivid and sharp images. The rear camera in “Pro Mode” can be manually adjusted like a professional SLR camera. The 16-megapixel front camera can take selfie images, and can be adjusted with automatic beautify features. The entire antenna system is substituted and built inside the metal body with three 0.4 mm line MSA (Micro Slit Antenna). The three subtle lines make for a unique differentiation.
