These phone is one of the best smartphone in world. These smartphone comes new A11 chips by Samsung. These is first iphone which have OLED display.so the display has high contrast and great colours. These smartphone has 12 mp dual camera one is monochrome hand other has colour. these camera is pretty good performance. The smartphone has wireless charging. Other features is similar to iPhone 8. Only drowback is the price of the device is considerably higher. But the phone has good specs and I recommend the phone for who upgrading from iPhone 6 or 6s.
