Fingerprint sensor, face unlock security,front camera, 6.19 inch display with high quality specially color of device ( blue lagoon) makes it perfect from any other device but rear camera not so good as i think. And notification does not show when you are using a device, this is a very big problem. You,ve to slide down to check your notification. Other problem is that you can,t see your battery percentage at your homescreen. You have no idea how much percentage is left.
