The assembly of my new matte black iPhone 7 is not on par with the iPhone 6S (Space Gray): The curved edges of the display blend smoothly with the aluminum casing of my iPhone 6S. With iPhone 7, there are sharp edges where the display meets the body. These can be felt with fingers and when handling the phone. It's not a smooth, continuous transition from glass to metal like it is with the iPhone 6S. It's also pointed out here, so my phone is not an isolated incident: To me, this seems like a QC problem with the assembly. Has anyone else noticed this? Otherwise, my iPhone 7 is perfect. Faster than 6S, the display is better, and to my surprise, iPhone 7 feels lighter than 6S!
