1. Presentation. Everything is clearly adjusted, there are no assembly-related problems, all materials are of great quality, and holding the item in your hands is enjoyable. If any fingerprints are left on my black matte iPhone, they are not noticeable. Compared to the 6/6S in Space Gray, I think it looks lot more intriguing in this hue.
2. Showcase. The touchscreen on smartphones is, in my opinion, the best. I use the gadget without a film because the oleophobic coating is of good quality, and fingerprints on the screen are hardly noticeable. The image is of good quality; refer to comment (2).
3. Sound. The sound quality of stereo speakers is far better than that of the iPhone 6 and Samsung Galaxy S7 Edge at any volume level. The sound is luscious, voluminous, and basses are there when I use my native EarPods Lighting headphones, which I had to do several times. I give the sound a total of 5 stars.
4. Execution. I'm unable to comment because I don't play games. In general, you can transition between a variety of open applications, browser tabs, and other programs with a lag time of less than 0.5 seconds. No application slows down concurrently. For me personally, this is a sign—5 months of operation without a single slowdown, reboot, or freeze. I rate the 5. Camera as excellent. I think they are amazing for a smartphone, especially for the front camera, which is the most important one. There are a few little noises in low light, but I'm worried that any smartphone will have them. The photos are of excellent quality, and the stabilization when recording video works well. I made no comparisons with other models, but both cameras are perfect for me.
