Design
- Very good build quality with unibody metal design
- Gorgeous, large display, with an almost edge-to-edge design - easily one of the best in this segment
- Decent fingerprint sensor
- Large size means one-handed operation is out of the question
Software
- The Qiku 360 UI over Android is buggy (with occasional random app crashes), and a bit more complicated than the usual Android UIs
- Incompatible with a few popular Android apps
Performance
- Very good speed/performance, matching up to the other top performers in this price range
Camera
- Excellent camera performance (arguably one of the best in this range), with innovative dual primary camera technology
Audio
- Good call quality
Battery
- Very good battery life with quick charging support
