Design
- Good build quality
- Soft-touch coating makes the handset feel nicely grippable and smooth, and has the added benefit of deflecting smudges
- A bit bulky
Display
- Large and vivid 5-inch display
Software
- Default launcher (interface) is not as easy-to-use, or intuitive as standard Android
- No Google Play store, and constrained app ecosystem - since the phone uses a fork of the Android codebase, and not the standard Google supported version, apps which tie into Google's push notifications, in-app payments and maps APIs, for instance, are either unavailable or won't function properly
- Limited internal memory could become an issue if you install a large number of apps/games
Performance

Camera
- Good camera
Audio
- Good call quality
Battery

More
