What reviewers say
Expert Reviews and TechRadar praise the large bright screen, comfortable design, capable performance and battery life. Expert Reviews finds the launch upgrade modest and HyperOS frustrating; TechRadar is more positive about value and customisation after later software updates and price reductions. Both find the cameras useful, although TechRadar considers the telephoto reach limited.
