What reviewers say

Tech Advisor and TechRadar praise the long battery life, quick charging, smooth gaming, bright screen and sturdy build. Both find the main camera adequate but the ultrawide weak, miss a separate zoom camera and criticise the preinstalled software. Tech Advisor enjoys the camera-ring lighting more than TechRadar, which finds it of limited everyday use. Both see the size and weight as a compromise for the large screen and battery.
