What reviewers say

Expert Reviews and Tech Advisor praise the sharp displays, strong rear cameras, fast performance and intuitive multitasking. Both criticise limited water protection and absent wireless charging. Expert Reviews finds everyday endurance strong with occasional inner-screen use; Tech Advisor finds heavy use can struggle to last a day and some apps poorly adapted to the larger screen.
