What reviewers say

Tech Advisor and Android Central praise the vivid display, slim light body and dependable battery life, but criticise preinstalled software and limited demanding gaming. Tech Advisor finds everyday use smooth; Android Central reports frequent stutters. Both find daylight photos useful with limitations beyond the main camera. Tech Advisor also criticises harsh speakers at high volume.
