What reviewers say

Both reviews praised the compact design, bright OLED and point-and-shoot camera. Notebookcheck found good battery and system performance; TechRadar needed nightly charging and noted longer loading times in demanding apps. Both found the hardware less flexible than rivals with additional cameras or expandable storage.
