[Update: A new version of this phone has been launched. Check out our Oppo A57 review.]
At under $350 the F1s is a steal. It has features we'd like to see on top-end phones like fast fingerprint unlocking, free case and a three day battery life. Just beware of the camera performance and processing delay with power apps.
Cheap; Good free case; 3-day battery; Fast fingerprint unlock; Looks good and well built; Strong vibrator;
Camera can be slow and noisy; Video performance is poor; Slow processing shows in power apps;
