The latest MIUI update is not necessarily the best. Before updating MI 1S (mione), read reviews on 4PDA or XDA Developers. If installing a Flash File, full ROM, or the latest OTA update caused issues, please let us know in the comments and mention the version number.

MI 1S is listed under Xiaomi EOS (end-of-support). It is no longer supported and no updates are released.
