OTA Update
The latest MIUI update doesn’t necessarily mean it’s the best. Read the reviews on the 4PDA or XDA Developers websites before installing new software update to Mi MIX 2S polaris. If you downloaded Flash File, Full ROM or the latest OTA Update and encounter problems with your device after installation, please write about it in the comments section, quoting the number of the buggy firmware.
Mi MIX 2S is on the Xiaomi EOS (end-of-support) list. This is analogous to EOL (End of Life) and means that the smartphone is no longer supported. It does not receive software updates and new firmware from Xiaomi, and known security vulnerabilities are not fixed.
Xiaomi releases monthly and quarterly security patch updates for the Xiaomi, Redmi and POCO for 2-3 years after the device goes to market. Monthly and quarterly security updates include Android security patches from Google as well as fixes for specific issues from Xiaomi.
