The MIUI 12.2.1 update broke some Xiaomi smartphones
It is better to wait with the update. Recall that yesterday the Chinese giant Xiaomi released an update MIUI 22.214.171.124 based on Android 11, which was to give the flagship smartphones Mi 10, Mi 10 Pro and Redmi K30 Pro new camera modes. As a result, the update "broke" some smartphones.
So, in addition to the new camera modes, users have encountered various problems. In particular, the updated smartphones refused to connect to the Internet from the second SIM card. In addition, during charging, the display became insensitive, the frame rate decreased during games, and energy consumption increased.
Users also complained about delays in creating screenshots and heating devices. Due to "breakdowns" of some smartphones due to the update, a publication appeared on the official support site, in which users were not recommended to install MIUI 126.96.36.199.
