After announcing the arrival of the MIUI 9 OS on 4o new devices, Xiaomi has started rolling out a new version of its user interface on some of its latest smartphones: MIUI 9.2. Considering that it is not a major update, there are just a few changes and improvements than the original v9, but it is worth noting that some very interesting features have been implemented. The MIUI 9.2 will only roll out to devices which has already received the update to the v9 Global Stable ROM. Other devices will have to wait for this release until they get their Global Stable update.
According to the changelog, MIUI 9.2 brings the App Vault feature, a new Gallery editor, and the Mi Video app. Further, there is a fix for the KRACK WPA2 security vulnerabilities and a fix for the dual notification bug spotted in WhatsApp and Telegram in the previous version of the firmware. The UI has been simplified and now the Mi Mover app supports data migration restart. This means that if you are migrating your data from a phone to another and the hotspot connection accidentally interrupts, it will be restored automatically and it will continue from the same point. The update also adds dynamic calibration function for the distance sensor, which will enable the screen to turn off and on correctly when needed.
There are also some fixes for the fingerprint reader and some compatibility issues with third-party software on full-screen devices. Other minor optimizations in MIUI 9.2 include home screen, themes, the App Lock, the Backup function and the Mi Account. The update has been rolled out in its Stable version on the Xiaomi Mi Mix 2, Xiaomi Redmi Note 4, Xiaomi Redmi 4, Xiaomi Redmi Y1, Xiaomi Redmi Y1 Lite and Xiaomi Redmi 5A. Unfortunately, we do not know when the update will hit the other devices of the company.
