Xiaomi released an internal update about the Pad 5 series, most likely regarding the release of Android 12. We have an official quote from Xiaomi about the situation, which is as follows;
Due to the major version upgrade of Android, Xiaomi Mi Pad 5 Pro 5G, Mi Pad 5 Pro, Mi Pad 5 will suspend the internal beta release from February 7, 2022. Thank you for your understanding.
The updates following 22.1.7 China have been suspended, due to Android 12’s release and the next update to the Pad 5 series will most likely be a major platform update, Android 12.
The Pad 5 series was released out of the box with MIUI 12.5, based on Android 11, and recently received MIUI 13, still based on Android 11 globally. We would’ve loved it if the new update was be based on Android 12L so that the users can use the device to its fullest potential with 12L’s tablet-focused and big-screen features and optimizations. Unfortunately, it will be based on regular Android 12.
