Xiaomi is testing the latest Redmi Note 11T Pro and Redmi Note 11T Pro+ alongside the beta version of Android 13 for the Redmi K50. The company itself did not make this event public, but the source, who published details about Xiaomi smartphones, found the appropriate assembly of the operating system.
These three models were created on June 22, 2016 based on Android 13. The build is internal and so far there is no indication that these models will be included in the public beta testing program Android 13, which includes Xiaomi 12, Xiaomi 12 Pro. , Redmi K50 Pro and Xiaomi Pad 5. It seems that the release of the beta version of Android 13 for the three new models is part of the internal routine process of releasing new software versions.
This means that the Redmi K50, Redmi Note 11T Pro, and Redmi Note 11T Pro+ will get Android 13 with first-wave devices, but those who join the open beta testing program will get it later. Android 13 for the first wave of Xiaomi and Redmi devices is expected to be released in October-November this year. Source
