SD-But in Redmi. 8T firmware MIUI This process has its own nuances: not all applications support transfer, and some after moving may work unstablely.

In this article, we will look at all the available methods, from standard Android settings to developer and third-party utilities, which applications can be transferred without risk and which are better left in internal memory, and we will also tell you how to format the memory card correctly to avoid errors, and what to do if after transferring programs stop running.

Important: the instructions are relevant for Redmi 8T based on MIUI 11/12 and Android 9/10. On newer versions of firmware, some menu items may differ, but the general logic remains the same.
