How to transfer data to a memory card in Xiaomi Redmi 4X: photos, videos and applications

Xiaomi Redmi 4X is still a popular choice due to its price-performance balance, but its built-in memory (16 or 32 GB) often becomes a bottleneck. Users face the need to make room for new applications, photos or system updates, and a microSD card comes to the rescue. However, the transfer of data to it does not always go smoothly: the system may not see the drive, files are lost when moving, and some applications refuse to work with external memory.

In this article, we will discuss all the ways to transfer data to SD-map 4X — standard-tool MIUI We will focus on the nuances of working with applications (not all of them support porting to an external drive), as well as common errors, for example, when a smartphone does not recognize a card after formatting.
