Owners of Xiaomi Redmi Note 9T and other models based on MIUI Often face a lack of internal memory — especially if the phone is purchased with a minimum volume (64 GB or 128 GB). Even after cleaning the cache and removing unnecessary files, the system can show a warning about overflowing storage. SD-The map seems to be a logical solution, but in MIUI This feature doesn’t work as clearly as it does in “pure” Android.
