The internal memory of the Xiaomi Redmi Note 7 is crammed to capacity, and the phone slows down and issues warnings about space shortages? This problem is familiar to many owners of budget smartphones with 64 GB or 32 GB of storage. Even if you do not download movies and install dozens of games, the system and applications gradually โeatโ the free space: cache, updates, temporary files and duplicate photos accumulate unnoticed.
In this article โ 7 working methods for cleaning the memory of Redmi Note 7 (firmware MIUI 10โ14 Android-based 9โ11). We will understand how to delete unnecessary files manually, transfer data to the SD-We'll use the map to optimize applications, and even reset the phone to factory settings if other methods don't work.

Please note the โOther Filesโ section, which often hides:
- ๐๏ธ Cache of applications (especially messengers and social networks).
