Why can't you just pull out? USB-flash drive from Xiaomi

Many users are used to removing flash drives from their computers without first turning them off — and often without consequences. But in the case of Xiaomi smartphones, the risks are higher for three reasons:

• 🔄 Data caching: MIUI It's using a clipboard to speed up file operations, and if you pull out a flash drive while you write to a cache, some of the data may be lost.
• 📱 Background Processes: Applications (such as a gallery or file manager) can scan the drive in the background, even if you don’t see active operations.
• ⚡ Energy Conservation: On Some Firmware USB-The port is disabled when the screen is locked, which can interrupt unfinished operations.

In practice, this means that even if you don't see the record indicator, the system can still work with files, for example, when you copy photos from the gallery, MIUI Gallery first creates thumbnails and then transfers the originals - and it is dangerous to interrupt this process.
