POCO X3 The Pro is one of Xiaomiโs most popular smartphones with great price-performance ratios, but many owners still donโt know how to effectively use the built-in Mi Share feature to transfer files between devices. Unlike classic Bluetooth or instant messengers, this tool allows you to exchange data at speeds up to 10 MB / s โ but only if you are configured correctly.
In this article, we will discuss what Mi Share is. POCO X3 Pro, how it works at the protocol level, what the limitations of the technology are, and how to get around common file transfer errors, and compare it to alternatives like Google's Nearby Share, and find out why the speed sometimes drops to the lower end of the spectrum. 1-2 MB/s - and how to fix it.
What is Mi Share and how does it work? POCO X3 Pro
Mi Share is Xiaomi's proprietary technology for wireless file transfer between devices, developed on the basis of the Wi-Fi Direct protocol.

- ๐ถ Hotspot: If Wi-Fi Direct is not available (e.g. on older models), one device gives away the network and the other connects to it.
- ๐ Encryption: Data is transmitted over a secure dynamic key channel (as opposed to open networks) FTP).
Nana POCO X3 Pro function supports the transfer of files sized 10 GB (in theory), but in practice, the limitations depend on the version MIUI. For example, in firmware older MIUI 12.5 limit increased 20 GB for video and archives. Transmission speeds vary from 2-3 MB/s (at a weak signal) to 8-10 MB/s under ideal conditions.

- ๐ก๏ธ Solution: In Mi Share settings, set visibility to Contact Only or Hidden.
2. Traffic interception
- ๐ต๏ธ Theoretically, using Wi-Fi Direct, an attacker could intercept the metadata of the transmission (e.g., file names).
- ๐ Solution: For confidential files, use password archiving (.zip with a file file) AES-256) beforehand.
3. Local data leakage
- ๐ฑ When you first connect, Mi Share requests access to storage and contacts.Some apps may abuse these permissions.
- ๐ง Solution: Check the permissions in Settings โ Annexes โ Mi Share โ Permits and disable unnecessary.
