What Files Can Be Transferred Through Mi Share and Its Limitations

Mi Share on Redmi 9 supports most popular formats, but there are nuances with file sizes and types.

It is important to note that:

• 🚫 System files are not supported (e.g. backups.nb0 firmware).
• ⏳ Speed depends on the distance: at 1-2 meters - up to 15 MB / s, at 10 meters - falls to 2-5 MB / s.
• 🔋 Battery consumption: when transferring large files, Redmi 9 can discharge by 1-2% per minute.

Mi Share Alternatives for Redmi 9: What to Use if It Doesn't Work

If Mi Share refuses to work or you need to send files to a device other than Xiaomi, consider these options:

1. Nearby Share (Google)

AirDrop for Android, works on all Android 6.0 devices+. Speed is lower (up to 5-8 MB / s), but more reliable in the conditions of interference.

• ✅ Pros: cross-platform, stability.
• ❌ Cons: requires Google Play Services, sometimes “loses” devices.

2. Snapdrop (web service)

It works through a browser over a local network, which is a great option if you need to transfer files to a PC or iPhone.

• ✅ Pros: no need to install applications, works on any device.
• ❌ Cons: speed depends on the router, the maximum file size is 2 GB.

3. Bluetooth (classic)

Slowly (1-2 MB/s), but universally suitable for small files (contacts, low-resolution photos).

4.Local. FTP-server (e.g. Solid Explorer)

For advanced users: you can deploy FTP-server on Redmi 9 and connect to it from another device via Wi-Fi.

• ✅ Pros: high speed (up to 20 MB / s), support for large files.
• ❌ Cons: requires customization, inconvenient for beginners.

For Redmi 9, the best choice depends on the task:

• 📱 Xiaomi → Xiaomi: Mi Share (the fastest option).
• 📱 Xiaomi → Android: Nearby Share.
• 💻 Xiaomi → PC/Mac/iPhone: snapdrop or FTP.

Mi Share Security: How Secure is Data Transfer

Mi Share uses encryption when transferring files, but there are a few nuances to be aware of:

✅ Security benefits:

• 🔐 Data is transmitted in encrypted form (AES-128).
• 👥 Confirmation on both devices: without user permission, the file will not be sent.
• 📡 Local area network: files do not pass through Xiaomi servers (unlike cloud services).

⚠️ Risks and limitations:

⚠️ Note: If you are transferring files in a public place (such as a cafe or airport), an attacker could theoretically intercept traffic by connecting to the same Wi-Fi Direct network. To minimize risk, disable Mi Share after transfer and do not use it for sensitive documents (passports, bank details).

Comparison with alternatives:

• 🔒 Nearby Share: Uses encryption, but data passes through Google servers for a short time.
• 🌐 Snapdrop: Transfers are direct, but without encryption (risk when used on public networks).
• 📶 FTP: Protection depends on settings (it is recommended to include password authorization).

If you need to transfer sensitive data (such as scans of documents), it is better to:

1. Archive files with a password (for example, in.zip with a file) AES-256).
2. Use Nearby Share or Snapdrop on a trusted network.
3. After transfer, delete files from the MiShare folder on both devices.
