Mi Share on Xiaomi Redmi Note 8 Pro: a complete guide to wireless file transfer

If you own Xiaomi Redmi Note 8 Pro, you probably noticed in the quick settings menu a mysterious item Mi Share — proprietary technology wireless file sharing from Xiaomi. At first glance, this is another analogue of AirDrop or Nearby Share, but with nuances that make it unique to the MIUI ecosystem. In this article, we will analyze how Mi Share works on your smartphone, why it sometimes refuses to transfer files, and what can be replaced if the speed leaves much to be desired.

It’s worth clarifying: Mi Share is not just a Chinese AirDrop. The technology uses a combination of Wi-Fi Direct and Bluetooth LE to establish a connection, which should theoretically provide high transfer speeds (up to 10 MB/s in ideal conditions). However, in practice, Redmi Note 8 Pro users often face limitations, from incompatibility with other brands to sudden communication breakdowns.

What is Mi Share and how does it work on the Redmi Note 8 Pro?

Mi Share is a wireless file transfer protocol developed by Xiaomi for MIUI-based devices. Unlike classic Bluetooth, which is limited to 1-2 MB/s, it uses Wi-Fi Direct (point-to-point), which allows you to transfer photos, videos and documents much faster, while Bluetooth LE is used only for connection - further data exchange goes over a high-speed channel.

On the Redmi Note 8 Pro, the feature is available out of the box and does not require additional applications. It is important to understand that Mi Share is optimized primarily for Xiaomi, Redmi and POCO devices. With other brands (for example, Samsung or Huawei), compatibility is limited - sometimes files are transferred, but with errors or low speeds. This is due to the proprietary protocols of each manufacturer.

• 🔄 Two-way transfer: You can send and receive files at the same time.
• 📶 Automatic switching: if Wi-Fi is busy, the mobile network is used (but this slows down the process).
• 🔒 Encryption: Data is transmitted with security, but not at the AirDrop level (no end-to-end encryption).
• 📱 Size limit: theoretically up to 1 GB per session, but in practice, stability drops after 500 MB.

A critical feature for the Redmi Note 8 Pro: Mi Share only works on MIUI 11 and later. If your device is stuck on MIUI 10 (for example, due to regional firmware), update the software via Settings → About Phone → System Update.

How to Enable and Configure Mi Share on Redmi Note 8 Pro

You can activate Mi Share in two ways: through the Quick Settings Panel or the Settings menu.

1. Through the notification curtain: Swipe down from the top of the screen to open the Quick Settings panel. Find the Mi Share icon. If it's not there, click on the button"⚙️ Edit" and add to active elements. tap on the icon to enable visibility for other devices.
2. Through Settings: Go to Settings → Connections and Sharing → Mi Share. Activate the Mi Share switch. Set up the Device Name (default is the smartphone model) and Visibility Mode (Contacts Only or All).

Once activated, your Redmi Note 8 Pro will be visible to other Mi Share devices within a radius of ~10 meters.

Select a file in the gallery/file manager|Press "Share" →"Mi Share"|Select the target device from the list|Confirm reception on the second phone-->

⚠️ Note: If you have a “Disconnected” error when transferring files, make sure that both devices are enabled with Wi-Fi and Bluetooth. Also make sure that the receiving phone has “All” visibility in the Mi Share settings (if you are sending from an unfamiliar device).

Transfer speed and real tests on the Redmi Note 8 Pro

The theoretical speed of the Mi Share is 10MB/s, but in practice it depends on the conditions. We ran tests on the Redmi Note 8 Pro (MIUI 14) with different file types:

The tests show that Mi Share is effective for small files (photos, documents), but loses stability when transferring large data. For example, 4K videos or archives over 500 MB are often transmitted with errors or require resending, due to the limitations of Wi-Fi Direct on the Redmi Note 8 Pro, which uses the Mediatek Helio G90T chip, which is not optimized for long high-load sessions.

⚠️ Warning: If the transfer rate drops below 1MB/s, try to disable Mobile data on both devices. Sometimes background network activity prevents Wi-Fi Direct from establishing a stable connection.

Limitations and Typical Mi Share Problems on the Redmi Note 8 Pro

Despite the convenience, the Mi Share is not without its drawbacks, and here are the most common problems and their causes:

• 🚫 Unable to find the device: most often due to the fact that one of the phones is turned off Bluetooth or Wi-Fi. Also check whether the transmission is blocked by Power Saving Mode (it can turn off background processes).
• ⏳ Connection: This occurs if the devices are too far away (more than 5 meters) or there are physical barriers (walls, furniture) between them).
• 🔄 Transfer Breakdown: Typical for Files > 500MB solution: Break the archive into pieces or use a cable.
• 📱 Incompatibility with other brands: Mi Share doesn't work well with Samsung Quick Share or Huawei Share.For cross-platform transfer, it's better to use Nearby Share (Google).

Another common complaint is that Mi Share eats up battery power, which is because both Wi-Fi and Bluetooth are used in the transmission. On the Redmi Note 8 Pro with a 4500 mAh battery, one 1 GB file transfer session can reduce charge by 5-7%.

Mi Share Alternatives: What to Use When It Doesn't Work

If Mi Share is not up to the task, consider alternative ways to transfer files:

💡

If you need to regularly transfer large files between Xiaomi devices, consider using Xiaomi Local Network (in Settings → Connections and Sharing).This method works via a router and is more stable than Wi-Fi Direct, especially for 4K video.

For owners of Redmi Note 8 Pro, the best choice depends on the task:

• 📸 Photo/documents → Mi Share or Nearby Share.
• 🎥 Video 4K/archive → Cable OTG or the Local Network.
• 🌍 Transfer to iPhone/Mac → AirDrop (through emulators inconvenient).

How to Fix Mi Share Errors: A Step-by-Step Guide

If Mi Share refuses to work, follow this algorithm:

1. Check basic settings: Make sure Wi-Fi and Bluetooth are on both devices. Turn off Flight Mode and Energy Saving. Check that the receiving phone has All Visibility Mode in Settings → Mi Share.

Reset the devices:

Sometimes background processes block Wi-Fi Direct, and a simple reboot helps 60 percent of the time.

Update MIUI:

On the Redmi Note 8 Pro, Mi Share runs on MIUI 12.5+. Check the updates in Settings → About Phone → System Update.

Reset the network settings:

Go to Settings → Wi-Fi → Additional → Network Reset. This will remove saved networks, but often solves problems with Wi-Fi Direct.

Check the regional firmware:

On some global firmware, Mi Share is disabled by default. If you have an EEA or RU version, try switching to Global via Fastboot.

💡

If neither of these methods worked, try using Xiaomi Local Network instead of Mi Share, a method that is less prone to failure, as it uses the router as an intermediary rather than a direct connection.

⚠️ Note: On the Redmi Note 8 Pro with custom firmware (like LineageOS), the Mi Share may not work at all due to the lack of proprietary Xiaomi drivers. KDE Connect will be more reliable.

Mi Share Security: How Secure is Data Transfer

Mi Share uses encryption when transferring files, but its level of protection is inferior to those of Apple or Google.

• 🔐 Encryption: data is transmitted in encrypted form, but the algorithm is not disclosed by Xiaomi. AES-128.
• 👥 Authentication: Manual consent is required on the receiving device to confirm the transfer (proof against accidental sending).
• 📡 Vulnerabilities: Wi-Fi Direct bugs were discovered in 2022 to intercept traffic. Xiaomi released patches, but the risk remains for outdated firmware.
• 📱 Privacy: Mi Share does not collect file metadata (unlike cloud services), but the device name and model are visible to other users within range.

For sensitive data transfer (e.g., document scans), it is better to use:

• 🔒 Encrypted archives (with a password) before being sent via Mi Share.
• 📁 Local area network on WPA3 router.
• 🌐 Cloud with E2E-Encryption (e.g. Proton Drive).
