Mi Share on Redmi Note 9 Pro: The Complete Guide to Setup

Xiaomi smartphone owners often face the need to quickly transfer bulk files to other devices. Standard methods like Bluetooth can seem too slow, and the use of instant messengers often compresses image quality. It is to solve this problem that the MIUI introduced the Mi Share feature, which turns your Redmi Note 9 Pro into a powerful tool for data sharing.

This technology is based on Wi-Fi Direct and Bluetooth protocols, which allows you to achieve high transfer speeds without consuming mobile traffic. You do not need to search for a router or create an access point manually, the system will do everything automatically. In this article, we will discuss in detail how to activate Mi Share, what benefits it provides and how to avoid typical errors when connecting.

Using Android’s built-in tools is often much more effective than installing third-party apps, especially in the Xiaomi ecosystem, where all devices out of the box can understand each other. Let’s take a closer look at how this mechanism works in the Redmi Note 9 Pro model and why this is the best way to share content.

What is Mi Share Technology and How Does It Work?

Mi Share is a proprietary development by Xiaomi that allows instant file transfer between smartphones, tablets and even laptops, and is based on creating a direct wireless connection between devices. Unlike classic Bluetooth, which uses narrow channels, it uses a wider range of Wi-Fi frequencies, which multiplies the speed.

When you send a file, your Redmi Note 9 Pro scans your environment for available devices. Once you find the target gadget, the phones create a temporary secure network. The data is transmitted directly, bypassing servers and cloud storage, which ensures not only high speed, but also the privacy of your personal photos and documents.

It's important to understand the difference between regular Wi-Fi and Wi-Fi Direct, which is the core of the feature. You don't need a router or Internet access. Smartphones become nodes themselves, and this makes transmission possible even in places where there's no cellular coverage or Wi-Fi, such as in the subway or in nature.

💡

Mishare uses Wi-Fi Direct to transmit data at speeds up to 100 Mbps, which is ten times faster than conventional Bluetooth.

It is worth noting that the system intelligently manages energy, the active connection is established only at the time of transmission, and after the process is completed, the module goes into standby mode, which saves battery power Redmi Note 9 Pro while actively using the function during the day.

Device requirements and compatibility

Before you start transferring, you need to make sure that devices are compatible.Mi Share was originally created for Xiaomi, Redmi and POCO devices, on which it works as stable as possible and supports file transfer of any type and size.

But the ecosystem isn’t limited to just one brand: With support for the Oppo Peer-to-Peer Transfer Protocol, you can share files with devices from other vendors like Oppo, Realme and OnePlus, and third-party devices must have a shell version or plug-in app installed.

The feature on the Redmi Note 9 Pro requires a specific version of the operating system, usually MIUI 11 and higher, but for full compatibility with all new encryption protocols, it is better to upgrade to the current version of MIUI 12 or MIUI 13. Older versions of Android may not support the necessary security standards.

• 📱 Full compatibility: All Xiaomi, Redmi smartphones, POCO s MIUI 11+.
• 🤝 Partial compatibility: Oppo, Realme, OnePlus devices (plugin required).
• 💻 Computers: PCs and laptops with Mi Share client installed (official or third-party).
• 🚫 Incompatible: Apple devices (iPhone, iPad) without installing additional intermediary apps.

If you plan to transfer files to your computer, make sure it has a Wi-Fi adapter that supports 802.11ac or higher. Older network cards can become a bottleneck and significantly reduce transfer speeds, despite the capabilities of your Redmi Note 9 Pro.

How to turn Mi Share on Redmi Note 9 Pro

Activation of the function takes only a few seconds and does not require a deep knowledge of technical settings. On the Redmi Note 9 Pro, this option is managed in a convenient notification center, which makes the process intuitive for any user.

To start, unlock your smartphone screen and swipe down from the top edge of the screen to open the control center. In the icon grid, find an icon that says Mi Share. If you don't see it on the first page, swipe left to reveal the full list of available switches.

Once you click on the icon, the system will automatically turn on the necessary communication modules, you will see a pop-up notification that the phone is now visible to other devices, and you can also adjust visibility: make the smartphone visible to everyone or only to contacts from your phone book.

More detailed settings are available through the main menu. Go to Settings → Connection and Sharing → Mi Share. Here you can change the name of the device that will be displayed when you search and adjust the security settings. It is recommended to set a password or file acceptance confirmation to avoid receiving unwanted content.

⚠️ Note: When you turn on the "Visible to all" function, your phone may be detected by strangers in public places, it is recommended to use the "Visible only to contacts" mode or turn off the function after use.

Instructions for file transfer

The file submission process is as simple as possible and integrated into standard gallery and explorer applications. You don’t have to open a separate application to transfer – all actions are performed from the context menu of the file.

Open a gallery or file manager on Redmi Note 9 Pro. Select one or more images, videos or documents you want to submit. Click on the Send icon or select Send via Mi Share from the action menu.

The system will start searching for available devices nearby. Make sure the receiving device also has Mi Share enabled and the screen unlocked. Once the target smartphone appears on the list, tap its name. The receiving party will receive a request for confirmation of acceptance.

Once confirmed, the transfer will start. The screen will display the progress bar and the current speed. The files are saved to the standard MIUI/mishare folder or to the gallery, depending on the file type and settings of the receiving device.

• 📸 Photo and video: Transmitted in original quality without compression.
• 📄 Documents: Formats supported PDF, DOC, XLS others.
• 📱 Contact: You can quickly throw the business card of contact.
• 📍 Geolocation: Sending location coordinates in one click.

The thing about big files is that you can keep the connection stable, and if you go too far in the process, it stops, but unlike Bluetooth, Mi Share often allows you to restart the download from the cliff if you quickly restore the connection.

Speed comparison and technical specifications

Understanding the technical constraints will help you plan your data transfer more efficiently. Mi Share speed depends on many factors: the version of the Wi-Fi module, air interference and the characteristics of the receiving device.

In ideal conditions, both devices support the standard. 802.11ac and are in close proximity, the speed can reach 20-30 MB/s and up, so you can get a movie that weighs a lot. 1 GB in less than a minute. By comparison, Bluetooth would do it in less than a minute. 10-15 minute.

Speed is also affected by the frequency band load, so if you're in a crowded area with lots of Wi-Fi networks running, the speed may drop, and in such cases, the system will automatically switch to a less noisy channel, but the latency may increase.

💡

For maximum transmission speeds, keep the devices no more than 1-2 meters apart and avoid metal obstacles between them.

Solution and troubleshooting

Despite the reliability of the technology, users of the Redmi Note 9 Pro may face certain difficulties, most often problems associated with power saving settings or software version conflicts.

If you don't see another device on the list, the first thing to do is check if Bluetooth is on.Mi Share uses Bluetooth for initial handshake and detection, even if the transfer is over Wi-Fi. Also make sure both phones have a screen unlocked.

A common problem is to "hang" transmissions in the standby phase, in which case restarting communication modules will help, turn on and off flight mode (Air mode) on both devices, this will force the network adapters to restart and clear the cache of connections.

⚠️ Note: If the transmission is interrupted 99%, Don't delete the file right away. MIUI/mishare — Often the file is already there, the system just did not have time to update the gallery index.

In rare cases, you may need to reset your network settings. Go to Settings → Connection and Sharing → Reset Wi-Fi, mobile networks and Bluetooth. Note that this action will remove saved passwords from Wi-Fi networks, but often solves the visibility problems of devices.
