Xiaomi and Redmi’s current smartphones feature a variety of wireless connectivity modules that make everyday tasks easier. One of the most convenient but often underrated features is NFC (Near Field Communication), which allows data to be exchanged over ultra-small distances, literally touching each other’s devices. For many users, this is a revelation, because the speed and simplicity of the process far outperform traditional methods like Bluetooth or instant messengers.
The main advantage of the technology is that you don't have to create complex pairings or enter passwords. Just put two gadgets on the back. However, to transfer files over NFC worked consistently on devices of the Chinese brand, you need to set up the system correctly. In this article, we will discuss all the nuances of the module, the peculiarities of working with MIUI and HyperOS, and also answer the question why modern smartphones often use NFC only to run other transmission protocols.
One of the most important technical points to note is that the classic NFC protocol has a very low data rate, which is why on Xiaomi smartphones it often acts as a “digital key” that automatically activates a faster communication channel, such as Wi-Fi Direct or the proprietary Mi Share protocol, while the user sees only instant connection and high speed copying photos or videos.
Preparing the device to work with NFC
Before you start sharing data, you need to make sure that the short-range module is activated and functioning correctly. On most Xiaomi and Redmi models, the antenna is located at the top of the case, often next to the camera.
The fastest way to turn on the module is to use the control panel. Swipe from top to bottom across the screen to open the notification curtain. Find the NFC icon and tap it so it lights up in blue. If the icon is not in quick access, it can be found through the basic system settings.
- 📱 Open the Settings app on the main screen.
- 🔍 In the search bar, enter «NFC» or go to the Connection and Sharing section.
- ✅ Activate the slider "Use" NFC».
- 📂 Make sure that Android Beam or Mi Share is chosen as the default file transfer application.
It is important to note that different versions of MIUI firmware may have different menus, and in global versions, settings are often in the Connection and Sharing section, whereas in Chinese builds, this item may be called Wireless Networks. If you can't find the switch, search by settings by entering the acronym for the technology.
⚠️ Warning: Make sure your smartphone case does not contain metal plates or magnets. Metal elements in the case can shield the signal, which will interrupt the data transmission or not start at all.
⚠️ Note: For the function “only when unlocked screen” in the security settings must be set that NFC It works even on a locked device if you plan to use it for payments, but the screen must be active to transfer files.
Set up Android Beam and Mi Share
The key to sharing data is choosing the right software to transfer, long the de facto standard was Android Beam, but Google is gradually abandoning the technology in favor of more modern solutions.
Modern versions of HyperOS and new MIUI prioritize Mi Share (or simply Share), which uses NFC to pair quickly, then switches to Wi-Fi Direct to transfer heavy files, which delivers speeds of up to 100 Mbps, ten times faster than classic Bluetooth.
To set your application priority, go to Settings → Connection and Sharing → NFC. Here you will see “Tap and Pay” or “Default Element.” To transfer files between Android phones, you need the correct handler to be selected in the “File Transfer” (or similar) section.
If you are transferring data to another Xiaomi device, the system itself will suggest using Mi Share. If the receiving device is a smartphone of another brand, you may need to activate Android Beam. Note that in Android 11 and later, this feature can be hidden or removed, so it is better to use universal methods for cross-platform transmission.
Step-by-step instructions for file transfer
The process of transferring data between two smartphones is as simple as possible and designed for intuitive use. However, to avoid errors and breaks in the connection, it is recommended to adhere to a certain algorithm of actions, this is especially true when transferring large amounts of data, such as video to 4K or photo packets.
First, make sure that both devices are unlocked and active. The screens should be on and the devices should be detectable. Come close to each other, the distance between the rear panels should be no more than 2-3 centimeters.
- Open the file you want to send (photo, contact, link in the browser).
- Click the “Share” button (three-dot icon or arrow icon).
- In the list of available ways, choose Android Beam or Mi Share.
- Bring the back of your smartphone to the back of the recipient’s device.
- Wait for vibration or a characteristic audible signal to confirm the connection.
- The screen will show a preview of the file and the “Send” button – click it.
What do I do if the transmission is suspended?
If the transmission process is frozen during the “Waiting” stage, try turning off and re-energize the screen on both devices, and a brief Wi-Fi shutdown on the receiving device also helps to force the system to switch to the protocol. NFC/Bluetooth handshake.> After the successful transfer, a notification of a new file will appear on the screen of the receiving device. If you transmit contacts, they can immediately be added to the phone book. Small text files are transmitted instantly, while video is in the 1 Transfer of data between Xiaomi and other devices Interaction between devices of the same brand usually passes without problems thanks to optimization MIUI. However, when trying to transfer the file to a smartphone Samsung, Huawei or iPhone, you may have difficulties. Different vendors use different exchange protocol implementations, and when it is transferred to other Android smartphones, the system will try to use the standard Android Beam, and if both devices are enabled, the transfer will be successful. Otherwise, the system may suggest installing an additional application or using the QR-Recipient Device Type Probability of Success Recommended Nuances Method Xiaomi/Redmi / POCO High (99%) Mi Share / NFC Automatic switch to Wi-Fi Direct Other Android (Samsung, Sony) Average (70%) Android Beam Depends on Android version and availability of Google iPhone (iOS) Services Low (10%) Unsupported iOS blocks file reception via NFC from Android Laptop with NFC Low Special. software Requires installed software for synchronization With Apple devices, the situation is more complicated.

If the classic method by touch doesn’t work or seems uncomfortable to you, the Xiaomi ecosystem offers a number of alternatives. They are often even more effective, especially when working with large files or when transferring data to devices that do not support them. NFC. One of the best solutions is the Mi Drop feature, which is integrated into Mi Share, which creates a local Wi-Fi hotspot that other devices can connect to, and it's up to tens of megabytes per second, allowing you to stream a movie in a couple of seconds. 🚀 Mi Share: Works similarly to Apple's AirDrop. Allows you to transfer files without the Internet using Wi-Fi and Bluetooth. 🌐 Quick Share (Google): Google’s universal standard, now supported on Xiaomi, allows you to see nearby devices in the notification curtain. ☁️ Xiaomi Cloud / Google Photos: Automatic synchronization allows you to access files on any device where you log in to your account.

Why is it very slow when files are small? Most likely, the connection did not switch to a high-speed protocol (Wi-Fi Direct) and goes through the classic Bluetooth or the channel itself. NFC, The speed is extremely low, and make sure that both devices are Bluetooth and Wi-Fi enabled, because NFC It's often used only for handshakes, and the data goes through a different channel. Does the file transfer work if the phone's screen goes out? Most of the time, it doesn't. NFC On smartphones, Xiaomi goes into sleep mode when the screen is off. To initiate the transfer, the screens of both devices must be on and, preferably, unlocked. NFC In public places? Yes, it's safe. Technology. NFC It works at a distance of several centimeters. It is physically impossible to intercept the signal on the fly, since the attacker would have to practically attach his device to your device, and user confirmation on both devices is required to start transmission. 💡NFC Xiaomi is a handy tool for instant transfer of small files and contacts, but for large amounts of data, the system automatically (or manually) switches to faster Wi-Fi Direct protocols, ensuring high speed and stability of the connection.
