The transceivers in Xiaomi smartphones are responsible for wireless communication, from transferring files over Bluetooth to contactless payments over NFC and listening to radio without the Internet. However, many users are faced with the fact that these modules are either disabled by default or hidden in the depths of settings. In this article, we will discuss how to properly activate each type of transceiver on different models of Xiaomi, Redmi and POCO, and solve typical problems with their work.
It is important to understand that not all Xiaomi smartphones are equipped with the same modules, FM-Radio is physically absent in most flagship models (e.g. Xiaomi 13 Pro) and NFC It can be blocked in regional firmware, and we'll take a detailed look at how to check if a module is in your device and what to do if it's not in the settings list.
The article will be useful for both beginners and experienced users: here you will find not only basic instructions, but also hidden chips (for example, how to turn on the keyboard). FM-So, you can start with the most popular one, which is the module, and you can set up Bluetooth 5.3 for the minimum power consumption. NFC, It is often ignored, although it provides access to contactless payments, tags and even smart home management.
1. How to enable NFC on Xiaomi: step-by-step instructions
The NFC (Near Field Communication) module in Xiaomi smartphones is used for contactless payments (Google Pay, Mi Pay), tag reading and connection to smart devices, but by default it is turned off โ this is done to save battery life.
- Open Settings and go to Connect and Sharing (or Wireless Networks in older versions of MIUI).
- Tap on point. NFC. If it is not, then your model does not support the technology (see the list of compatible devices below).
- Translate the slider to the "On" position. You can additionally activate the default Payment option if you use contactless cards.
After turning on, check the operation of the module: bring the phone to the payment terminal or NFC-If nothing happens, make sure that:
- ๐ Battery level above 15% (at low charge) NFC may automatically shut down).
- ๐ฑ There is no case with metal inserts on the phone - they screen the signal.
- ๐ You have updated the firmware to the latest version (in older versions). MIUI were bugs with NFC).
Make sure the module is enabled in the settings
Try bringing your phone to the payment terminal.
Check if there are any metal interference (cover, keys)
Update. MIUI up-to-date-->
Attention! On some models (e.g. the Redmi Note 10 Pro for the Indian market), NFC can be blocked software, in which case only flashing to the global version of MIUI or using custom recovery will help.
2. FM-Radio on Xiaomi: how to turn on without the Internet
