Budget smartphone owners often wonder about the availability and activation of a short-range module in their device. Xiaomi’s Redmi 4X became a bestseller thanks to its combination of price and performance. However, the functionality of wireless interfaces in the budget segment has always been a subject of controversy and refinement.
Before looking for settings in the menu, you need to firmly learn one critical fact: the Xiaomi Redmi 4X (model codes 2016121, 2016122) does not have an NFC module in any of the official versions, which means that standard methods to enable this feature on this device is impossible, since the corresponding chip and antenna are physically missing.
However, many users continue to search for activation methods, confusing this model with more expensive siblings or modified versions. In this article, we will discuss in detail the specifications of the device, explain the reasons for the lack of the module, and consider real alternatives for contactless payment and data transfer that are available to owners of this gadget.
Technical specifications and lack of module
To understand the situation, you need to refer to the official specification of the device. 4X It is based on Qualcomm's Snapdragon 435 processor. Although the chipset theoretically supports short-range communication modules, Xiaomi engineers decided not to include the chip. NFC-Controller in the final assembly to reduce the cost.
The lack of a chip is confirmed by the absence of a corresponding item in the system menu “Quick Settings” and the section “Wireless Networks”. Even with the installation of third-party launchers or modified firmware, the software shell will not be able to activate non-existent hardware. This is a fundamental limitation of “hardware”.
Why did the NFC get removed from the public sector?
It is worth noting that the absence NFC Wi-Fi and Bluetooth 4.2, which are present in the device, fully cover the needs for file transfer and peripheral connection. GPS, which works regardless of the availability of a short-range communication module.
How to Check for NFC on Any Android
If you have purchased a device from hand or use custom firmware and you have doubts about the configuration, there are proven methods of diagnosis.
The fastest way is to use the search bar in your system settings, type the word "NFC" or "Contactless" in the Android settings search box. If the module is present, the system will give the corresponding menu item to activate it. If the search does not find anything, the module is not.
☑️ Verification of availability NFC
You can also use specialised apps from the Google Play Store, such as: AIDA64 or Device Info HW. These ulites provide comprehensive information about all sensors and controllers installed in the phone. NFC controller.
Also note the back cover of the device. Official contactless smartphones often have the NFC logo at the bottom of the case. The Redmi 4X doesn't have one, another visual confirmation of its absence.
Alternatives for contactless payment
Despite the lack of a built-in module, Xiaomi owners can use contactless payment services. The accessories market offers solutions that bypass the hardware limitation of a smartphone, allowing you to pay for purchases in terminals.
One of the popular solutions is NFC-These are wearables that sync with a credit card or contain a chip with a virtual account, and you just put your hand in the terminal, and the payment goes through.
- 💳 NFC-rings: Stylish accessory that is worn on the finger and emulates the card.
- ⌚ Smart bracelets: Some fitness trackers from Xiaomi and other brands support payment feature (Mi Band with Xiaomi) NFC, Compatibility with the region is required).
- 🏷️ Label stickers: Special stickers from banks that are glued to a regular plastic card or to the back cover of the phone (if it is not metal, which is relevant for the user). 4X).
It's important to consider the material of the case. Redmi 4X has a metal back panel. Metal shields the signal, so you can't glue bank stickers directly onto the case -- the terminal doesn't count them. Use a case or wear a tag separately.
Bluetooth and Wi-Fi settings for data transfer
Since the Android Beam feature, which worked over NFC to transfer files, is not available on this device, Bluetooth becomes the main communication channel.
Go to Settings → Bluetooth. Make sure the switch is activated. To improve security, it is recommended to set the Visibility setting “See for All” only for the duration of file transfer, then hide the device.
💡
Use the Mi Drop app (now Mi Share) to transfer large files between Xiaomi smartphones.It works over Wi-Fi Direct and transmits data at times faster than classic Bluetooth.
For transferring large files such as videos or photo archives, it is better to use a direct Wi-Fi connection or cloud services. Xiaomi's built-in file manager has a "Clean up" and "Transfer" feature that allows you to send files over the Internet. QR-code without Internet traffic consumption.
Keep in mind that constantly searching for Bluetooth devices can consume battery power. Once the data session is over, it is recommended to turn off the module or put the phone into flight mode if the network is not needed.
Comparison with other Xiaomi models
To understand the Redmi 4X’s place in the lineup, it’s useful to compare its performance with other popular models from the same period, which will help you assess which features were a victim of cost savings and which became the standard.
| Model | NFC | Processor | Case material |
|---|---|---|---|
| Redmi 4X | No. | Snapdragon 435 | Metal |
| Redmi Note 4X | No (in the global) | Snapdragon 625 | Metal |
| Mi 6 | There is. | Snapdragon 835 | Glass/Metal |
| Redmi 5 Plus | No. | Snapdragon 625 | Metal |
As you can see from the table, even the more powerful Redmi series models have long been deprived of the NFC module. The flagship Mi series has always been equipped with a full set of wireless interfaces, which began to change only with the release of the Redmi Note 8 series and later, where NFC began to be massively introduced.
If contactless payment is critical for you, when choosing a device, you should pay attention to models released no earlier than 2019-2020, or immediately look towards the middle and upper price segment. Budget employees of the time (2016-2017) almost universally did not have this module.
Frequent questions and myths about firmware
There are claims online that installing Chinese firmware or using special patches can unlock NFC on Redmi 4X.
Attempts to insert drivers of non-existent hardware into the kernel of the system will only lead to compilation errors, cyclic reboots, or complete failure of communication modules (Wi-Fi/Bluetooth), since they can use the common resources of the bus.
⚠️ Note: Installation of modified system files for activation NFC On devices without the appropriate hardware, the radio module may be disrupted. Recovery will require reflashing the stock image via Fastboot.
The only scenario where NFC can come out of nowhere is if you bought a device that is a re-labeled clone or more expensive model, but these are extremely rare cases that are not relevant to standard Redmi 4X operation.
In conclusion, Xiaomi Redmi 4X owners should accept the lack of a neighbor and use alternative methods of payment and data transfer. The device remains a reliable assistant due to the stable operation of basic functions and excellent autonomy.
