NFC

In this article, we will look at all the ways to connect NFC to the Mi9 Lite, from basic chip checks to fine-tuning Google Pay to solving common errors like “The device does not support contactless payments.” We will focus on regional restrictions, because in some versions of the smartphone (for example, for the Indian market), the module can be software blocked. If you have already tried to enable NFC through the standard menu and nothing has worked, do not be upset: below you will find alternative methods using the engineering menu and third-party applications.

We warn you that the procedure may vary depending on the version of MIUI (12, 13 or 14) and regional firmware, but don’t worry, we have covered all options, including hidden settings for the global and Chinese versions of the Mi9 Lite.

• 🛠️ Third-party apps: Install a utility from Google Play NFC Check. It will not only confirm the presence of the module, but also show its technical parameters (for example, support). ISO 14443 for payments).

If neither method has confirmed NFC, chances are your version of the Mi9 Lite does not have that chip, in which case it's pointless. But if there is a chip and the function doesn't work, read on.

Method 3: Use of ADB

If NFC is disabled at the system level, you can try to turn it on via ADB:
