3. Verification of hardware components
If the software methods didn't work, the problem could be a physical malfunction: the NFC module on the Xiaomi 9T is located next to the wireless charging coil (although the phone itself doesn't support it), and can fail if you have mechanical damage.
- 🔍 External inspection: inspect the back cover of the phone for cracks or dents in the top (where it is located) NFC-Even a small damage can disrupt the operation of the module.
