Why does NFC card reading fail after wireless charging on the Xiaomi 17 Ultra with a Kevlar case?
If NFC card reading fails after wireless charging when using a Kevlar case on the Xiaomi 17 Ultra, please refer to the following explanation:
1. The Kevlar case has a relatively thicker structure. Its material and thickness can partially overlap with the phone’s NFC sensing area, which can affect signal transmission efficiency.
2. After wireless charging, residual electromagnetic interference or slight temperature rise around the NFC module can temporarily influence NFC signal stability, especially when combined with the added thickness of the case.
3. If NFC reading fails, please turn NFC off and then on again in Settings to reinitialize the NFC module.
