Share This Post
The Qualcomm QET4101 component has been a regular part found in several recent Chinese smartphones, which warranted the need to decap a QET4101 sample to confirm whether it was different from the previously QET4100 counterpart. The initial exploratory work confirmed the difference. The part has been found on the Xiaomi Poco X3 NFC (M2007J20CG), Honor X50 (ALI-AN00), Oppo Reno 10 5G (PHW110) and Vivo S17 5G (V2283A) smartphones.
