I use a generic unbranded one that came with a chinese tablet and it works fine with my Galaxy S7.
---------------------------
Same with me. I used the charging cable that came with my Xiaomi Mi9, with the USB C connector connected to the NanoVNA, and the USB A connector connected to this adapter bought on Amazon (sorry, I do not have anymore the URL...). Worked at the first try. Android version is 9.
