I have a Galaxy S7 edge Model Number SM-G935F originally supplied to Orange France that had specific firmware that does not allow WIFI Calling and I want to know if it is possible to re flash the phone to Samsung original standard which is advertised to support this functionr
You can, I done it to my Tab S4, but its not for the faint hearted, you risk permanently breaking your device. And even if successful, you will lose, Samsung Pay and Secure folder.
