I had these questions with the S20 FE. The only thing it had that I'd wanted really was the SD card slot. Looking into it after I'd gotten it, turned out the reason I was always missing calls was that the ringtone at max volume was so quiet I couldn't hear it from my coat's breast pocket. Like...the media played on the speakers was loud enough for me to hear clearly from my trouser's front pocket...so why the fuck was the ringtone so goddamn quiet?!?
