Samsung m20 and Samsung a30 has same hardware. Same chipset. But they run completely different operating systems. A30 has completed one ui and m20 run some kind of basic featured android system. Samsung galaxy a30 have Bixby, Knox, Samsung Good lock app, and other one ui features. But Samsung m20 doesn't have Bixby, knox and Doesn't even compatible with Good Lock. While Samsung m20 and a30 has same hardware why can't Samsung give to their own customers to satisfaction. We don't want some kind of limited functions optimised operating system crap.
