S4 was a beast, would have kept using it if not for the bootloader lock, android 5.0 is showing its age

This makes sense, the best selling galaxy is the S4 at 80 mln, which brought a better screen and same size for a larger display, then the S5 was bulky and ugly, the s6 was prettier but lacked microsd and other features. Then the S7 brought back microsd and offered the best camera, still on the best around and virtually on par with s8 and s9... Maybe this shows people aren't buying the marketing of those useless curved screen that only make the phone more fragile...
