Earlier it was said that next Galaxy flagship device will move out of plastic casing since the users felt the build was cheap compared to flagship phones from HTC.
It was speculated that the Galaxy S5 will come with metal casing but later it was decided it would be dropped "to manage the phone's weight."
Now Sam Mobile reports that the Galaxy Series F could be making an appearance with the metal casing idea.
The first phone (SM-G900F) from the F series is said to have a metal casing and it will be a higher end variant of Galaxy S5 with a Quad HD 2K display (2,560×1,600) resolution.
The F series will be released a few weeks after the initial S5 release with both phones expected to be announced on the same day.
