Metal body for Samsung Galaxy S4 would have meant delay
metal body to its construction, the bottom line is that this would have delayed shipping the device. Not wanting to hold off launching its next flagship model, Samsung decided to continue to use the S.O.P (Same Old Plastic) on the phone.
What is interesting is the report that for the Samsung GALAXY Note III, the phablet will be made of something other than the lightweight plastic that has now come to be associated with the manufacturer. Until we see it, we will have to take this speculation with the proverbial grain of salt. Still, it is something for Samsung fans to look forward to because if it works on the GALAXY Note III, the new sturdier design should find its way onto the Samsung Galaxy S5. Samsung is said to be concerned with how its phones stack up in the looks department, so expect a focus there in the next year.
