The report also mentions that the Galaxy S5
is a name open to change .Already Samsung has started releasing phones
bearing single alphabets as their model names, Galaxy J as an example.
In the future we can expect the name S5 to change.( Interestingly
reversing it makes 5S, the name of the Apple iPhone 5S).

The Galaxy S5 has had a good round of rumors, from the metal body
hype to the somewhat absurd iris sensor. Expect Samsung to miss the
Galaxy S5 launch at CES which is due next week. Samsung may instead treat you with it’s Galaxy Gear 2, not that its overly liked.
