To be fair Murtazin did not really get an exclusive look at the phone as it seems that Samsung’s partners and carriers have already seen the phone as well. He reports that the Galaxy S4 was shown behind closed doors during MWC 2013.
This seems to be in line with earlier rumors that suggested that even though the phone will not be announced, it will still make an appearance albeit shrouded in secrecy. To be honest the idea of the Galaxy S4 being built from plastic is a bit of a downer. Considering that Samsung’s competitors such as Sony and HTC have utilized more premium material like aluminum and glass, we half expected Samsung to step it up as well. Either way we guess we will have to wait until the 14th of March to find out more, so stay tuned!
