Mihai is a blogger and column writer at SamMobile. His first Samsung phone was an A800 which took a lot of beating, and a part of him still misses the novelty of the clamshell design. In his free time, he enjoys watching shows, documentaries, and stand-up comedy; listening to music, taking walks, and occasionally playing old(er) video games.
