Next Year All the Samsung phone going to make with aluminum, So Samsung Galaxy S5 can be the first aluminum phone from Samsung. When it’s coming with Aluminum body cover Samsung should consider about the phone’s weight and heat system. Earlier Days Nokia also made some aluminum metal phones but while we are talking on the phone the heat goes high. HTC One series cant see any complaints about the heat. If Samsung consider about the heat and weight they can reach the more Smartphones market.
