Samsung is ditching plastic in favor of metal on its new smartphone, abandoning what some critics have called a cheap aesthetic. The tech company’s new high-end smartphone, the Galaxy Alpha, will go on sale in September. It has a metal frame on the four edges of the phone, Samsung said Wednesday, and will launch in five colors including black, white, gold, silver and blue. Samsung said in a statement it was taking “a fresh approach” to its hardware design, “based on the specific desires of consumer markets.”
