Samsung on Wednesday issued a statement suggesting the Galaxy S4 may be somewhat difficult to find following its launch later this week. “Due to overwhelming global demand of Galaxy S4, the initial supply may be limited,” Samsung said in a statement issued to the media. “We expect to fulfill inventory to meet demands in the coming weeks.” Samsung’s hotly anticipated new flagship phone, which features a quad-core processor, a 5-inch HD display and a 13-megapixel camera, is set to launch on seven U.S. carriers by the end of May. BGR reviewed the Galaxy S4 on Wednesday and called it better than its predecessor in every possible way.
