In this video, Andrew Tonner examines the profit potential for the new Samsung S4 smartphone. Using data from IHS, the S4 costs more to build than the Galaxy S3, courtesy of a larger, higher-resolution screen. But even so, 60% of the S4's components are made by Samsung, thus limiting the actual cost to the company. Right now, the big unknown is what Samsung will charge consumers for an S4 -- and that doesn't include the contract. Nothing is terribly clear at the moment, and Andrew encourages keeping a close watch.
