Samsung’s flagship Galaxy smartphone sales cycle restarted yesterday with the announcement of the Galaxy S7 at the Mobile World Congress in Barcelona. Last year’s Galaxy S6 becomes Samsung’s mid-priced phone and the one from two years ago becomes an entry-level phone sold in developing markets and with a prepaid plan. Big premium sales revenue must be kick started with this announcement to carry Samsung through Apple’s iPhone 7 announcement in September until it returns to Barcelona to announce the Galaxy S8 at Mobile World Congress 2017, starting the cycle all over again.
