Samsung Galaxy S5 remains the most popular Samsung handset in the US
Samsung smartphones are very popular in the US, especially its Galaxy flagships. However, the Galaxy S6 or Galaxy S7 are not as popular as their predecessor that launched back in 2014 and has about 50 percent more users than each of them, namely the Galaxy S5.
According to Kantar Worldpanel, "As of February 2017, the Galaxy S5 remained the most popular Samsung device in the US, with 15.6% of Samsung’s installed base. This was followed by the Galaxy S7 at 11.5% and the Galaxy S6 at 11.4%. The Galaxy S7 edge accounted for 5.8%." Considering the data above, we could also say that the Galaxy S7 is Samsung's most popular flagship family in the US right now.
The same source also reveals that twenty percent of Galaxy S7 owners plan to upgrade in the next year, while more than half of the Galaxy S5 owners in the US have the same plan. However, more than three-quarters of the Galaxy S5 owners think about a new Samsung handset, but only 64 percent of the Galaxy S6 owners have no thoughts to go with another brand. Kantar Worldpanel did not reveal the percentage of brand preference for the Galaxy S7 owners who are planning to upgrade already.
