Last week Samsung updated its flagship Galaxy S smartphone with a solid incremental upgrade that will cement its dominance of the high-end of Android, helped by a $14.7bn marketing budget and wide distribution

Impact will be strongest on other Android OEMs: the preceding S3 was heavily outsold by the iPhone and the new model is unlikely to change this, with similar design and positioning

Samsung’s launch event found room for a tap-dancing child and a live orchestra, but Google and Android were invisible. Samsung is clearly trying to relegate Android to a commodity and make its own brand dominant

Major European mobile operators were downbeat, with mobile revenue growth in Europe still massively underperforming the US, and their (misplaced in our view) anger at the OTT players being channelled into promoting new mobile OSs to compete with both Apple and Android

Samsung is cementing its dominance, while the other branded players focus on flagship models to try to cut through the noise. Meanwhile the flood of Android from Chinese OEM/ODMs is growing, at increasingly good quality. All other mobile platforms appear increasingly marginal

Superficially the handset industry appears to be stabilising around Apple, Android, and Samsung, plus the Chinese long tail. However, Apple, Google/Moto and perhaps Amazon may well all have disruptive moves planned for this year

Facebook’s announcement of Graph Search, the company’s first move into socially-powered search which now in beta trial in the US, leaves many details unanswered including full launch and monetisation plans. Reliance on user-generated content from Facebook friends limits the usefulness of Graph Search as a conventional search engine and hence its impact on Google and other web search businesses in the near term. In the longer term, Graph Search could become a powerful recommendation engine for certain categories like travel, but its dependence on user data and privacy restrictions are likely to limit its wider utility and revenue potential.
