Google and Samsung already have an interesting relationship, but it is about to get much more awkward. Google has seemed a bit concerned for some time that Samsung has taken such a dominant role in the Android ecosystem. Now, Google will have a new reason to be concerned: beginning in March, Samsung will dominate Android and compete with it at the same time. According to a report from Japan-based magazine Mainichi, top Japanese carrier NTT DoCoMo has confirmed that Tizen smartphones will become available beginning in March. The news follows a number of delays that pushed the launch of Samsung’s first Tizen phone back from last year, but the consumer tech giant apparently has no plans to delay things any further. The first round of Samsung’s Tizen handsets are expected to debut next month during the annual Mobile World Congress trade show.
