The OnePlus One has been a remarkable smartphone, availability and issues in India notwithstanding. It has stayed true to its name of a being a flagship killer, at least for 2014's batch. But with 2015's roster already on their way, the smartphone might be showing its age. It doesn't mean, however, that it will no longer be useful. Somewhat like a Nexus, the OnePlus One could be taken to new and quite different heights, as this recent hack proves, showing the smartphone running Sailfish OS instead.
