OnePlus One owners, Lollipop 5.1.1 is finally rolling out. The Cyanogen 12.1 update, which is based on Lollipop 5.1.1 is starting to roll out via an over-the-air update. The update is a rolling update so it may not be there for your phone just yet (I know my OnePlus One hasn’t seen it yet) so be patient. It will be coming to you over the course of the next few days.
There are a lot of improvements, fixes and changes in Lollipop 5.1.1 that OnePlus One owners will benefit from and of course this will put you on the latest update of Lollipop which isn’t such a bad thing.
