Found this is my Google news feed today:
tl;dr - The Chinese will cause a tilt and shift in the smartphone market.
Will Apple, Google and Samsung lose the smartphone market?
You don't have to convice us!!HP's WebOS, acquired from Palm, is still a potential factor, especially since HP plans to release an open-source version called Open WebOS.
Note that all of these platforms -- Tizen, Firefox OS, Ubuntu Linux and Open WebOS -- are Linux-based and all or most will be relatively open compared with Android.
