Closest I've seen is Sony.
The problem is reliance on Qualcomm, who have always hated GPL software, and their driver support shows it.

Even though I dislike Sony recently, they were awesome -- up to their Z3 phones and Z4 tablet releases. And they don't abandon their devices as quickly as everybody else.
Marshmallow was released in late October 2015 [1]. Meanwhile, the Z3 only just started rolling in early April 2016 [2]. That's pretty mediocre if you ask me.

Eh, anyway. Peculiarities with the release schedules are sadly the norm.
