The good news at least, is that the Nexus 6 seems unaffected by whatever this is (and may in fact be at the core of this). Nexus 6 shipped with 5.0.1 and I'm not aware of any Nexus 6 owners seeing this problem (when running stock 5.0.1). It's mostly the pre-5.0 android phones that are having this problem when upgraded to 5.0.1, so my guess would be that it either doesn't happen with a stock (from scratch, not upgrade) install of 5.0.1, or else it's some difference between the hardware/firmware in Nexus 6, and every other Android phone.

There are around 7 replies in that thread specifying they have a Nexus 6 and see the issue.

I have one, but have not noticed it. Though I always use it with a BT earpiece, so that might account for the difference?
