Android has a lot more problems than you think and Google does nothing to solve it.
We need a standard ARM platform, just like we've had the x86 platform since roughly 1981. And Google has all the resources to create and enforce it. And since they don't I wonder if they are malicious or negligent or it's just part of their business plan which is called "planned obsolesce". Too bad, in Google's case this obsolesce involves even original Google devices like Nexus 5 (stopped receiving any updates since October 2016) and it will soon be joined by Nexus 6.
That's just horrible.
