Re: Google is taking the lead on revitalising the patching pipeline for the Android ecosystem
I'm not sure that Google are entirely the problem. Manufacturers and their Android skins mean that there's always going to be inertia in getting ports to earlier versions. Then there's OnePlus, Cyanogen and others who have their own versions of Android.
Finally, there's the replacement cycle. With phones on 2 year contracts there's little incentive to fix problems when manufacturers know that the phone is going to be replaced with something else relatively soon. If there's little incentive to fix a relatively new phone, there's none to fix something that's second hand.
It's a mess.
