I have a Nexus 6P Android phone. Its security support ends in about half a year. It's in perfectly good shape, and I have no performance or other problems. I am happy with the phone. I would prefer to not have to change the hardware, but I don't want to be without security support, either. This is a dilemma Google has created for me.
I could put a third party variant of Android on the phone, but that seems like becoming a sysadmin on yet another computer.
Whinge whinge. Rant rant.
@alienghic @liw I made a clean slate when moving from Cyanogen to LineageOS, also installing TWRP. With TWRP, updating works like a charm.
