Yeah these are Pixel phones I believe which is good. I think they are brand new, which can be a pain because it does profit g*^gle but I tend to keep a phone for a really long time. I don't want to say what version I've got now LOL
Yes indeed it is very frustrating and unfortunate people get so beat down they offer virtually no resistance to the insidious crap!
Devices are supported for 5 - 7 years. That is enough for most use cases. I normally switch the phone once the battery stops holding the charge.
