lol, no? The most I got from Sony and Samsung in 2012 and 2015 was 1-2 years. Which is when I generally stopped using Android. It was frustraing enough to read all the news about "Google releases new Andoid with (list of features)" then asking when is my Sony/Samsung is getting that? to hear "oh maybe in 4 or 6 months if you're lucky. Or download this random ROM from `appzworrier` on xdaforum. Surely they haven't put any malware in the ROM or you'll hear about it here". I did give it another shot in 2019 with a Pixel 4 phone then after 2 RMAs with battery issues (4-5 hours of battery) I went back to iPhone. Funny thing is in 2013 and 2016 I switched back to the old iPhone I had before the upgrad, I just updated them to the latest iOS version there was at the time. After the shitshow I had with google support in 2019 I just gave up.
GKI didn't exist in 2012/2015, so it was very difficult and expensive for OEMs to support Android for longer. Apple could do so more easily because they control both hardware and software. Google introduced GKI and other related efforts/architectures to address this very problem, which is unique to Arm, Linux and the ecosystem around it.
It's really silicon manufacturer's fault for not wanting to mainline and long-term support their BSP, not Google's.
If a device cant get play certified it cant realistically be sold anywhere in the world except china, so no phone manufacturer would choose a SoC for their phone that was not supported.
