Most of the people I know who have switched from Android to Apple did so because a premium phone they had purchased stopped receiving updates after the first year or so they were stuck with bugs for which the only fix was “buy another phone”.
Everyone has EOL dates in this game, but Google consumer device ecosystems are the worst of the bunch in this regard.
This is the main driver for me in considering a switch to Apple. I almost did the last time I needed to upgrade, but the trade-in offers were good enough that I didn't. It doesn't feel like an upgrade though, I lost the back fingerprint scanner that worked great, but at least I get the security updates for a bit longer.
While I use an iPhone and would recommend it , you could easily get a phone like the pixel , one plus , etc that support lineageos or other 3rd party roms and that will keep support years after the vendor does. I will probably go that route next time because it’s not like the phone is unusable or slow after no more updates.
I have been on pixel my last few phones (currently on 6a). While I've done 3p roms on my phones before, I'm not as interested in tinkering with them anymore.
The phone that I got before my iPhone was a razor phone 2. I was hoping it would be one of the last androidphones I'd have to buy for a while due to its beefy specs.
Unfortunately they dropped support for it within the year that I bought it and it never got the latest android. Now it's it's in my basement.
