i use an S10 currently which is already old, iirc it still prompts me for updates. In any case realistically i ll buy another phone in a 1-2 years. The interesting thing is that these iPhone buyers do the same, they keep buying the new models instead of keeping their old or buying used ones, so it can't be the superior updates support.

Frankly i think the biggest driver for iphone replacement is screens breaking. It's very costly to replace that on an iphone
