Re: Two years?
Over a five year timescale, brands can rise and fall so no Android vendor can rely on your repeat custom then - they might not be around (or competitive enough) to take advantage of the good will they can foster in you by updating your £350 phone for that length of time. Nor does it help that in two years time an equivalently specified handset might only be half the price, so most buyers will likely buy a new handset after a few years for reasons beyond discontinued software updates, such as a failing battery or cracked screen.
If you want a three year software update cycle, you can either buy a handset that looks likely to be well supported by the ROM crowd, put your faith in Google's Project Treble, or buy whatever the successor to the iPhone SE will be.
