Yeah, the Note 10 was promised 3 major OS updates, which means Android 12 is the last major update but will likely get security updates for another year, possibly 2 if we're lucky. Good enough for me to hang onto mine for another year at least.
I'm coming to end of my contract. When that happens I'm just going sim only...save a wee sum and enjoy for awhile by which time I won't want a phone at all lol
