Phones haven't updated since I've upgraded
I upgraded 2 of my phones almost 2 years ago. Since then none of my phones have updated. I currently have a samsung s8+, note 8, and note 5. I have tried all recommendations that have been offered... clear cache, factory reset. I have spoke with both AT&T and samsung and I even called and had my s8+ and note 8 replaced while they were still under warranty (about 1 year ago). Even after all of that not once have any of them updated. I almost have all my phones payed off now and am debating if it is worth staying with AT&T if I keep having this problem.
