I've got a 2017 flagship Samsung Galaxy, and it only ever received 1 update in 2018 - so it was considered defunct by Samsung before my contract even expired.

I've got a 2017 flagship Samsung Galaxy, and it only ever received 1 update in 2018 - so it was considered defunct by Samsung before my contract even expired. The earlier iPhone 7 it replaced got major version update support to 2021, and still gets minor patches, including one a couple of weeks ago. Even comparing like-for-like on flagship products, the androids perform poorly when it comes to Long Term Support.
