On the S7 I got security updates up until September 2020 IIRC. I anticipate the S10E will continue to receive security updates for just a little while longer and it's currently on Android 12.

My point was that old Android phones "not working" after a few years is complete bs. The S10E was launched in March 2019 and still going strong.

EDIT: Looks like the S10E is still getting monthly security updates too: https://doc.samsungmobile.com/sm-g970f/xeo/doc.html
