Been using my Samsung A8 for 6 years now and while its still doing great (no battery issues, still decently fast) the camera quality, some fast charging issues and storage means I’m due for an upgrade.
I’m a bit out of touch with Samsung’s current offerings but ideally new phone would be one that can handle professional work like emails, editing etc (work in marketing).
If you’re going to use your phone for your job maybe look for the S series
