Thanks Nik, very helpful. Looks like I may just have to live with some shortfalls on this handset - also since found out there's no Always On Display either, which is more of a pain as it was handy seeing all the notifications on that particular screen.
My old one was a Samsung Galaxy A3 2017 edition, last running Android 8, but I guess features like the Always On Screen might be more handset dependent than on something else?
