I have the same phone but to be fair some websites stopped working (GitHub is among them) and some of my banking apps stopped getting updates as well.

No huge deal breakers _personally_ as I don’t need banking on my phone anyway (I have an iPad at home, and also checked that the banks offer authentication devices like TAN generators if I really need to get out of the iOS/Android ecosystem).

Apple Pay still works fine.

I hope that small phone has a long life ahead of it still :)
