I don't know what options are available to you where you live, but in the US there are local credit unions which have banking available via browser portals.

I use a Light Phone II which has a black-and-white e-ink display and no ability to display images or install applications beyond tools that they develop in-house. It's been great.

I, too, have problems with infinite scroll apps. It's been really beneficial to my mental health to ditch the smartphone and delete my twitter/instagram/facebook accounts.
