Dumbphone for a senior?

Hi! I need to buy a phone for my grandma and because she is not really technologically literate and her current smartphone seems overwhelming for her I consider buying her a dumbphone. I had this idea that it's just gonna be like a simpler smartphone. However, as I researched the topic, I got a bit disillusioned. Phone from which you can only call and send sms is only viable for somebody who also has a computer, and just wants to reduce their screen time. She would also need to use her banking app, plus some other apps like spotify. Is there something like what I am looking for? A simpler phone, but still with android so you can install some basic apps? Or should I ditch that idea and just buy her a smartphone if thats the case
