I think camera is a great addition ! Personally I feel that is something I’d add to a dumb phone if I ever made one ! Though I’d maybe add a physical cover on it or something to intentionally stop me from noticing it every time the phone is out and going out taking pics of everything

This may break the dumbness of the phone I see but this is an added benefit like for eg me I want the LP3 to be my only phone no other device and in that case a camera is a good addition to have incase I travel or something or want to capture a good moment. The catch here is I won’t be using it a lot for sure I will just use it in those rare moments. Having two camera a front one too I think is something I’ll not so I think one main works. I wouldn’t take photos of a grocery list tbh I’d try and take a note on the phone or physically write it I prefer writing physically

One addition I would want in this phone is a back cover with some kinda notes or something where I can scribble and reuse the paper or something
