I like my smartphone and just use it consciously. How about less black/white? I don't want to quit it. And I don't think most people don't want to either, they probably just want to quit behaviour/apps and not the whole thing. It connects me to my family and friends very well. Pictures, voice messages etc. I can dump my thoughts into a notes app to be transferred into my journal later on. I can check insta for a bit of motivation (using it mindfully!). I only have hiking, offroading and trailrunning content and I'm happy with that. Checking some nature motivates me. And if the algorithm tries to fuck me over (which happens very fast), I let it be. Works for me.
