We have a 2 year old and we don't use our phones or devices when she's around unless it's a video call from family or an important phone call.
We're happy with the results so far since she's turned out to be a very patient, intelligent, and attentive child. She finds enjoyment in books, puzzles, drawing, cooking, gardening, cleaning, unloading/loading the dishwasher, laundry, and all sorts of activities her overstimulated peers would find boring nowadays.
