Hold off on giving your child a phone as long as possible. Once your kids are old enough (your choice...but it's before they are teens), send them outside, shut the door, and go about your business.
Tell them to come back for lunch. Then send them outside again and tell them to come back for dinner.
I mean this in all sincerity. Don't plan their day for them. Make them go out and plan their day on the fly. Friend's house a mile away? Walk over and see if they can come out and play. Not home? Oh well, walk back or head to a different friend's house. There is value in this friction.
Don't be the person who gives your child a frictionless youth. The hard way is the best way.
Let your kids go out and ride bikes and you may end up with one getting hit by a car. Those are the risks every parent has to manage.
But if we let the edge cases dictate how we raise our kids, we end up with what we don't want - overly managed bubble-youth kids who can't think for themselves.
Is that a risk or a near certainty?
It's not like they'd have a chance to get creatively bored without the (physical) activities. Instead, if they're like most teens, they'd dopamine-junkie rot with their smartphone or game console.

The problem is kids being bored can be a good thing but they are never allowed to be. When I was a kid the internet didn’t even exist let alone cell phones and the only rule was “be home before sundown”. Kids now have way too many distractions and structure and are never given the ability to explore their own world on their own. It’s been manufactured for them.
