I believe that children between the ages of 7-10 should be given access to a smartphone. I feel this way because around those ages children are developing into responsible young children and they need something to show that they are responsible. They also need something to entertain themselves.
Little kids should not be give any Social media or any access to a phone. Kids shouldn't have any access to a phone or social media until their age 12-13 because I think that it's right for kids to be given social media when they are mature enough to and they are smart enough to not make bad decisions.
Explanation:
It is known that kids do not become mature until ages 18-25
