There are certain things which when given more than required creates addiction, body harm, dopamine rush, etc.

Same way, we see that phones are given to kids just to keep them distracted while their parents are busy or working.  This is good when screen time is limited. When the screen time is increased or phones are given more frequently to kids, we can notice that kids tend to throw more tantrums, get bored easily with everything, get addicted to the screen. It increases the dopamine production which leads to addiction.

Giving phones during emergency or after a certain age has a different effect on children. They get matured and know what they are doing. During the mature period of their lives, they can utilize the phone as a resource and make something good out of it, but on the other hand if we keep giving small kids phones regularly it could also destroy their mental peace. There are many hospital cases where parents have given more screen time than required, which ultimately lead to mental illness of the child. The symptoms like throwing tantrums, crying and shouting continuously for smartphone, blindly doing whatever smartphone says, watching youtube or any other apps for hours, not listening to parents, disrespecting elders when they not give the child what it wants.

So, parents should know the limit of screen time and the right time to introduce their child to smartphones. It will keep the children from damaging eyesight and protect mental peace.

Hence, it is said that the forbidden fruit that is smartphones are sweeter which means it can be utilized in a good way after a certain age.
