Smart phones and children have a tricky relationship. Phones can be most entertaining thing for kids. Nowadays every kid wants their own smart phone. But as a parent when you hand off your phone to your child, you should know how to set up parental controls for an Android device:
Play Store Parental Controls-
If your children are 13 or above then you need to use the built-in parental controls in the Play Store. This lets you limit games, movies, TV shows your child can download, based on an age rating. To set up parental controls, open the Play Store app then go to settings> parental Controls, then toggle the switch On. Next, click through each type of content and set an age limit, or activate the explicit filter, and hit Save when you�re done. Your child won�t be able to buy or play anything that falls outside these settings.
