I didn't say anything about corporal punishment. I believe it works, but everyone should use discipline specific to the child, IMO.

Kid isn't supposed to make a hotspot but does anyway? Lost that phone. Kid is playing games on the PC? Remove the games. Etc.

If the children aren't listening to their father, the problem isn't android parental controls.

The buzzword you’re looking for is authoritative parenting. It’s about setting boundaries from love instead of fear and demonstrating mutual respect. It’s a lot easier to get a kid to listen to screen limits when they see you as a loving and responsible person, and especially when you have fun things to do with them off of a screen, and a real relationship with them.
