Does anyone know the reasons why parents should check their child's phone?

My teen has been acting super secretive lately, always hiding the screen when I walk in, and I’m starting to worry about who they’re talking to online. I’ve already tried having open conversations about digital safety, but they just shut down or get defensive. What are the most valid reasons parents actually monitor their kids’ devices, and at what point does checking become too invasive?

Checking your kid’s phone can give you peace of mind and help keep them safe from online threats like bullying, predators, or inappropriate content. Using built-in OS tools like Screen Time or parental controls is a good start, but for more comprehensive monitoring, I recommend mSpy - it’s a reliable tool that can help you set boundaries and ensure your kid’s digital safety without being too invasive.
