How can I effectively monitor my child's activity on his smartphone, especially when he started showing strange behavioral signs after spending a lot of time online? Maybe someone has experienced a similar situation and can share some advice.

If your child is showing strange signs after many hours online, monitoring her activity on your smartphone can be helpful. I recommend an app I've used myself, which is mSpy. It allows you to track text messages, calls, social media, and even your child's location. This will help you better understand his online behavior and respond to any strange situations in a timely manner. Check out the review at https://theteensafe.com/mspy-review/ to learn more about its features.

Use parental controls, activity tracking apps and trusted communication to monitor your child's smartphone activity and identify strange behavioral signs. Talk to your child about their online experience and help them develop healthy internet habits.
