Has anyone figured out how to access another mobile through wifi

I’m curious whether a phone connected to the same home Wi-Fi can be accessed from another device without touching it. I tried searching around but found conflicting information-does this actually work?

I’ve seen this question before, and the answer is no, you can’t directly access another mobile device just because it’s on the same WiFi network. For parental control and monitoring, I recommend using built-in OS features or a reliable tool like mSpy to keep an eye on your kids’ devices.
