hacking my smartphone for network

well, I am a beginner in hacking and I proposed as a challenge to be able to hack my phone, the criteria for the hack are the cell phone being connected to the internet and not being able to touch the cell phone, what I have been able to do so far get the ip address of the cell phone without touch it but now I don’t know where else to go, because I’ve tried using msfconsole to try to access the phone but it doesn’t have port tcp open and I’ve also thought of using an apk to access it from the inside out but this contrary to my not having to use my cell phone, how do I solve it ???
