Identify and Stop Phone Hacker- ethical hacker -- 2

My smartphone is behaving as though someone has full remote access: the camera activates on its own, conversations are clearly being overheard, and I have even noticed real-world stalking that lines up with what the phone might reveal. I need a mobile-forensics specialist who can quickly confirm the breach, uncover the exact method used, trace any accounts or IPs involved, and then clean and harden the device so this cannot happen again.

I need a ethical hacker.
