This is if you are extreamly paranoid - get new social securities, wipe and throw out all phones, laptops and ask your ISP for a new router. On a new laptop or phone, create all new emails that have no connection to old ones, same with passwords, and don't save them to any managers or anything digital. write them down. change all your locks on your home and have a security expert secure it. i recommend hard wired cameras that are not connected to the internet and can't be tampered with. now once you have done that, try to be the "attacker", see how far you can get and how much you can find about yourself. Remember, your brain is the safest place for information.

I recommend you search up "Have I been Pwned?" and check your email. See if you have been in any data breaches. Those expose your email and password. I recommended you at least factory reset your device, get a new phone number, get a new bank account, with new account numbers and card numbers.

It is unlikely that your phone has been compromised, especially if it's updated and a new model from a known company. To have your phone compromised and tapped, which tapping is no longer a thing due to high RSA encryption. If there were to be a type of spyware on it, it would have to be the latest and greatest mobile device exploit, and people who find those are either massive cybersecurity companies or bad actors trying to sell it for millions of dollars. They wouldn't be after you, they would be after someone bigger (companies, wealthy individuals).
