How do I know if my iPhone is being monitored?

Most iphone spy works in stealth mode so it is not easy to know,
but you can factory reset the phone to get rid of any cell spy apps.

  • Is there anyone whose iphone is not ringing to let you know your being called? Please do not say anything rude or stupid I was going through a problem with my iphone but found the solution somehow wasn't on the Internet If you can get the call sometimes. Please do not make any stupid comments like everyone knows that becuz I did not know. If you have the do not disturb on then that would be the reason, turn it off. I did not know this and even the apple store did not tell me this, or online.
  • IPhone 6s plus or 7 plus. I know the prices and what they do. But what I wanted to know is Did the 7 fix the home button problem? That s my main worry. I use my phone to text, check facebook, candy crush, look up info, and take the odd picture… Will I notice the difference between the two phones to be willing to pay more for the 7? Hoping for opinions for 6s plus and 7 plus from past of present owners.
  • If my iPhone were to be monitored, what would be monitored exactly? Can my activity be monitored? Say, I'd be using an application, whatever it may be. Could someone monitor my activities on a certain application? How does it work exactly? Can they monitor my screen? I don't know if whatever I'm saying is making sense, lmao. If it's not obvious, I'm not very techs-savvy.
