Can the NSA install virus/malware into iPhone 7s?

How do they do it? How do you know if your phone is affected? Will resetting phone remove malware?

No, they don't have to, They have a backdoor into all but Apple phones. They have the ability to track you in real time with the GPS chip that you can't disable, They can turn on your phone speaker and camera to hear what you are saying or to spy on the people at the table next to you, or o spy on you from some one else's mobile. Why would they install any malware?

Yes. Secret. You don't. Yes.

No, they are not trying to install the malware but they may hacked your device and they check your phone calls and the pictures. They are not doing anything I think so. I don't know about the cases of iPhone 7. Their major aim to collect the information. They do anything when they suspected you.

Hi No that is the advantage of apple it works on two layers as Apple own the Root level no one can infect it.
