My friend suspects that someone is using her phone. She changed her security code, but she is still afraid that it might be stolen again.
I was wondering if there's any built-in logging history or any 3rd party app which allows to see history of phone usage (what time someone unlocked lock screen etc.)?
In addition, is there way to set up two-step authentication for phone unlock? For example, after typing your security code, you have to type some another password, do face unlock, or whatever makes it harder to log in.
