Just wondering about this. I’m sure it’s possible. You can look at certain histories on apps and on browsers within the phone. But can you know whether or not someone entered the phone, looked at photos, contacts, etc. I’m sure it’s technologically possible to do this
In a situation like that, Screen Time (built-in feature) may give you some hints; explore it to see what sort of information is available. Based on that info, since Screen Time gives a daily/hourly breakdown of app usage, you could conjecture what apps were used for how long at which times, although all this info usually can’t be determined precisely.
Great info , thanks !
