As the title says. I can get physical access to my Wife's phone, typically when she falls to sleep.

Now I'd much rather go through her phone after she goes to bed than go through the hassle of rooting her phone and installing spyware on it. But there's always that risk that she could wake up and catch me. Which usually forces me to go through it very quickly and missing a lot of info as I'm basically skimming through most of it.

Does anybody here have any suggestions or tips on what I could do to minimize the risk of getting caught while going through her phone?
