I think Once you’ve lost your privacy, you realize you’ve lost an extremely valuable thing. Please say your ideas.
I've always had a very simple policy when it comes to people (mainly my parents, boyfriend, litter brother) looking through my phone or computer:
You can if you want, but when you find stuff you didn't want to find that's on you, I ain't losing sleep but you probably will.
I keep plenty of shocking things on my devices, some of it for no reason, some of it for very particular reasons. If someone went through my phone they would cause themselves more problems than they caused me. So far no one has tried it.
So I used Applock DoMobile. I am using it from couple of month on my Xperia Z phone.. And if I want to know who tries and fails to get into your apps, It has just introduced the Intruder Selfie. Other features are good like locking files, videos, photos, or harassment intercept etc. No one can view my secrets. Smart.
