LEO Privacy is very useful , I have friends who I let borrow my phone and they like just going through shit without asking ...I don't mind it since it's been only a month since I've bought this phone, but now that I've had it longer I have more private info stored and well, LEO Privacy really does the work on keeping my friends out , and its also awesome for the simple fact, if someone tries to intrude your phone it snaps a picture of them if they get your password wrong ,very secure.Leo privacy is small in mobile phone,locks apps boosts the phone and many,the best application I ever downloaded and also good for low ramed phones.Very efficient, really keeps snoopers out…I suggest all my friends to use this. I am very Happy and satisfied. You can lock any apps, memory card, and gallery. Fantastic.....
