My apps don't stay locked! Even unistall prevention doesn't work. Everytime people get on my phone they keep unstalling my apps. I wouldn't recommend this app.I had download them again. I don't use this app anymore. It doesn't protect my apps all of the time.

This the only one able to lock Recent apps, even in newer Android versions. Fast & Lite. PLEASE JUST ADD A FAKE ERROR MESSAGE/COVER feature.
