ScreenLock is a tweak launched last night in Cydia for iPhone, iPad or iPod Touches, giving us the possibility to additionally secure iOS 9 installed in our devices.
More specifically, ScreenLock blocks the possibility of using the Home button or accessing the Control/Notifications Center when the terminal screen is locked, so no one will be able to unlock our devices without a security code or read notifications.
Compatible with iOS 9. While ScreenLock is active, the screen, home button and Notification/Control Center are disabled. Configure Activator from Settings.
ScreenLock is available for download from Cydia's BigBoss repo.
