In iOS 10 the Apple company has implemented a vibration that is run when we lock our iDevices, the motivation for this change not being disclosed by those in Cupertino, but if you hold the terminal in your hand without paying attention, then this vibration will indicate the moment in which is he blocked.
If you wanted to implement this change including in iOS 9, well, a new one tweak named HapticLock offers us the possibility to do this extremely simply, its installation activating a vibration that is run when we press the Lock button of the iDevices, so you will have in iOS 9 a function offered only in iOS 10.
Compatible with iPhone on iOS 8-9. On iOS 10, when you lock your device, you get a little vibration called an Haptic Feedback. HapticLock port this feature to iOS 9 and below. You will have a Haptic Feedback when you lock your device. No options to configure.
HapticLock can be downloaded from Cydia's BigBoss repo following this link.
