UI FeedBack

Vibration
Vibration enables haptics enhance interactions and convey useful information to users through the sense of touch. Haptic effect simulates physical vibrates when an action triggered. On iOS vibrate which has three level as high, medium and low works on only on iPhone7 and above. Android Vibration Effect's time can be managed depending given value.

Using Vibrate Effect With Notifications
When a notification is received vibrate effect can be used all the way.
