Developed by XDA Member MasterYus, VibeOnKey lets you add and manage additional feedback to your hardware key interactions.
The app relies on the Accessibility service to catch key input events. With this app, you can add and manage vibrations on the hardware buttons of your device, control the vibration intensity and even add sound feedback! The app works on devices with Android version 5.0 and above, and does not need root access for its functionality. The developer also promises the app to be simple to use, battery efficient, and lightweight.
