If you notice on your Samsung Galaxy A5 that when you press the soft-key buttons you do not feel any vibration, then you might want to activate the haptic feedback in the settings.
However, you will need to look in the settings of the Samsung Galaxy A5 a long time for this option, because it is not available. If you also notice that the Samsung Galaxy A5 does not vibrate even for oncoming new calls, then you can change this at least in the settings.
To do this, navigate from the home screen to:
App Menu --> Settings --> Sounds & Notifications --> Vibrations
Here you can activate the option "Vibrate when ringing". Afterwards, you will also receive the vibration as a notification when a call comes in.
Even if the Samsung Galaxy A5 does not have haptic feedback, as is the case with other Samsung smartphones, so at least the vibration on calls is possible.
