Hi, and welcome to the UK community

There's a diagnostic available via your Samsung members app. Just head to the Support section and tap on Diagnostics

You could also try a hard reset

With the device powered up, Hold the Volume down button and Power button simultaneously for 10 seconds. The screen will go off. Continue to hold buttons until the device vibrates and the Samsung logo appears. Release buttons. Device will reboot. Once done, please check if the issue is resolved.

I've tried to use the diagnose option and it doesn't vibrate

If that's the case, then it really needs hands-on by an authorised Samsung repair centre.
