    Samsung S4 mini.
    I have one specific contact that I can not call, a business partner of mine. Lets call him R.
    I can text or whatsapp R and can receive replies.
    R is also able to call me. I just can't place a call to him. It just doesn't ring through.
    I have checked if there are any blocks on hes number but have found nothing.
    Help please. Its beyond frustrating.

    Welcome to Android Central! Is the phone number saved to his contact correct? If you dial that number manually, does it still not go through?

    I had the same issue with my Samsung S8. I did everything - called my carrier, called Samsung, tried safe mode etc. I found a solution for my phone. In "settings" I went to "connections" and went to "mobile networks." In mobile networks I found "VoLTE calls" and it was enabled. I disabled it and found I could make the call to the other number. I then enabled it and could still make the call so perhaps there was some glitch related to the VoLTE calls and toggling it on and off worked to fix it.

    If you have the same set up, try it and see if that might be the issue for you too.

    I had to hold down on the whatsapp icon.
    Click App Info
    Scroll down and tap permissions
    Then enabled toggle for 'Telephone'
    This seemed to fix it
