mobile

I have just received my S6 edge. No scratches. Everything running uber smooth.
I launched the phone, linked it to my main google account. All apps and data synced.

But now, I am not able to add another google, nor email account.
When I try this and fill in my credentials of the to be added account, the phone mentions that 'email has stopped working' or 'google services have stopped working'.

I have installed the latest updates;
Rebooted the phone;
Tried via the email app as well to add accounts.

Any suggestions what might solve this?
