Question about OnePlus Nord 2 (12GB)

Attention for those who get it from Italian Switzerland like me. Setting the language to Swiss Italian the display starts blinking and I can't configure it, it stops only if I put it on charge but once I remove the charger plug the screen turns black and only by reinserting the plug it magically returns to work. I've reset it a couple of times but unfortunately the problem is still there. I was about to call the service department to return it, but I thought to myself: what if instead of setting the language to Swiss-Italian I try setting it to Italian? Well yes it worked perfectly and so 99% it's a software bug and I didn't make the return because it works great and it's a great phone. Hopefully the bug will be fixed with a future update even if it's not that serious knowing how to work around it.
