Can you clarify @Members_4rlhED7 

Did you send the phone to a Repair Centre to be fixed that's not an authorised Samsung Service Centre ?

Or did you send the phone to Samsung and they sent the phone to this repair centre ?

When phone has been owned for a certain amount of days Samsung can only offer a Repair and not a replacement.

This cooling off period maybe different in other regions.

You say as far as your aware it hasn't been dropped. Is there a chance it has had an accidental bump  🤔 

I wish you all the best with this.
