Samsung galaxy s7 edge touch suddenly unresponsive

[Cyclor]

Hi,
I bought a brand new samsung galaxy s7 edge 2 months ago. A couple days ago I charged the phone overnight and when i woke up in the morning the touch screen was unresponsive (the screen is still on and i get notifications but the touch just doesn't work). Iv'e tried to factory reset the phone but it didn't seem to solve the problem. Is there any other solution still available except for replacing the screen? And if a screen replacement is required which part of the screen do i need to replace?

If it's brand new, it should still be under warranty

The problem is that the warranty isn't valid in my country because I bought it abroad

That is very strange. Do you have a case on it?
