Samsung India — Galaxy note 5 purple screen need to be replaced

Address:

Bangalore, Karnataka, 560037

Hello Sir,
Recently all of a sudden my galaxy note5 has been showing purple screen on top and it's day by day increasing and getting darker.
I have been a loyal customer of note series beginning from note2 itself.
I am sure I haven't wet or dropped it and there isn't any single scratch on the phone. I buyed on nov2015 and it's still in warrenty, So i am need replacement of screen .
