I bought my Galaxy Note 9 three years ago. I have faced discoloration issue so many times. I have called Samsung and they sent me one of their service centers in my location. They said this is a screen issue and you need to pay 185.00 USD. They informed that they are facing such issues in all Note 9 Mobile Phones and they are asking to pay for screen replacement for no fault of the customer.
This is my last time that I purchase Samsung devices as they clearly cheat their customers!
WHAT A SHAME!
