I am generally happy with my new pixel 2 XL. However after only a day of use, the display started to have severe colour distortion. Everything become greenish. Originally I thought it was the screen protector,but when I take the protector off, still the same. My emojis all looks disgustingly yellow-green. How should I deal with it. Shall I contact the seller for an exchange or Google for repair? What could be possibly wrong?
