New s5, screen gone greenish

[AC Question]

Bought a new s5 the other day and 2 days later the screen (i think its the back light) started going greenish in colour. it will revert back to normal after a while and the phone is working perfectly, any body know why this would be happening and how i can fix it if at all as its very annoying to look at!!

If it comes again, I advise you to give it back to a new one
If it's hardware, this could happen again :s

I don't think I'd even wait for it to come back, since it's brand new. Bring it back now and ask for a replacement while you can.
