So, you can see it on the photo - a circle with a pale dot in the center. I wouldn't say it bothers me a lot, but that's really strange - I only have the phone for 2 weeks, never dropped or stored with anything in a pocket, and it doesn't look like a scratch. It also becomes less visible if I clean it with a microfiber cloth, but comes back as soon as you slide a finger across it. Any ideas?
the discoloration is probably because there is oil from your fingers on the area or it came into contact with water.
try to clean it with a damp microfibres cloth, if that doesn’t work try 70% isopropyl alcohol
