A yellow tint appeared on the screen near to the volume and power buttons. Took phone to the service centre, they opened the phone and found some fungus inside due to some water entering. I don't know how. Since it is liquid damage it doesn't come under warranty. To change display it costs around ₹4800. I told them I will do it later, so they fixed the phone back and gave it to me. There is a small gap between the screen and the phone body now, I noticed it one hour later after I left the service centre. I took the phone next day but they are saying they will not be able to fix the issue. It will stay open unless I change the display. Now my phone is more exposed. Don't know what to do.
