Iphone 5s display turns light yellowish at the borders especially visible in white backgrounds
I am using iphone 5s 16gb running ios 8.4 more than 1 year. I have suddenly noticed that my phone display turns yellowish at the borders.
I have restarted/hardware reset-ted but still the yellowish color appears on the display.
Could anyone suggest me to fix this problem since my warranty too expired.
Awaiting reply from you friends
