Blue patches or cloudy textures on the display
Today morning I have noticed that there is a blue cloudy effect/patch on the lower right corner of the display. After 5 hours, this had spread to the complete right side of the screen on the edges. For example, this is like a magnetic problem happens on the old CRT Television screens. The screen is having a blue tint and it is horrible to use it. My phone is just 6 months old and no change or difference in the way I use it.
It is not there on the screenshot I take by using the Power + Home button.
Change: I have upgraded my iOS to 8 2 days back. Need help ASAP.
Things tried: Restarted the phone, Resetted the phone, Restored the phone as instructed by the Apple technician and a senior advisor. Spent 3 hours on the chat. Still no luck.
