Screen "BURN" like issue

[DavidCollins]

Literally.. My screen is burning up

 My XPERIA X which is slightly more than a month old is losing its screen. That burn on the image shared stared lightly and it's growing. Started with top left of the screen now coming down and also top right is beginning. And not just mine, my sister who has a similar device, is experiencing the same problem. I was loving this device but with this? It's a major blow to me. Also, my camera overheats even on safe mode. Can't take a video for more than two minutes. Device is an Xperia X (F5122).. I have No protective cover and no secondary screen protection. Any solution on how to stop my screen from burning out?

I really don't understand why Sony isn't fixing this problem. It can happen with every Xperia device. Besides some small problems that every phone has, this issue is driving me crazy. Does anyone know what is causing it?

I've never had this, and if I did, my IMMEDIATE first step would be contacting Local support for a repair.

It should be your next step too.

I actually have. The  response was that I had to change the screen. Though they have no idea on the cause, so even if I change the screen, It may still suffer the same problem. I can't be in a loop of changing the phone screen every two months.

Yes that's it. Every 2 months. I don't have it with every Xperia, but if it occurs it always returns...
