Screen burn in z5 premium . Started on left side, now right side taken over. After 10 months of use, screen dying. Previously I had Xpedia X1, Z ultra and now z premium. Their screen was good. But I think it's 4k, due to processor and screen it's dying. Sony is cheating with these products.
Also having this problem 😡
Phone is 7 months old
Mine too after a year... (XZ premium)
Funny thing, I searched "burn marks on phone screen" on google, then images, and the 1st picture linked me to this forum!!
I have 3 marks on the right side, same as the picture above. I hope it won't get worse...
That's usually caused by stress on that side of the screen
As for the other comment, it makes sense as you were searching for issues with this specific Xperia/Sony, and this is the Sony Xperia support forum, it adds up
Thanks for the reply 
But I just Googled image "burn marks on phone screen", nothing related to Sony or Xperia 
Anyway, it seems to be a recurring issue, no matter the brand.
I just hope my phone will last until a new Sony release (like a XZ3 premium
