Defective screen on XX?

[Dessyassassins]

Hi there,

I have been having problems with my Xperia X's (F5121 *Swedish import by Sony NZ) screen retaining images, and sometimes for extremely long periods (still visible after 30 minutes). It started happening shortly after I bought the phones and progressively worsened over the 9 months of ownership.

Here are some pics. 

Is anyone else having the same issue?

usually its a screen problem. but first have you run the screen tests?if it screen problem or not

Yep, I've tried the built in black and white test as well as RGB test from a 3rd party app.

No stuck pixels except for screen retention from the previous app.

then just go to centre and claim waranty. better that way
