I am experiencing the same issue with my sony xa ultra. What could have caused this problem and how to fix this.

I also have this problem with my phone it started last night after I went out for a run. The lines come and go, is there some fault with the graphics on these phones?

I have the same problem.

Taking a screenshot is not possible. When you scroll, the lines stay where they are.

I turn my phone on and off numerous times, and then it seems gone.

Very visible on very light and very dark background.

This was too expensive to be failing after 6 months of purchase! Hasn't happened in a while, and now twice today.

I have the xperia x compact.
