Screen quality problem

[epcd0728]

My Z1 (C6906) screen has a problem.

As you can see in the photos below, bottom of the screen, there is a blurry thick line.

(those photos are captured from a youtube video which explain exact same problem mine has)

I didn't drop the phone and didn't do unlocking and rooting. Only thing I did was flashing s/w to update to sony stock generic version .257 from xda.

Can it covered by Sony warranty?

Yes you can,but first you can try bring it to the shop where you buy and showing them about this issue see they can replace another unit for you or not.if cannot then u just need to send to local sony service centre and let them know about your issue.
