Weird Problem on New Z1

[Wildwolfie]

Hi guy,
I bought a brand new Z1 a month ago and yestersay it started acting up. I updated to 4.4.4 from 4.4.2 about a week ago (just so you know) it didn't have a single problem then. But now it heats up rather unusally more than it used to when it was doing the same things before yesterday and when I charge my battery it heats up like **bleep**. But the main problem is when I lock my device the display doesn't fully turn off it goes black up there is a light or backlight some gloomy light on the display and it's creeping me out I haven't done anything for this to act in such a way no root bootloader locked I dormitory even try to do any of those things three screen is partially on and @night in the dark you can seen it's on and bright compared to total darkness like when I turn my device fully off and there is also some minor lag and crashes like shazam and messenging Apps also a really weird case is that when I turn the device off and on again the battery has depleted by 9-10% so any answers are welcome and please keep in mind that warrenty is my very last option because there isn't a Sony service station in the whole country where I live (Sri Lanka) so I Have to Ship the phone to get my warrenty.
Thanx in advance

Hi, 

I have the same problem regarding backlight in my Xperia Z1. I run "SOFTWARE FIX" via PC Companion, but it did not solve the problem.

Do what should I do in this case? This problem is affecting battery lifetime I think, can I expect SONY to replace my phone to new, properly working one in terms of warranty?

Thanks for answering,

Regards.
