Some Sony Xperia Z Ultra users are having a problem getting the phone to wake up

Some Sony Xperia Z Ultra users are having a problem getting the phone to wake up
The Sony Xperia Z Ultra right now offers the largest screen on a smartphone at 6.4 inches. But the size of the glass doesn't seem to matter for a number of owners of the device whose unit is suffering some problems with the display. The most talked about problem deals with the Xperia Z Ultra's inability to awaken by pressing the power button. The backlight turns on, but the huge screen remains blank or shows some green lines. The OS is running while this is happening, and a few repeat presses of the power button finally brings the screen to life. After a few times of going through this cycle, owners of the device have apparently had enough.

One owner of the Sony Xperia Z Ultra says that he has to press his power button anywhere from 5 to 150 times before the screen comes back on. He also says that his display has a yellowish tinge to it. A number of YouTube videos have popped up showing the problem. So far, no word from Sony although some say that the firmware update to build version 14.1.B.0.475 solves the problem. Others say that the update doesn't help. Hopefully, we will soon see Sony spring to life with an effective update that will work for everyone.

In the meantime, you can check out some of the YouTube videos that have been posted by disappointed Sony Xperia Z Ultra owners. And if you happen to own the device and are experiencing a problem, drop us a comment in the box below.

every phone and tablet runs into issue like this but soon company sends out update and fixes it. i hope the issue is only of software and sony is able to fix this ASAP. btw the worst was galaxy s3 and note 2 with their side black clipping issue, company refused to so many customers when it was their fault.

Atleast this issue happend pretty early from the release. Sony should be able to fix it quickly. I am still getting one. :)

Now why would it be a good thing if it happened early? People are gonna be turned off from buying it, and people who owns it won't recommend it to friends.

I posted before...every single SONY device is actually a prototype for whole production time...till the end of production. And will remain as a prototype in users eyes. I thought that Trliluminos means something else then "three lines" on screen at wake up...

Cause North American carriers blow. I already imported mine so it's going on AT&T for five months and then over to T-Mobile.

no xperia defenders here.... how strange i thought they would be shout about how bias PA is and and anti sony they are this is an unfortunate defect and the last thing anybody wants to happen on such an expensive device i hope this issue is fixed for all future devices

SONY fans aren't stupid. They will say PA biased when PA is being biased not this kind of issue.

I do not consider myself blinded for a particular brand... but Sony has earned my respect lately and I have been recommending their phones around me... However this issue has nothing to do with PA being biased (which some of the authors are, particularly when it comes to reviews) and it does not change the fact that Sony makes great innovations, but it does have failures. Like some have said, hopefully this does not extend to the Honami and future devices... I truly want to get a Honami Mini...

It's a software issue, guys. Had that in one software update in my Xperia Z. Calm down, Phonearena. We know that you think Samsung wins and Sony sucks. But it's not.

Problem is problem regardless its big or small, its annoying. Every company has different types of problems. However, unlike Apple, Sony won't say "You hold the phone wrong".

Most likely a software problem!

Sooooo where are the Sony bandwagoners now? With the screen not able to turn on, it's just a big, black rectangle.
