Since it's just few weeks old, I hope you do get a replacement.
For the sake of it I have completed a thorough reinstall of android 4.4.4 doing a full wipe (data, system, dalvik, cache), checking the md5 and following the method described here (http://forum.xda-developers.com/goog...image-t2513701
) but it had no effect at all.
I start thinking that the issue might material in the end and that my best shot is trying to get it replaced.
If somebody has another idea, I am willing to try it.
