Sony, solve your yellow hue issue on your Triluminos display in Xperia Z1.
Update all Xperia devices to KitKat 4.4.2.
This is nothing surprising, the only problem is consumers that are felt with "old" flagship phones within few months of purchase. Put all those new mobile technologies you've been working on in your secret labs in phones now instead of putting few of them in each flagship phone. We've heard of SD805 but compaines keep playing with 801a,801b,801c,802a,802b.........blah blah blah
