Ya, I buy Xperia Z as I seen Xperia V display before but Xperia Z let me down, it is a bit washed out and too dull, less contrast and etc.

But after updates of latest .253 firmware, I am pretty sure Xperia Z display now is equal / better than Xperia V. Everything is in correct way now, much vividness, better contrast, deep black, much sharpen and perfect white balance.

It is too obvious where everyone that had update it will notice it.

.253 is official long long long long ago for Z and ZL. Some user even received .307 and I am running leak .407 base on 4.2.2 now.

You quota my .253 post asking for 4.2.2? who will know?   

4.2.2 is leak, not official.

And here seems is ZR thread not Z or ZL.
