There are many improvements in this upgrade for your Xperia™ smartphone, some examples are:
My battery life is still and absolute joke. I used to rave about my Xperia Z - now it's not on for long enough to make me want to keep it. PLEASE - get my battery life back to what it was before this stupid Kit-Kat update. You have ruined my Sony experience.
@Dawoodyyou can take a screenshot by pressing volume down and the on/off button together (as on every android).
Less memory usage compared to the previous version. But why is the video sound bug still there!!!??? after so many updates... real hopeless devs or the devs are silently protesting that they are not paid enough for their work 
i'v had my fon for only 9 moths now, and i'm having a lot of problems even from the beginning.
at first it keeps on restarting on it's own, so d store installed new software and it was fixed.
then during d last couple months my fon was working soooo slowwwww!
it lags most of the time.
my fon is not so much loaded with apps or anything so i don't know why it's so slow.
then now the keyboard keeps closing and sometimes it doesn't show up when i need to type esp when i'm using facebook app.
i hope it works better after this update.
you can still take a screenshot by pressing the volume key and power key at the same time.
