Hi, Im using xperia z c6603 but in my sony PC companion it says that my phone is up to date and there is no firmware available yet. so the jb 4.2.2 is still not available for xperia z c6603?

New updates makes my ZL more faster than before. Some bugs are solved and works nice. Happy with the new updates of BN : 10.3.1.A.0.244. My problems are solved. Tnx to Sony. But waiting for Jelly bean 4.3 :)....after updating, users who have still the problems, it can be said that your device's hardware have problem. replace it.

Does the firmware impart any significant improvement in camera's performance? Which one out of the three (Z, ZL and ZR) performs the best AFTER the update in the camera and display departments?

.244 uk update Sucks here because

1. Picture quality gone really bad, too much grain and when you use superior auto. when you take picture and zoom in grains are well noticeable and makes picture look bad even on 12mp

2. night time picture really sucks because of really annoying grins all over the screen

3. battery never reaches to 100%, stays on 99% and drains even quicker

4. quick launcher is slow

i'm rolling back to old one ...not happy
will wait for next update hopefully it will be fixed

also, from where did you bought it ? if from Sony World try to find the problem from your PC ( that's what I'm thinking of ). if problem still not fixed, just go to Sony maintenance branch.

by the way, I love all Sony products.
