I have this bug when I updated it, when I press the sound button the sound bar comes up on the screen but when I press it again while it is still on the screen it doesn't go up it freezes but you can hear the sound getting louder on the phone, I have to wait till it fades away then press it because then on the sound bar it wouldn't go up. FIX THIS SONY!!!!!!!!!!!

Did you you just do an update on your phone without formatting the phone's memory? if you didnt do that then i suggest you do as i had the same problems some options were not working etc...

                        I am having about 99% of the problems above since I updated my z1. Used to love my phone, now it's just becoming a pain to have. Missing calls, overheating, flashing settings icons in the top left screen, and many more. This is ridiy

                              Look and Feel of 4.4.2 kitkat update is superb but performance wise its not upto the mark.Over heating,Battery draining, Hanging of phone are there.Somehow sound problem is resolved by .757 update. Antutu Benchmark test Results show drastic reduction in performance,35000 to 31000 overall.Plz wait for better update and then update.

                                Do not upgrade to the new version of android 4.4.2 as there as so omany pronlems with it. The phone overheats, battery drains 80% quicker there are sound issues and very slow charging. I have the lates version which is 757. If I could downgrade back to jellybean without losing the Information on my phone I would. Kitkat is a horrible mistake.

                                    Same here as for many others. My camera got broken in the update. Really slow, random crashes and at times not even able to take pictures at all. Services such as Instagram is almost unusable.

                                    My operator is Telia Sweden.

                                        I'm living in Iran,obviously when I connected to Sony Pc Companion as I wanted to update my phone(Z1), it says: there is an update available which number is 14.3.a.0.757 is available for my Z1.However after preparing the device to receive the update another notification comes afterwards which says:there is no available update four your device at the moment!!!I cant understand what is wrong with Sony after all this mess ups with the new firmware.I am just waiting until Sony fix all of these related bugs in short period of a time.
