Software Update

I have recently updated my Z1 to 4.4.2 14.3.A.0.757 via PC Companion. I am getting a feel that my phone has become slow . . . After Screen when I go back to Home Screen (Main) I feel a short lag, also after disconnecting call once the phone is locked if I unlock some time Camera is open and it doesn't respond to back key. I have to use other key to close the app to go back to home screen.

If some one can help it will be great.

I have the same error that sometimes "back" button doesn't work when in camera. Especially when you are using other modes, switching between them, suddenly "back" button doesn't work and you have to use "home" button 😕

Also, the mode icons in camera lags, tend to appear very slow

You're not alone.

I tried to check the amount of availability of RAM, its showing 880 MB as Free RAM. I Have not downloaded even a single app in my phone. There was one error I couild recall while I was udating the software.

When I first conneced my phone to PC during the 40% buffring internet connection was down and then when connection was up it again started from where it was stopped but once I again connected the phone for final update there was no issue.

Is this can be an reason ?? Was there any issue when you updated the phone for latest software ??
