Next patch version for the Z is still 4.1.2 but has some optimizations, let me name a few:
- Soft keys + notification bar background changed, it is now black and looks a lot better.
- There is an option to adjust the white balance of the screen
- There is an options to enable/disable the notification light
- Stamina seems to work much better, better standby time plus LED notification works with stamina on. Also noticed that apps in stamina exception list work much better now.
- WiFi reception is MUCH better.
- Camera opens faster than before, still a bit slow for my taste but it is a step to the right direction.
- The device is faster in general. Have tested this with another not updated device and it is in the scale of ms but still it is faster and more responsive.
I might be missing a few things here but it is a nice patch, I know it is not 4.2 but still it is a good patch.
Accepting questions to test things but I can't always answer very fast.
EDIT: forgot to write that the exploit for root doesn't work anymore.
