Hi everyone. I recently purchased the Z1 direct from Sony, running on Android 4.2. I used to have the option in the network mode settings for 4G, as well as in the quick settings at the top of the notification bar. Unfortunately, after updating to 4.3 I noticed that this option appears to have vanished from both menus and I can no longer find anything to do with 4G anywhere on the phone. I have tried updating the APN settings (both automatically and manually) and it still is not there. I have been in a supposedly 4G area earlier today and saw no sign of any 4G signal (or any signal for that matter, but that appears to be lousy network coverage in the area). Has anybody else noticed this, or am I just being a bit thick?
