I bought both an XperiaZ Smartphone and an XperiaZtablet two weeks ago, and have spent hours and still not succeded in getting online via the G4 connection of the Smartphone. I have read manual, the phoneaccesses the G4 net perfectly on its own, I can connect and transfer files via USB from both tablet and PC/Win7pro, and occasionally these thre units does see each other when scanning- BUT I am unble to access the web !!!!
Your manuals seem to be written typically by persons who drop explaining the detail theyfind "self evident" !!!
Whith the internet availabe You should havestep bystep explanations available for "Dummies" to cn You please send such explanations, or I will just dump the gear and go back tomy old Nokia and slow connections.
