I've always been a fan of sony ericsson phones, so when the time came that I wanted a touchscreen phone, sony was the way I went.

The vivaz is alright aesthetically, its a decent shape to fit in your jeans pocket, its not too heavy, nor is it too flimsy, i've dropped mine a few times and have only chipped the outer coating with no other real damage.

The camera isn't great, and the supposed HD video recording, is slow and stutter-y and altogether useless.

Features wise... it fails miserably, there are few apps available that work with the vivaz, and those that do, especially facebook can cause the phone to very annoyingly beep for no reason every minute or so (which it turns out is the app trying to connect through an internet connection that isn't always there)

There are many inherrant faults with the phone, a quick google search will show many with the same problems, very limited connection, slow internet, very quiet when on calls.

And the most annoying... a fault with the touchscreen.

Often reffered to as exorcist fault or phone possession, this is where the phone, seemingly on its own, selects links, presses keys, and does a number of other things all by itself.

Its actually a touchscreen fault, this is very annoying when the phone is connecting to the internet, calling people and sending texts without your permission.
Therefore using your allowance, credit, minutes / texts etc.

It got to the point with my phone, I couldn't even use it, because it was too busy doing its own thing.

in my opinion, sony ericsson has let me down, and itself down, and the vivaz is a blight on sony's record that is best forgotten
