on my previous sony ericsson phones im able to click a button and see how many percentage of battery left,
how do i do the same on vivaz pro ,
***Edited to add labels***
Used the NeoCode app to scan the neocode here: Battery App
You'll download it, go to your file manager, under download (probably on your memory card), and run the install app.
By default, your phone will try to open the .wga file in notepad view. I don't know why. But if you click on it via file manager, your vivaz will know to install it.
I don't know why sony strayed from its rocker switch behaviour. But, here's a nokia workaround.
