Not recommended to buy vivopad. I already bought and found there is no default apps setting and those default apps are hardcoded to use their own made apps. That mean if you click a link, it will open vivo browser (you may have security concern) even you installed google chrome. Same thing that it's home screen design is ugly and no option to set # of row/column. Even you install a 3rd party home screen launcher, the pad will still jump back to it's ugly home screen every time you press HOME button.
