Current in the tablet arena we have a 2 horse race. It's either Android or iOS and anything else is in the sub percent category that you won't get apps like Angry Birds on Pokemon Go.
Remember I'm going to take your word it's their OS and not some Android with a skin.
I have heard a lot about Vivo phones. Regardless of hardware, I would like to know if its Funtouch OS can compete with iOS?
