Chinese telephones....Google is banned China and so Androids here don't have it, and a Chinese vendor may not know much about it either. To make Google work on one of these things, you might have to root it, flash a custom recovery, and then flash Google apps package as system, and for the Weiimi there's no information on this whatsoever. Their site is only in Chinese,
and they're not selling internationally, so no information about Google on there. http://www.weiimi.com/ (Chinese only) Send it back for a refund is my best advice. Same with the Coolpad, that's only sold in China, so there's no information about that one either.
Some Chinese phones it's quite easy to install Google and there's plenty of information available in English, which are Oppo, Meizu, Xiaomi, Vivo, Koobee and Gionee that I know of. And they do international versions of some of their phones that already have Google on them.
