After android of course heaven and earth. There is a lot of memory, everything flies. I am satisfied with the phone in general. Except for the appearance of trouble with the camera, although I practically do not use it, the phone is still not for 10k. I called the support service, they say, well, bring it to the store (the seller is in Hong Kong, I'm in St. Petersburg) or send it by mail / sdek (yeah, the phone for 80k is unclear where and to whom).
