That's definitely an off-brand Chinese phone. Malfunctioning software can be a frequent issue with them, due to poor quality and lack of testing. Many phones that come directly from China don't have Google services on them, or sometimes they're added added/hacked by whomever and frequently don't work properly. Likely why it's giving the invalid user ID thing. You could try factory resetting it. But if that doesn't work, you'll have to RMA it for a refund.
