Upset Review by Ashley
Well I was very satisfied with this phone I've dropped it numerous of times never broke. But just recently the phones battery would die quick I go to turn phone on and no matter what I would do it would not go past the metro PCs screen I tried factory resetting, I called metro they an their test on it and told me to bring it in to metro PCs store so that's what I did in which there was nothing they could so besides sell e a new phone and give me ZTE customer service phone number. In which I called but no luck. And I missed a lot of business calls because of phone problem along with I had to dish out more money for a new phone. (Posted on 7/6/2016)
