I have discourage everybody to buyelectronics and in particular mobile phones on Aliexpress, no matter how attractive the prices seem to be. Most shops send the phones with a PIN code that you only get when you leave a 5-star rating. This makes the whole rating system worthless and the observant shopper on Aliexpress will also see that almost all shops have a very high rating.
In my case the phone immediately had a defect (stripes in the picture) and the phone went dead after a two months. Return took nearly 60 euro and since I sent it, there is no response anymoret. The returning process (RMA) is not supported by Aliexpress. If I'm lucky I might still get another phone sent again one more time, but I probably should pay to Customs (import duty and VAT) again. That cheap phone is suddenly not so cheap... and also the replacement phone will of the same poor quality... Don't do it!
