I have the DOOGEE DG310 smartphone now for 8 weeks in operation and I must say, you can not expect more for the money. It makes a high quality impression and looks forward to the Samsung S5 confusingly similar. The smartphone has Antroid 4.4.2 on board and a relatively large internal memory, which can be extended with a memory card to 32GB. The dispaly is absolutely ok for this price range, despite the small 854x480 pixel with quite sharp and contrasting colors. What I find particularly great is the Dual Sim mode. Now I can use my two SIM cards (Call Mobile and Club network) simultaneously in one device. The DOOGEE DG310 runs fast and absolutely smooth, I could not tell when my LG Smartphone before. The mobile browsing thus makes both Wi-Fi and two radio networks (O2 and D1) a lot of fun. Clear you have to make compromises. The camera is useless because the phone creates not to shoot a reasonably sharp image even in sunlight. The battery life could be a little longer, with intensive use of this Smartphone is after 10-12 hours empty. Another drawback, at least for me: It was probably saved when gluing the display something on the glue, because at the bottom right corner of the display has solved something. So far does not bother really, is more of a visual problem. As I said, at the price but everything bearable. I would buy it in any case again.
