I bought one of these Doogee phones (through Amazon) and it worked ok for about a month only to then to find that they shipped with dodgy malware apps installed. The malware starts to re-direct your browser to other website and pop up ads. Doogee tried to blame it on apps that I had downloaded myself but I have exactly the same apps on my tablet and do not receive any pop ups on there. Many other users reported this on the forums of the Doogee website but they just ignore the complaints and offer no fixes. Would not buy another Doogee phone again because of it, even though the phone hardware is actually pretty good for the price you pay, and that is the only reason i have not given them 1 star
