As an ICT professional, Incorporated Engineer, I have to say that this is the worst tablet I have had the misfortune to have come across. The dual boot function is badly engineered, it has multiple problems running windows 10 and encounters major glitches whilst running both Android and Windows applications. It is far to difficult to change the language from chinese?/Korean to English and is abundantly lacking in technical support. Stay well away from this device. It is nothing but a headache!!!
