Long press is not working on my cube iwork8 tablet

Hello, I purchased a cube iwork8 tablet, I got that because I wanted a cheap dual OS ( Windows 8.1 / Android ) tablet, everything works great and the performance is just right but it seems I can't long press anything.
For example when I long press a button on my keyboard the pop up menu that displays all available options renders for 1 - 2 seconds before disappearing, it's like my screen registers another touch that makes the pop up menu close.
I think it's a hardware problem, but I thought I should ask here first in case someone had this problem and solved it with a software solution.

Thank you
