Laptop constantly switching between desktop and tablet mode?

Hi, I bought a, Dell Inspiron 7348 Hybrid, Laptop/Tablet, with Windows 10 about 3 months ago, and after about a month of owning it seemed to have a mind of it's own.
However my current problem causing me some gaming grief which is it's tablet mode auto switch.

I'll have my laptop sitting completely flat on the desk and all of a sudden, the keyboard disables and a pop up comes up asking me if I'd like to switch to tablet mode or stay in desktop mode, as if it thought that I had flipped the screen around to a tablet.
It then quickly changes back and forth between desktop and tablet mode which is quite annoying when you're trying to use the keyboard.

Any help to fix this would be greatly appreciated! Cheers in advance!
