Allwinner android tablet - DEMO appears on screen

[Jas Colder]

Hi

I have purchased a allwinner android tablet and when I turn it on. The word DEMO is appearing in the bottom left corner of the screen. and remains there what ever I do.
It is not affecting the device and applications but I don't know how to remove the word DEMO.

Can any one help please.
Thanks
