How to enable thumb keyboard?

[itsmrdon]

Hi Guys,

I just bought Advan W80 with Windows 8.1 and I am wondering how to enable the thumb keyboard? I have tried to tap the keyboard layout option on the bottom right corner, but the thumb keyboard is un-tap-able, but the rest is tap-able.

Seems like to thumb keyboard is disabled for some reasons. Anybody can help me with this matter?

Thank you.
