Regional Phone Settings Help (Galaxy Note II)

[agoodfella]

Hello folks,

Just a quick (and probably dumb) one:

I recently upgraded my Galaxy Note II to JB 4.1.2. I noticed that my phone input (when dialing numbers) goes from the standard (I am in Singapore):

XXXX-XXXX

to now : XXX-XX-XX

Is there anyway to change this back?

I've been searching high and low but no luck.

Many thanks!
