How to remove hyphen between the numbers on Samsung Galaxy S2
 

I bought samsung galaxy S2, but i have a problem when dialing or receiving calls,
if the number is 12345678, the number displayed in Contacts and Dialer will be 123-456-78 (where 2 dashes "hyphen" will be added automatically).
Actually, I've checked the number in gmail contacts, and the number was entered as 12345678 without any formatting characters
from some google search . i found that i need to add the English(Lebanon) to language list, and it will fix the issue.
Does anyone know how to add it to the language list, or of there another solution please share in this post
Thank you

Thank you, it's working :)

Thank you! I thought that this feature is a phone-related one, now it's solved :D
