Dear Sir, I am using various models of samsung mobiles since 2008 and i had enjoyed alot the inbuilt GPS Navigation facility in my earlier used android cell phones. I have purchased brand new SAMSUNG GALAXY S4 in the month of July 2013 but dont have the facility of Inbuilt GPS NAVIGATON. Since then i approached so many showrooms and servide centres to get the perticular software (with blue colour arrow default Gps Navigation of samsung). I hope upgrade versions might have additional facilities but not reduce the facilities. Hence i request you to please respond positively and solve my problem or guide me to get so to enable me to continue with samsung. Thanking you...
