HOW TO KNOW ORIGINAL PHONE AND A FAKE PHONE 

Before you buy a new phone dial *#06#, it will display the serial number or IMEI number which must be 15 digits and must begin with 35. Now check whether the number displayed is the same with the number on the battery base. If it's original the numbers would be the same, if fake the numbers would be different. You can check your phone right now to know whether you are using original phone or fake phone.
