Hi , I am using a Samsung Galaxy Grand GT-I9082 Android version - 4.2.2 I am unable to find the MTP file transfer option , the moment i connect my phone to PC via usb it starts charging . But the option of mass storage is not found. I tried with my Samsung S3 and Samsung S Duos it works well but only Samsung Galaxy Grand GT-I9082 has this issue. Kindly give me your expert advice. Waiting for your reply.
