If the compass is still not working correctly after calibration, then service would be recommended for the phone for an evaluation. You can use the following link to find a list of service centers in the U.S. that can do the repair: http://www.samsung.com/us/support/service/location or by calling customer support at 1-800-726-7864. For service outside of the U.S., please use this link: https://www.samsung.com/us/common/visitlocationsite.html I do apologize for any inconvenience.
