To enable US Android native call recordings on your Android Samsung device you may be required to flash (installing a new software, mostly operating system) your phone’s ROM with a version identified with a non-US country code. After you perform this modification, you will be able to record voice calls (as well as SMS/MMS) using the TeleMessage Android Archiver. Adjust your Country Specific Code (CSC) as per the following procedure.
Watch this video, or follow the instructions below the video.
- You must have sufficient technical understanding to make a system flash hack to change your phone’s CSC.
