Reading Samsung Health records requires Samsung Health on the phone and records to read. For studies using Health Connect, check both data sharing by the source app and DTRAC's read permissions.
Starting a study

studyIdandparticipantIdidentify the owner of data and remote uploads. - Check permissions and background operation.
