Enterprise Firmware Over the Air (E-FOTA) is a service provided by Samsung used to update software on Samsung enterprise devices. This mechanism when synched with SureMDM helps admins push the latest software and firmware updates on the devices remotely.
This feature can also be helpful is Samsung devices are enrolled to SureMDM without being enrolled to E-FOTA. Admin can still link SureMDM to E-FOTA using the below steps. Once done, the device will be able to receive latest firmware and software updates.
