Welcome to Knox E-FOTA

Welcome to Knox E-FOTA, a web service that lets you manage the Android firmware versions on Samsung devices. It allows you to do the following:

  • Verify that business-critical software is compatible with a specific firmware version before rolling out the firmware to employees. This can prevent conflicts between corporate software and firmware that can break business processes and reduce productivity.
  • Quickly roll out to all enterprise devices a firmware version that fixes a critical security issue or bug. This can prevent the propagation of known security exploits.

This guide provides information on how to set up, configure, and use Knox E-FOTA.


This guide is intended for a wide range of developers who want to manage device firmware.
