manojviduranga Hi, what did you add before re-encoding the QR code? The full code for keeping the system apps is "android.app.extra.PROVISIONING_LEAVE_ALL_SYSTEM_APPS_ENABLED":true
Your full code should look something like this: (I removed the checksum and enrollment token for obvious reasons)
{"android.app.extra.PROVISIONING_DEVICE_ADMIN_COMPONENT_NAME":"com.google.android.apps.work.clouddpc/.receivers.CloudDeviceAdminReceiver","android.app.extra.PROVISIONING_DEVICE_ADMIN_SIGNATURE_CHECKSUM":"........","android.app.extra.PROVISIONING_DEVICE_ADMIN_PACKAGE_DOWNLOAD_LOCATION":"https://play.google.com/managed/downloadManagingApp?identifier=setup","android.app.extra.PROVISIONING_LEAVE_ALL_SYSTEM_APPS_ENABLED":true,"android.app.extra.PROVISIONING_ADMIN_EXTRAS_BUNDLE":{"com.google.android.apps.work.clouddpc.EXTRA_ENROLLMENT_TOKEN":"........"}}
Hope that helps
