I have an in-house app which we deploy as an apk via a profile.
I have 2 profiles - one for work managed devices and one for work profile devices.
The managed device profile works fine, always installs the app without a hitch.
But for the BYOD (work profile) devices, the app usually doesn't install. I have one successful deployment (after agreeing to the installation of an app from an unknown source) but two other phones refuse.
The devices have a feature control policy in place with "Allow Installation From Unknown Sources" turned on, and, on the devices, I have also allowed apps from unknown sources to be installed by MobiControl.
Nothing seems to work - the app installation request sits in a 'pending state' on the portal for 15 minutes or more, before finally reporting 'failed'.
The log merely states "Package (name) version (version) failed to install. File IO error on device. Check Storage/Permissions.
As a test, I tried downloading the apk using a browser - I then get the message about installing unknown applications and have to authorise the browser to install. This does work, but only helps me a bit, because I won't easily be able to deploy updates using that method.
I'm certain this is a permission issue, but can't figure out what needs changing. These are new device enrolments by the way.
Hope someone can help.
Thank you
James
