I had the same problem and received the following message from Avast when I raised a support ticket with them:

Thank you for contacting Avast. Unfortunately the “We are sorry, but detailed information for device SM-G935F is currently not available.” is a known bug that sometimes appears on devices running Android 6. For an unknown reason the info sometimes cannot be obtained right - what results into the error. We are investigating the problem but unfortunately for now we got no workaround nor solution for it, my apologies.

I am really sorry for such unpleasant message. If you wish, I can eventually contact you back once a solution will be available.
