Device channels were introduced in SharePoint 2013. Device channel allows us to map the created device channel to a device, based on its user agent and target custom master pages, specifically to the device. Thus, we can have one master page for iPhone while a different one for Blackberry and so on.

However, when we try to specify a master page for the device channel, we will get the below warning if Mobile Browser view is not disabled.

We can disable Mobile Browser View feature across the sites in a site collection by running the below script in SharePoint 2016 Management Shell.
  1. $SPWebApplication = Get - SPWebApplication - Identity "http://SharePoint2016"
  2. $SPSiteCollection = $SPWebApplication | Get - SPSite - limit all
  3. foreach($SPSite in $SPSiteCollection) {
  4. $SPWebs = $SPSite | Get - SPweb - limit all
  5. foreach($SPWeb in $SPWebs) {
  6. Disable - SPFeature - Identity "d95c97f3-e528-4da2-ae9f-32b3535fbb59" - url $SPWeb.URL - Confirm: $False - ErrorAction SilentlyContinue
  7. }
  8. }

Now, we can successfully specify the master page for device channel, as shown below.
