Background: Working with SharePoint one additional device channel, i include Phone, Android and "Tab" in inclusion rule for mobiles and tablets, everything was working as expected.
Problem When one user try to access from its "Dell all in one PC". In IE: it shows the mobile version instead of desktop version and when try to access using Mozila, it gives expected result that was default version of SharePoint master page.
Question: Now how to differentiate that the request coming from "tablet" or "dell all in one PC". Because both are touch screen but "dell all in one PC" is a big screen and mostly used as desktop not tablet. and i need to show the desktop version of master page on "dell all in one PC" not tablet version
For information User String is below from Dell all in one PC: Mozilla/5.0 (Windows NT 6.3; WOW64; Trident/7.0; Touch; rv:11.0) like Gecko It has the word touch that force sharepoint to open tablet version from device channel.
