Can someone suggest me which column in datafeed I need to check for the device type reports (mobile, desktop, tablet)?
Mobile Device Type Reports should not available in Data Feed directly as they should be computed based on Resolutions/Dimensions, User-Agent, Mobile as a device, etc. i.e. Some lookup table provided by Adobe Analytics DeviceAtlas. Due to contractual obligations, Adobe has this DeviceAtlas, so check with Customer Care, they can or cannot disclose, pretty not sure, you can check with them. Earlier they didn't disclose!
