devicetype 5 means Tablet

When to send it

Send 5 when the device is a tablet. Like 4, it arrived in OpenRTB 2.2 to replace the catch-all 1 for sellers that know the form factor. Tablet app traffic and tablet browsers both belong here.

Buyers often price tablet inventory between phone and desktop, and some use tablet-specific creative sizes. Confusion comes from two directions: generic mobile code paths that send 1 for every handheld, and tablet browsers that present a desktop user agent by default, which can push tablet traffic into 2 when the value is derived from the user agent.
