Maximizing Video Playback on the Nokia E63 The remains one of the most reliable legacy QWERTY devices ever made. While it was designed primarily as a messaging and business phone, the device features a surprisingly capable landscape screen and a dedicated 3.5 mm audio jack.

If you drag and drop a standard YouTube downloaded MP4 (640x360 or higher) directly onto your E63 via USB, it will not work . You will see the dreaded error: “Unable to play video. File format not supported.”

A user attempting to drag-and-drop a standard 700MB AVI file ripped from a DVD would encounter an error stating "Unable to play media clip." This created a distinct ecosystem of workarounds.
