One rumor is that the Samsung Galaxy Note 3 will feature a new design, possibly with metal instead of plastic. This rumor popped up in mid-April, though some claim it was put into place by HTC as a move to bolster the metal design of the HTC One. While early rumors claim this design is Galaxy S4 influenced, it is talking about a metal Galaxy S4 prototype that never made it to mass production.
