Samsung is today introducing the Galaxy Note 4, a large new smartphone that sticks to the formula of the Note 3 while rounding out many of its predecessors rough edges. The Note 4 looks very familiar, but thats not a bad thing: Samsung has been iterating on its wildly successful phablet for four years now, and that means its had plenty of time to improve upon its weak points. With Apple reported to be announcing a large, 5.5-inch iPhone just a week from now, its critical that Samsung make this new Note as appealing as ever. One of the notable additions to the Note 4 is a metal band wrapping around its side, much like the recent Galaxy Alpha.
