I just ordered my HTC One, haven't tried out the S4 but I heard it wasn't all that great basically an S3S kinda like what Apple does with iPhones and the 4S and stuff. Also I had an S2 and trying to get away from Samsung the build of my S2 was crappy from day one, extremely light and flimsy and after just a month the corners had cracked. And the S4 is the same construction! Assignment Writing Service UkAlso the HTC One has gotten AMAZING reviews and is being called the best phone of 2016! I would go for the One its got a better build, looks WAY better, has a better screen with more pixels!
