The Samsung Galaxy S4 is not getting rave reviews. Walt Mossberg, the most influential gadget review on the planet, has a relatively harsh review of the S4. Mossberg's reviews are generally subtle, and balanced. His S4 review is fairly direct: I’ve been testing the Galaxy S 4 intensively for four days and while I admire some of its features, overall, it isn’t a game-changer. It’s an evolution of the prior model and despite some improvements, it still is especially weak in the software Samsung adds to basic Android. I found Samsung’s software often gimmicky, duplicative of standard Android apps, or, in some cases, only intermittently functional. I urge readers looking for a new Android smartphone to carefully consider the more polished-looking, and quite capable, HTC One, rather than defaulting to the latest Samsung. After a quick read of a few other reviews, this seems to be the consensus on the S4. Nice phone, but not nearly the killer you would expect consider...
