The Galaxy S4 is a S3's improved version in almost every way, while HTC One X+ comes with the advantage of being made from premium high quality materials, thus beeing much better than those used by the South Korean company and having a great design interface.
For starters let's analyze the hardware of the two competing smartphones. In this regard, Samsung has made significant improvements to this model, compared with last year version, it has an amazing full HD 5 inches displya with a resolution of 1080p, plastic casing with aluminum tapes on the edges, which gives it a premium look, thus eliminating most criticism received by the south corean company for preferring plastic cases for its devices.
A 1.9 GHz quad core Snapdragon 600 processor for the american buyers or a 1.7 GHz Exynos 5 octa core processor for the other parts of the world, 2 GB of RAM, a 2 Mpx front camera or 13 Mpx rear camera, an amazing 2600 mAh battery and more special and unique features like: 5G Wi-Fi, supersensitive screen, gesture sensor, Gorilla Glass 3, RGB light sensor, noise calcellation, hydrometer, thermometer, barometer, MHLS, high-performance audio chips, Tripadviser, assistant for emergency situations, Photo Cinema, Group play, Gaming Group, Cinema Photo, Shot Eraser, Photo Reader, Story Album, Air View, S Translator, S Heath, Smart Pause, Smart Scroll, Air Gesture, Smart Call Accept, etc., these are just few of special and unique features that make this smartphone a top high-performance device with broad applicability for the various categories of buyers.
Here are some of the highlights from the One X+ : a battery with a longer lifetime, storage capacity up to 64 GB, a processor up to 67% faster, a 1.7 GHz quad core processor, integrated Beats audio, modern design, clean and well-defined lines, made only from high quality materials, nice looking, light, sophisticated, very easy to handle even with one hand, which can be useful in many situations, a 4.7 inches display, 2100 mAh battery, a very high sound quality, these are just few of his features that makes from this smartphone a strong competitor fot the south korean models.
The phone is much easier to hold in your hand or to handle with only one hand, but at this chapter HTC One X + is the winner, because it is thinner and lighter than S4. HTC'interface is better structured, while Samsung does not excel at this, and I personally think that inspiration from nature does not seem appropriate nor sophisticated impression.
My opinion is that each of the two smartphones meet the needs of customers to the highest standards, both benefiting from improved Android operating systems with diverse features, although both smartphones are powerful rivals who are on a broad level, however should keep in mind that each is an unique smartphone, but Samsung Galaxy S4 yet brought the newest innovations in software technology market compared to any other smartphone invented till it.
