The Samsung Galaxy S4 has arrived to America, and if you have been eagerly waiting to know how it feels to use the Galaxy S4 in the real world, the wait is over. Since its predecessor sold more than 50M units worldwide, the Samsung Galaxy S4 has to live up to rather high anticipation and expectations. You may have followed our first hands-on review of the S4, so you may know a fair amount about this smartphone. for this complete review, we have had more time to use the Galaxy S4 as a primary smartphone, and needless to say that on paper, it improves upon all aspects of the Galaxy S3 with which you may have seen or played with. If not, don’t worry, we’ll provide a good picture of what the S4 is. Now, the question is: how does it actually behave in the real world, and is it a smartphone for you? Samsung Galaxy S4 Specs (powerful) First of all, let’s go over some critical specifications of this new smartphone (a Sprint unit), just to have a frame of reference: Galaxy S3 iPhone 5 Galaxy S4 HTC One Weight 133 112 130 143 Display Size 4.8 4 4.99 4.7 Resolution 1280×720 1136×640 1920×1080 1920×1080 Pixel Density 306 326 441 468 microSD 64GB max No 64GB max No OS Android 4.1 iOS 6 Android 4.2 Android 4.1 Battery mAh 2100 1440 2600 2300 Battery removable Yes No Yes No Infrared blaster No No Yes Yes Camera (F) MP 1.9 1.2 2 2.1 Camera (B) MP 8 8 13 4 Thickness (inches) 0.34 0.3 0.31 0.37 Note that there are a few variants of the Samsung Galaxy S4: this one is powered by a Qualcomm Snapdragon 600 quad-core processor at 1.9GHz, but the two others feature a Samsung Exynos Octa 5 4+4 cores that I have described at length in my Exynos Octa 5 post. The Samsung chip may embed 8 cores, but it should be considered to be a quad-core chip (in code execution terms) since only 4 can run at any given time. Samsung used the big.LITTLE architecture from ARM, and if you are curious, check what I think of big.LITTLE, it’s pretty neat. Update: experts say that the GS4 is also “easy” to repair. Many of you have asked “why” Samsung comes up with these hardware variations, and although none of the companies involved would usually comment on this hot topic, my guess is that carrier certifications end up being what’s driving those choices. Since the Qualcomm communications software stack works obviously much better with their own processor/modem combo, and given that US carriers (AT&T in particular) have tested and approved Qualcomm, it’s likely that Samsung has chosen Qualcomm to have a faster time to market (Samsung may not have time to qualify their own chips) in order to hit a worldwide market at launch. Although you may hear a lot of noise about the hardware differences, the user experience of both platforms is largely comparable. That’s my opinion after playing with an “Exynos version” of the S4 recently. Context We all use our phones differently, so it’s important that I tell you what I do with my smartphone(s): I typically check email often with the built-in email app (via Microsoft Exchange), and reply moderately because typing on the virtual keyboard is tedious. I browse the web several times a day to check on news sites, but rarely watch movies or play music. I don’t call much – maybe 10mn a day, if at all. On the “apps” side, I have a couple of social networks (FB, G+), a receipts manager and random apps (<20), but I rarely play games or do something super-intensive like video editing. This usage pattern will affect battery life and the perception of what features are useful. Now you know where we’re coming from…
