As you'll recall from our hands-on, the Samsung Galaxy S 4 Google Play edition is a dead ringer for its skinned relatives. Unfortunately, this means you're dealing with the same boring design and dreadful materials. Cosmetically, it only differs from T-Mobile's model in one way: there's no carrier branding on the back. It's identical under the hood, and features a Qualcomm 1.9GHz quad-core Snapdragon 600 SoC (APQ8064AB) with 2GB RAM, 16GB of built-in flash with microSD expansion, a gorgeous 5-inch 1,920 x 1,080 (441 ppi) Super AMOLED display, an excellent 13-megapixel camera with LED flash and a removable 2,600mAh Li-polymer battery.
It also boasts the same radios as T-Mobile's handset (unlocked here, obviously) with quad-band GSM / EDGE, quad-band UMTS / HSPA+ up to 42 Mbps (850 / 1700 / 1900 / 2100) and multi-band LTE (700 / 850 / 1700 / 1900 / 2100 / 2600). These bands are compatible with AT&T, and having AWS support for HSPA+ is pretty important if you're a T-Mobile customer in the US (especially in non-LTE markets). In terms of additional connectivity, there's dual-band 802.11a/ac/b/g/n, Bluetooth 4.0 LE, NFC, IR and GPS / A-GPS. Despite being based on T-Mobile's version, this Google Play edition includes the chip needed for Google Wallet, which is great news (the carrier usually blocks the app).
When it comes to performance, the Google Play edition definitely feels snappier than its TouchWiz-equipped counterparts. Clearly, that's subjective since the benchmarks we gathered in the table below almost match what we observed on the skinned models with the same processor. GFXBench scores are slightly higher and the results for Antutu and CF-Bench are marginally lower, but that's about it. Battery life is what really blew us away -- our default rundown test (which involves playing an HD video in a loop with the brightness and volume set to 50 percent; social networks and email checking in over LTE; WiFi and GPS turned on, but disconnected; and Bluetooth disabled) the phone kept on ticking for 11 hours and one minute. That's a significant improvement over T-Mobile's Galaxy S 4, which logged nine hours and 15 minutes. Sound quality was fine during calls and data speeds reached up to 23.5 Mbps down and 21 Mbps up during our network performance tests on both AT&T and T-Mobile in San Francisco and beyond.
The one thing that's always been half-baked with stock Android vs. skinned builds is the default camera app, primarily because of its incredibly basic UI and lackluster image processing. Luckily, things have changed with the Google Play edition handsets, which boast an improved app (1.1.40012 vs. 1.1.40001 on Nexus devices) with visibly better camera performance. Images speak louder than words, and this Galaxy S 4 takes pictures that are just as beautiful as the ones we captured with its TouchWiz-equipped siblings. It's the same story for video recording, with results (1080p / 30 fps / 17 Mbps) matching the skinned versions, complete with stereo sound. The photos we snapped exhibited accurate color balance and exposure, with tons of detail (thanks to the sensor's high resolution) and decent dynamic range. While low-light performance is solid (noise isn't much of an issue), the lack of OIS often results in blurry shots, even with steady hands.
Despite the improvement in imaging quality, the camera UI still suffers from some quirks; the main culprit being the cropped viewfinder, which makes it impossible to frame shots properly regardless of the aspect ratio selected in the settings. It's particularly annoying here because of the sensor's 4:3 aspect ratio. Strangely, the front-facing shooter lacks an HDR mode and the focus reticle only appears when using touch-to-focus or tapping the on-screen shutter button (it normally pops up automatically when the content of the viewfinder changes measurably). The updated camera app now draws the settings menu in an arc instead of a circle, making it easier to operate with one hand. Of course, no TouchWiz means no more Dual Shot, Eraser, Sound and Shot, Drama Shot, Animated Photo and whatever other (arguably forgettable) shooting modes are normally present on the Galaxy S 4. That's all right -- you'll have a blast using Google's cool Photo Sphere instead.
