With its beautiful display and stylish design, the Samsung Galaxy S III looks great on the outside. But, what about on the inside? And how does it compare to the Galaxy S and Galaxy S II. Let's crack it open and find out.
Our T-Mobile test unit had a 1.5GHz Qualcomm Snapdragon S4 processor, 2GB of RAM, 16GB of onboard storage (expandable via the microSD slot), a 4.8" HD Super AMOLED display (1280 x 720 resolution), an 8-megapixel rear-facing camera, and a 1.9-megapixel front-facing camera. It measures 5.38" (H) x 2.78" (W) x 0.34" (D) and weighs 4.7 ounces.Full teardown gallery: Cracking Open the Samsung Galaxy S III (T-Mobile)
Cracking Open observations
- Easy-to-open case: On the plus side, its polycarbonate case is ridiculously easy to open. Thanks to its user-replaceable, NFC-capable battery, the back cover just pops off. And after removing a few Phillips screws, I detached the motherboard cover using just my fingers. The headphone jack and speaker assembly came out just as easily.
- Easy-to-remove motherboard: Another positive is the motherboard's connector placement. Unlike the HTC One X, most of the S III's connectors are located on the side of the motherboard that faces the phone's back cover. This makes the board easy to remove and reinstall.
Unfortunately, while getting to the internal components is easy, replacing them may be a bit more complicated.
- Clustered components: Some components (such as the volume buttons, earpiece, and service light) appear to be joined together with a single ribbon cable. If you replace one, you'll need to replace them all.
- Cables glued to internal frame: Most of the internal ribbon cables are glued to the internal frame. If you ever needed to replace the frame, it would very difficult to remove all the attached components without damaging them.
- Fused front panel/display/frame: Why would you ever need to replace the frame? That question brings me to my biggest complaint about the phone's construction. The front panel, display, and frame are all sandwiched together and held in place with extremely strong adhesive. If you crack the display or front panel (which happens a lot), you'll likely need to replace the whole assembly or just get a new phone.
As of this tapping, T-Mobile's version of the Samsung Galaxy S III is available for $279 (with a two-year contract and after a $50 rebate). And despite my complaints about repairability, the S III is a solid Android phone with top-shelf hardware and a highly-competitive price.For more information on the phone's software, real-world performance, and battery life test results, check out Jessica Dolcourt's full CNET review.
