Galaxy s4 smart scroll demo5/7/2023 Perhaps that will still be tweaked in time for the U.S. More often than not it felt like there was lag, or our swipe wasn't registered. In practice, we found the sensors a bit too sensitive, requiring precision and proximity to work smoothly. We tested the gesture navigation in the Gallery app, where we navigated images simply with the forward or backwards swipe of a hand. Through it all, we've heard talk about integrating gestures into smartphones and tablets - and now that becomes a reality in the Galaxy S4. Then gestures moved into televisions and then to PCs, for example Sony's Vaio E-series. Gesture navigation first gained mainstream traction with Microsoft's Xbox Kinect. Among the other display options now available are Dynamic, Standard, Professional Photo (Adobe RGB), and Movie. Ultimately, further testing will be necessary under controlled conditions and with the final, shipping S4 to determine how the different settings impact how images look on the display. In the Note 8.0's reading mode that mode is strictly optimized for reading apps and also adjusts for color temperature. On the S4, the Adapt display feature is more universally applied than on the Galaxy Note 8.0 tablet. This adaptive display setting automatically adjusts the contrast and brightness of the display depending upon the content you're viewing, optimizing based on whether you're watching a video, looking at an image, or reading a Web page or book, for example. With the new Adapt display mode enabled, the differences were even more pronounced. The new Adapt Display function automatically adapts screen contrast and brightness to the content you are viewing. The Note II's image appeared slightly sharper, but the S4 had more balanced skin tones. We noticed some minor differences in color and sharpness on our own photo. Indeed, we saw this when viewing a photo on the new S4 compared with the Note II. It also accounts for the display not appearing as crisp as an RGB display, such as the one found on the Galaxy Note II. A PenTile display arranges the display's subpixels as red, green, blue, green, an arrangement that helps counter the fact that blue subpixels often degrade faster on AMOLED displays. The new model uses a PenTile AMOLED display, the same type as on the S3 before it. But the distinctions were less clear when compared with the larger Galaxy Note II. We could see a distinct difference in the image quality between the two: The S4 looked sharper and crisper to our eyes, on text as well as images. The resolution is better, too: 1920-by-1080 pixels, and 441 pixels per inch, a notable step up over the Galaxy S3's Super AMOLED 1280-by-720 pixels and 306 ppi. The phone's Super AMOLED screen measures a comfortable 5.0 inches, a satisfying 0.2-inch bump over the S3. One very noticeable dfference is the larger screen size on the S4. The back remains a polycarbonate plastic material, but it felt more sturdy than the predecessor, with a slight textured patterning that gave the phone a moderately classier look. The phone's design is a little more squared off around the sides than the S3, but it still felt good in our hands. It's weight and dimensions make it light enough to hold in one hand without any noticeable impact, yet large enough to get a satisfying display of text and photos. Where the Samsung Galaxy Note II is nigh impossible to balance in one hand for typing, not so with the S4. Overall, the phone felt comfortable to handle. The S4 is also very marginally lighter than the S3. The S4 measures 13.5 by 7cm (5.38 by 2.74 in), just 1mm (0.04 in) narrower than the S3 - and a notable 11mm (0.43 in) narrower than the Galaxy Note II. The first thing to note about the S4 is that it's practically identical in footprint and weight to its predecessor, and yet it's thinner and crams a slightly larger display into that space than on the S3.

We went hands-on with the S4 at the New York event, and came away impressed with the innovative and well-integrated software and hardware enhancements that will keep Samsung well-ahead of its competition.įor more information and detailed specs also read our launch article. But that's not the case with the Galaxy S4. Often, such over-the-top theatrics could mask a lack of substance underneath. Samsung launched its flagship Galaxy S4 smartphone to much pomp and spectacle last night at Radio City Music Hall in New York. The Samsung Galaxy S4's design is very similar to its predecessor, the Galaxy S3.
