Obi Worldphone SF1 16GB

Dimensions: 146 x 74 x 8.0 mmWeight: 147 grams

Size: 5.0 InchResolution: Full HD (1080 x 1920 pixels)Display Type: IPS LCDPixel Density: 441 ppiThe Obi WorldPhone SF1 uses a 5-inch screen from Japan Display Inc., which bears a resolution of 1,920 x 1,080 pixels. With the pixel density of 441ppi, the display offers crisp text and images, and colours also remain vibrant. Viewing angles are decent, and brightness also appears to be fine – at least indoors. However, the screen becomes almost illegible outdoors under harsh sunlight.Taking care of the display against scratches is the latest version of Corning Gorilla Glass.

Operating System: AndroidOS Version: 5.0.2, LollipopHandling the software affairs on the Obi WorldPhone SF1 is the brand’s custom skin on top of Android 5.1 Lollipop. Dubbed as LifeSpeed UI, the layer offers custom icons along with a few preloaded apps. The lock screen features an interesting circular dial up front that lets you unlock the phone or access the dialer or camera app directly. Once unlocked, you are greeted by the homescreen, which has a vertical strip of eight apps. There are two homescreens by default, and if you dislike the recent shift towards unified homescreens (on most skins from Chinese brands), then you’ll appreciate the fact that this Obi phone has a dedicated app drawer. What’s extremely odd though is the fact that the homescreen doesn’t have the dialer app by default, though of course, you can drag it from the app drawer.  Talking about the preloaded content, you’ll find an anti virus, popular utility app Clean Master and Microsoft’s Office suite covering Word, PowerPoint and Excel.  There’s also an app from Obi, which helps you to locate nearby service centres, although strangely, it only shows the ones present in Vietnam and there’s no option to change the country.In terms of features, you can customise the usage of power and volume buttons, as well as the home key. You can also pick up the call automatically as soon as you bring the phone near your ears or flip the phone to mute the call. With the proximity sensor, you can capture a screenshot or an image by moving your hand over it.One good thing that Obi offers with the WorldPhone SF1 is the option to switch to stock Android interface. We certainly like this capability, as the customisations by the brand look half-baked and seem to ruin the experience, rather than improving it. We also ran into a couple of crashes which most probably were due to the unoptimised software.

Primary camera: 13 MPFlash: LED FlashSecondary camera: 5 MPOn paper, the Obi WorldPhone SF1 has a powerful camera, with a 13-meg sensor from Sony with f/2.0 aperture taking care of primary photos and an 5MP camera at the front for selfies. What’s more, you can use both the shooters in dim settings as both of them get help from dedicated LED flash units. The camera app’s interface is heavily modified, letting you capture images, videos or preview them with the options towards the right in the landscape mode. The app offers a variety of modes such as IQ Camera, Portrait, Night, Snow, etc. as well as various effects like Sepia, Posterize, and Sketch, among others. You can also switch to the front camera or toggle flash, while the last option on the left brings the settings menu. It lets you change ISO levels, exposure, enable HDR, etc. Sadly, the images don’t deliver on the expectations. Most images turn out over-exposed, and while details are fine, colours reproduction doesn’t look realistic. It’s still fine for daylight photography, but capturing images in poor light results in artificial-looking images. The phone does get some help from software features under the option called IQ Camera, such as Opti zoom, Chrome Flash and ReFocus. Opti zoom helps in capturing long shots as you can zoom in without much pixelation, as the camera captures multiple shots and then combines together. Chrome flash results in better images in low light, as it merges two images – one with flash and one without, offering more natural colours. ReFocus, as the name suggests, lets you change the focus on the subjects after capturing the scene.Take a look at the images captured by the rear snapper on the Obi WorldPhone SF1.  Talking about video capabilities, the rear camera can capture videos in 1080p, while the front shooter is capable of recording in HD resolution.
