Design and Feel

Obi Worldphone SF1 Design & Looks

It is sure that the most striking feature of Obi Worldphone SF1 is its unique and attractive design, which is achieved by the hardwork of the company. The phone, which comes packaged in a transparent acrylic box, looks like a fusion of an iPod Touch and a Microsoft Lumina device. The phone is a made with a blend of metal, glass and poly carbonate. The Obi SF1 features the dimensions of 74.03x 145.92x 7.8 mm and weight of 143 grams is really compact in size and feels brilliant in hands.

While the 3.5 mm headphone jack and a second microphone along with a plastic insert for the antenna bands is placed on the top of the Worldphone SF1, the bottom side occupies two stereo speakers with dual mics for noise cancellation and the mini-USB charging port in between them. The left side possesses only two buttons, the volume control rocker and the power/unlock button. The hybrid SIM card stray slot, which accepts both a second SIM and a microSD card slot, is positioned on the right side.

Display features of phone

Obi Worldphone SF1 Display features

The elevated 5 inch Full HD JDI In-Cell IPS display of Obi Worldphone SF1 has 1920x 1080 pixel resolution and 443 ppi. This beautifully crisp display offers punchy colors and fair sunlight legibility. The clarity, sharpness, the sweet color reproduction and good contrast level of the display makes SF1 the best choice for multimedia consumption. Even though the viewing angles are also good as well, you have to choose the right angle to read clearly, if you are under sunlight. This fully-laminated OGS display avoids fingerprints to a certain level with the help of an oleophobic coating. The display is projected slightly from the rest of the body. This floating display feature gives a different look to the phone, even though it does not offer any functional benefit. At the same time, the chances for absorbing any impact to the display rim are very high, if the phone falls down face-first. But, the Cornia Gorilla Glass 4 for protection prevents the display from this possibility.

The detailing levels of the camera offer clarity of the image, even when you zoom in into the maximum. The focus reticule, which is a little large, makes the app to lock focus on small objects tricky. However, it can provide good detail and depth of field, once locked in. Even though the camera produces clarity pictures in daylight, the images taken in low light are not great. The camera apps come with many features like Refocus, chroma Flash and OptiZoom etc.

Obi SF1 is able to record quality videos up to 1080p with 30 frames per second rate.
