The OBI SF1 comes packaged in a transparent acrylic box and is strikingly similar and can be termed as a nice fusion of iPod Touch and Microsoft Lumia device. The SF1 is built well, has a striking design, and is comfortably sized. The 5-inch full-HD IPS display is beautifully crisp; colours are punchy and sunlight legibility is fairly good too. The Obi measures at 146*74*8 mm, with a “floating display” raised at 0.2 mm that encases a 5-inch IPS display letting it easily slide into and out your pocket. The rest of the body is made of plastic except for a strip of flat metal on the top, where we have the 3.5mm headset socket. The hybrid SIM slot is placed on the right, while the volume and power buttons are on the left. The speaker grille and Micro-USB port are on the rounded bottom. The Lumia-style body features a matte finish, which helps with grip and is easy to keep clean. Around the back, the OBI SF1 has a 13-megapixel camera and LED flash. The 13-megapixel camera manages very good macros in daylight.
Apart from the usual suite of Google apps and some productivity apps, there's also Obi Care, which lists available service locations; Microsoft Word, Excel and Powerpoint; SwiftKey keyboard; and Dolby Audio.
