After the Oppo N3 cameraphone, the company unveiled its first 64-bit smartphone, which is coincidentally also its thinnest yet. The Oppo R5 measures just 4.85mm thick, the "slimmest phone in the world," Oppo claims. The company has shaved quite a bit of thickness compared to the 6.3mm Oppo R3.

The frame of the phone is made of 3D-welded aluminum alloy. The frame has been hand-polished and measures just 4mm thick. The other measurements are 148.9 x 74.5mm (that's rather tall for a 5.2" device) and the weight is 155g.

Anyway, the Oppo R5 has a 5.2" AMOLED screen of 1080p resolution (423ppi). The company is promising the best brightness, lowest reflectivity and highly accurate colors.

The R5 will launch with Android 4.4-based Color OS 2.0. It's powered by Snapdragon 615, Qualcomm's mid-range octa-core chipset. It features an octa-core Cortex-A53 processor at 1.5GHz, which is paired with an Adreno 405 GPU and 2GB RAM.

Oppo has created a special cooling element made from liquid-metal and phase-change materials to take heat away from the chipset.

The back camera features the 13MP Sony IMX214 sensor and an f/2.0 aperture, while the front camera is a 5MP shooter. As you can see though, the back camera sticks out quite a bit. Anyway, it can record 2160p video at 30fps and 1080p@60fps, plus a 120fps slow-motion mode (at 720p).

Despite being so thin, the Oppo R5 packs a 2,000mAh Li-Polymer battery, which will be quick to top up thanks to the VOOC mini rapid charge tech support. Connectivity starts off at 2G GPRS and goes up to TDD/FDD LTE. There's also Wi-Fi a/b/g/n, Bluetooth 4.0.

There's one thing missing - a 3.5mm audio jack. We suppose it's because the R5 is so thin, but you either have to use the wireless O-Music accessory for streaming or a microUSB to audio jack adapter (one is included in the retail package).

The Oppo R5 will go on sale for $499 though we don't have an exact launch date yet. But you are welcomed to check our first impressions of the Oppo R5 right here.
