Oppo are on a roll today. Their new flagship, the N3, has just been formalized and now we’ve got this, the Oppo R5. It’s made using “reinforced industrial grade aluminum alloy” and it’s also hand-crafted in ceramic too. However, the big selling point here is the thickness – or should I say “slimness”. It’s just 4.85mm and Oppo have claimed it to be the slimmest smartphone in the world. Currently, the slimmest smartphone is the KAZAM Tornado 348, at 5.15mm. The R5 beats that by quite a margin.
