The 4.75mm-thin Vivo X5 Max will be announced on December 10

Vivo recently confirmed that it would officially announce its X5 Max smartphone on December 10. This is noteworthy because the handset is only 4.75 mm thin, and will become the world’s slimmest smartphone once it’s officially launched.

At the moment, the world’s thinnest smartphone is the Oppo R5, which measures 148.9 x 74.5 x 4.85 mm. Sure enough, no one will be able to actually notice that the X5 Max is thinner than the Oppo R5 in real life, but that probably doesn't matter too much for Vivo.

Unlike the R5, the X5 Max will include a standard 3.5 mm headset jack, and it looks like Vivo managed to avoid making too many compromises in order to build such a thin handset.

Running Android 4.4 KitKat, the X5 Max will offer a 5.5-inch display with 1080 x 1920 pixels, LTE connectivity, Hi-Fi sound, 13 MP rear camera, 5 MP front-facing camera, 2 GB of RAM, and an octa-core MediaTek processor clocked at 1.7 GHz. We don’t know if Vivo intends to sell the X5 Max outside of China, but we’ll let you know if we hear anything on this.
