Vivo rumoured to launch slimmest phone ever
Vivo rumoured to launch thinnest smartphone everWeibo

Oppo released R5, touted as the thinnest smartphone in the world, a few days ago. With a thickness of just 4.85mm, it beat Gionee Elife S5.1 by 0.16mm. But Oppo might not be able to keep its size zero record for long, as sources say fellow Chinese smartphone maker Vivo will soon launch a smartphone with just 3.8mm thickness.

Vivo has already released a few photographs of this purported smartphone through Weibo, a popular Chinese networking website. In the images, Vivo has compared the phone's thickness with the previous Apple flagship device iPhone 5S.

Before Oppo R5's release, Ginoee Elife S5.1 had held the Guiness Book of World Records title for the slimmest smartphone in the world. Elife S5.1 is a midrange device, with a 4.8-inch super AMOLED display, 720x1,280 resolution and 320 ppi. The phone is powered by a quad-core (Qualcomm Snapdragon 400) Cortex-A7 processor and is backed by 1GB RAM. The handset also sports 5MP and 8MP cameras with 2300 mAH battery.

But with R5, Oppo snatched the slimmest phone title from Gionee Elife S5.1. The R5 measures 148.9x74.5x4.85mm, with a weight of 155g. It comes with a 5.2-inch full HD screen at 423 ppi. It also integrates Snapdragon 615 SoC, 2GB Ram, 13MP camera and 2000 mAh battery. To keep thickness as its USP, Oppo has sacrificed the essential 3.5mm audio port on the device.

Meanwhile, Vivo is yet to release the world's slimmest smartphone. Other than the pictures, Vivo has not posted any technical specifications of the phone. It will miss the essential 3.5mm audio port, like R5, for sure. Also, the device might not feature a high capacity battery as most of the high capacity Li-ion based batteries come thick.

Besides, there will be concerns on the device's durability, following Apple's notorious #BendGate conundrum. Vivo might employ a different material for construction like Oppo, who used lithium-aluminium material for adding durability without compromising the form factor.
