Even the Oppo Finder has a 6.65mm thickness and yet lacks a 3.5mm headphone jack, whereas BBK's thinner phone has one.

Measuring at 6.93mm thick (instead of the rumored 6.13mm), we're surprised that Oppo didn't set this to be the follow-up to the Finder: sure, it's 0.28mm thicker, but it also aces the latter with a 4.7-inch 720p in-cell display, a 1.2GHz quad-core chip with 1GB RAM (likely MediaTek's Cortex-A7-based MT6589 SoC), Android 4.2 and a sorely missed 3.5mm headphone jack -- so no micro-USB adapter required.
