We also saw most of the features that the Lenovo Vibe S1 is offering, but we missed one interesting thing. According to @upleaks, the Vibe S1 has a dual front-facing camera.
Assuming the handset will be released in the near future, it could become the world's first smartphone with a dual selfie camera (which, similar to the dual rear cameras that HTC is using, should allow you to take photos with bokeh effects).
As you can see below, the Vibe S1 does indeed seem to have two cameras on the front, in the upper right corner. At least one of them should include an 8 MP sensor.
Apart from the unique front-facing camera, the Lenovo Vibe S1 features a 13 MP rear camera with LED flash, a 5-inch 1080p display, 2 GB of RAM, and 16 GB of expandable internal memory. The handset is powered by an octa-core Snapdragon 615 processor, and should run Android Lollipop out of the box.
Right now, we don't know exactly when the Lenovo Vibe S1 will be launched, and neither for what price. Would you be interested in getting one?
