One of the two new members of the Vibe family from Lenovo, the S1 is a 5-inch Android phone with a focus on the front-facing cameras.
On the rear of the Vibe S1 is a standard 13-megapixel camera with a dual-tone flash for a more natural colour spectrum. You can also see the curved glass styling of the S1.
But on the front Lenovo has packed in not one, but two front facing cameras. One is an 8-megapixel while a second 2-megapixel camera adds more depth and dimension to self-portraits, according to Lenovo.
Inside the S1 there's a 64-bit, 1.7GHz octa-core processor from MediaTek. It's running on Android 5.0 you'll get 32GB of internal storage, with room for up to 128GB via MicroSD.
The Vibe S1 is also a dual-SIM device and has a 2,500mAh battery. It's not removable though -- Lenovo joins many other manufacturers in sealing up their unibody designs.
Like a lot of other selfie cameras, the S1 can be triggered remotely and there's even a physical remote, sold separately of course.
At 5-inches the screen comes in around the average size for most modern phones. It's full high-definition with a 1,920x1,080-pixel resolution.
Lenovo starts selling the Vibe S1 globally in November although the pricing and full list of regions hasn't been finalised. Expect to see it for around $300 though.
Just in case you were doubting Lenovo's commitment to the selfie, the S1 comes with a plug in ring flash for that professional look.
