The newest edition to Lenovo's Vibe lineup of phones, the Vibe C, is the latest ultra low-cost smartphone with enough power to be a decent backup device for some users (or at least a great burner). The Lenovo Vibe C comes with a 5-inch 720p display, a quad-core processor, 4G LTE connectivity, 1GB of RAM, 5MP camera, Android 5.1.1. Lollipop, and 8GB of storage, which can be expanded to 32GB via the microSD slot.
Those aren't great specs by most standards, but for $105, the Vibe C could be a nice pickup for someone looking for a second phone. Currently the Vibe C is only being sold in Croatia, but Lenovo is likely to broaden availability in the coming weeks. The Vibe C will begin shipping on May 18th.
