Lenovo, which bought Motorola Mobility from Google in 2014, is unifying its two phone businesses under the Lenovo name. It's going to use Motorola's Moto brand for high-end products and its homegrown Vibe brand for budget devices. The Motorola name isn't completely gone. It will live on from a corporate perspective as a division of the Chinese consumer-electronics giant, said Motorola Chief Operating Officer Rick Osterloh.
