(Telecompaper) Huawei Technologies estimated that its smartphone revenue grew about 30 percent this year, exceeding USD 11.8 billion, according to an internal memo seen by Reuters. In a letter to staff, Huawei's consumer-business group head Richard Yu said smartphone shipments reached more than 75 million units in 2014, up 40 percent from a year earlier. That is still short of Huawei's initial target of selling 80 million mobile phones, which would have been an increase of 54 percent from last year.
