Huawei has been relatively quiet of late. Aside from Ascend D Quad smartphone we saw announced back at MWC, the company hasn’t been very present on U.S. shores. But with LTE hitting its stride, the company has today announced its very first 4G LTE handset: the Activa 4G. MetroPCS will carry the prepaid device, which is a Android 2.3 Gingerbread-powered handset. It sports a 3.5-inch HVGA capacitive touchscreen with a 5-megapixel rear camera (LED flash-enabled) and a VGA front-facing camera for video chat.
