Huawei is making quite a splash at this year’s Mobile World Congress. The company announced one quad-core handset — the Ascend D quad, which is built on the company’s proprietary in-house processor platform — in addition to a dual-core TI OMAP-based device, the Ascend D1. We got a chance to play with both models and, especially in the case of the D quad, we left quite impressed. These things move fast. Really fast. What’s more, these handsets mark Huawei’s entry into the chip making game, and place the company in direct competition with other smartphone vendors that moonlight as chip makers, like Samsung and Apple. It will be interesting to see how this plays out over the coming year. That said, the handsets themselves will be the stars of Huawei’s lineup for at least the first half of 2012. The D quad sports 8GB of on-board storage, 1 GB of RAM, Android 4.0, Huawei’s 1.2Ghz quad-core chip, a 4.5-inch display and Android 4.0 Ice Cream Sandwich. The Ascend D1 is externally identical to the D quad, but it will hit a much lower price point thanks largely to its 1.2Ghz dual-core chip, which replaces the D quad’s quad-core processor.
