Huawei didn't go nearly as far as ZTE in releasing a bunch of Android phones, but the company did actually expand its 2012 lineup more than it let on while unveiling the Ascend D quad. The "Diamond" line includes the aforementioned quad, the D quad XL with a larger battery, and the Ascend D1. The D1 is identical in every way to the quad with one important exception: it uses an unnamed dual-core 1.5GHz processor instead of Huawei's K3 processor. Actually, the D1 also has a very slightly different pattern on its soft-touch back that looks almost identical to the original Atrix 4G's styling.
In a twist we can't entirely explain, Huawei has loaded up the D1 with both stock Android and a custom skin with 3D effects — but remarkably the company made switching between the two homescreen and launcher experiences a simple menu option away. We don't know if this is an effect of alpha software, but we do know that a manufacturer offering such a simple opt-out on its skin is a wonderful idea.
During its press conference, Huawei said that the Ascend D quad would come in an LTE version later, but in the meantime it's doing the exact same thing that other phone manufacturers have been doing here at MWC. The non-LTE Ascend D lte gets the quad-core chip (be it K3 or Tegra 3), while the LTE device utilizes Qualcomm's dual-core MSM8960. The chip is clocked at 1.5GHz, but otherwise the phone is also identical to the quad — assuming of course that actual shipping units don't have the build quality issues of the prototypes on the floor.
Finally, Huawei has a lower-end Ascend P line of phones and it's adding an LTE option there as well. The Ascend P1 lte uses that same 1.5GHz dual-core Qualcomm processor, but has only a 4.3-inch qHD display. Other specs include 1GB of RAM, 4GB of storage, Bluetooth 3.0, and a 2000mAh battery.
