Nokia Lumia 900 Cell Phone Review

The Hardware

The Nokia Lumia 900 uses a single-core, 1.4 GHz Snapdragon S2 APQ8055 processor from Qualcomm, a.k.a. “Scorpion,” which is almost the same chip found in the Lumia 710 and Lumia 800 models. The Windows Phone 7.5 operating system, and all the applications we tried, ran smoothly, with no lags or sluggishness. A single-core processor is used simply because Windows Phone 7.5 doesn’t support multi-core processors.

The Adreno 205 GPU, integrated with the main chip, proved to be effective and fast, even on the 3D games we installed.

As we previously mentioned, the 4.3-inch screen has a resolution of 800 x 480 pixels. This resolution is actually mandatory for any device running Windows Phone 7.5.

Figure 5 shows the back side of the phone. There is no micro-SD slot for a memory card, which is actually a Windows Phone limitation. Here, you can also see the 8 Mpixel camera, Carl Zeiss Tessar lenses, and the dual LED flash.

Figure 6 unveils the top of the phone, where the earphone connector and mini-USB connector are located. There is also a hidden slot where the SIM chip is located. You must insert the pin that comes with the phone into a small hole located near the USB connector in order to open the slot.

At the right side of the phone, there are four buttons: the camera shutter, lock/power button, and the volume settings. There isn’t any connector or button at the left side of the phone.
