Nokia Lumia 830 available in the states from Expansys USA
The Nokia Lumia 830 is equipped with a 5 inch screen offering a resolution of 720 x 1280. That combination provides a pixel density of 294ppi. Driving the phone is a quad-core 1.2GHz Snapdragon 400 CPU with an Adreno 305 GPU handling graphics. 1GB of RAM is on board along with 16GB of native storage. A 128GB capacity microSD slot is available and a 10MP rear-facing camera has an aperture of f/2.2, which should allow the camera to snap decent shots in low-light conditions. And with OIS, your trembling hands don't make watching your videos a painful experience. A .9MP camera is found on the front of the phone, which is powered by a 2200mAh battery. Windows Phone 8.1 is pre-installed, which means that personal assistant Cortana comes with the model.
Eventually, the Nokia Lumia 830 will be available from AT&T for a subsidized price. But that could be more than a month away. If you don't mind paying the retail price for the phone, you can purchase it right now from Expansys USA.
