Mobile phone vendors, to stimulate demand among consumers buying another phone or replacing their old one, began lowering prices. Now, with demand sated, vendors have brainstormed new tactics. Display screens are shifting from black-and-white to color, single screens have become dual screens, and the ability to take photographs has been added, successfully sparking a new sales boom.
