Microsoft today announced a handful of features of the next version of Windows Phone. The slate of changes announced center on supporting cheaper hardware and developing markets. The new software will support Qualcomm's newer low-end Snapdragon 200 and 400 chipsets. It will also reduce memory requirements and allow apps loaded on removable memory cards. Microsoft will also remove the requirement for three hardware buttons below the screen and a dedicated camera button. This is designed to allow manufacturers to re-use hardware designed for Android phones. Microsoft will also expand its driver support for common hardware parts used in Android phones, further making it easier for manufacturers to offer a phone in both Android and Windows Phone versions. Microsoft will also support dual-SIM phones in the new version. The company is expected to fully reveal the new Windows Phone OS at its upcoming Build conference.
