On one hand, the Huawei Summit comes loaded with features you'd expect from a smartphone, such as the 3.5-inch HVGA touchscreen, 3G and Wi-Fi connectivity with support for Wi-Fi calling. There is also a GPS radio with navigation capabilities, a 3.2-megapixel camera that can capture video as well, and a 3.5-millimeter headphone jack that allows the handset to be used as a media player. Even Swype comes loaded on the device, and the interface has that pronounced Android feel.
However, the specs page for the Huawei Summit mentions that it runs on a "proprietary operating system", which we aren't sure how to interpret. It is possible that the handset is an Android smartphone indeed, yet what's installed on it is a modified version of the platform that has been stripped down of the Google apps, such as Gmail, the Play Store, and the likes. We'll look into the matter and let you know as soon as we find out what the case is.
