1. The HTC One A9 has a 13-megapixel camera, and is the first non-Nexus phone to use Google’s newest operating system. In fact, the HTC One A9 is a combination of sleek design packed with the latest Android Marshmallow software. The phone is the first outside of Google’s own Nexus line to feature that company’s Marshmallow OS at launch. The A9 will go on sale globally next month (early November), but is available for pre-order - US preorders for silver and gray phones are now being taken through HTC’s website for $400.
