According to Bloomberg, Amazon is developing a smartphone to go head-to-head with the iOS and Android handsets. Amazon is reportedly working with Foxconn to build the device, the same manufacture for many of Apple’s mobile devices including the iPhone and iPad.

In order to prepare for the launch of their phone, Amazon plans to build up a wireless-related patent portfolio, according to the report. Amazon already sells the successful Kindle Fire with a 7-inch display, a device that demonstrates the firm’s aptitude for building a high-quality, customized mobile operating system (based on Android).
