It's no secret that Amazon's Fire Phone tanked on the market. But while the e-commerce giant is keeping a distance from smartphone manufacturing business for some time, it is not ignoring the platform. The company is now willing to offer its Prime members a $50 discount on two unlocked phone models should they agree to see ads on the lock-screen of their smartphone. Recode reports:Unlike the Fire Phone, which used Amazon services in place of Google, these two phones (the fourth-generation Moto G and Blu R1 HD) will include all the standard Google apps (Play Store, YouTube, Gmail, Chrome, etc.) along with Amazon apps for shopping, watching video and playing music. With the discount, the Blu phone will sell for just $49, while the price of the Moto G drops to $149. The move is clearly a modest one but could at some point become more significant, particularly if Amazon is willing to strike deals with other hardware makers to include its apps and services.The bigger news is Amazon finding its way into Google Mobile Services-powered Android smartphones. Most of the Amazon-branded devices don't have Google Mobile Services (Google Play, Google Play Services, Gmail etc).
