Why Future Android Devices Will Have Less Bloatware

If a phone manufacturer wants its users to have access to the Google Play app store, then Google requires the company to include a large bundle of its apps on the device preinstalled in an all-or-nothing type of scenario. Some of the apps that Google requires manufacturers to preinstall on its devices to access the Google Play app store include Gmail, Google Maps, Google Chrome and YouTube. Some of the apps that used to be required includes Google+, Google Keep, Google Earth, Google Play Games, Google Play Books and Google Newsstand.
Even though Android is being freed up from a large amount of bloatware, phone carriers may still add their own preinstalled apps to the devices. For example, AT&T Navigator, Sprint Zone and Verizon Messages could still be added to the devices.
