App Hub on Android is a feature that allows Android app developers to upload and distribute their applications via a centralized Google repository. It is a component of the Google Play Console, which is a developer-focused platform that provides various tools and resources to assist developers in developing, testing, and publishing Android applications. App Hub is a cloud-based service that allows app developers to distribute their applications to a large user base efficiently, eliminating the need for developers to host their applications on their servers or distribute them through third-party app stores.

App Hub is not a pre-installed app on Android devices, but rather a tool for developers to distribute their apps. However, some users have reported seeing pop-ups related to App Hub or Carrier Hub on their Android devices. These pop-ups may be related to a service that installs random games and apps on the phone without the users consent.

Here are some key features and advantages of using App Hub on Android:

• Supports multiple app versions, allowing developers to upload different app versions with features and functionality.
• Allows developers to upload beta versions of their apps to get feedback from early adopters before releasing the final version to the public.
• Provides a centralized repository for app distribution, making it easier for users to find and download apps.
• Eliminates the need for developers to host their applications on their servers or distribute them through third-party app stores.

In addition to the Google Play Console, there is also a separate app called Hub App, which is a get-together invitation management tool for casual gatherings and hangouts with friends, family, colleagues, and loved ones.
