Android 4 provides a range of new features such as improved network data settings, user profiles and more.
Network Data Settings
To meet the needs of users with tiered or metered data plans, Android 4 adds new controls for managing network data usage. In the Settings app, colorful charts show the total data usage on each network type (mobile or Wi-Fi), as well as amount of data used by each running application. Based on their data plans, users can optionally set warning levels or hard limits on data usage or disable mobile data altogether. Users can also manage the background data used by individual applications as needed.
People and Profiles
Throughout Android 4, a user's social groups, profiles, and contacts are linked together and integrated for easy accessibility. At the center is a new People app that offers richer profile information, including a large profile picture, phone numbers, addresses and accounts, status updates, and a new button for connecting on integrated social networks.
The user's own contact information is stored in a new "Me" profile, allowing easier sharing with apps and people. All of the user's integrated contacts are displayed in an easy to manage list, including controls over which contacts are shown from any integrated account or social network. Wherever the user navigates across the system, tapping a profile photo displays a Quick Contacts, with shortcuts to phone numbers, email and text messaging, and more.
Unified Calendar and Visual Voicemail
To help organize appointments and events, an updated Calendar app brings together personal, work, school and social agendas. With user permission, other applications can contribute events to the calendar and manage reminders, for an integrated view across multiple calendar providers. The app is redesigned to let users manage events more easily. Calendars are color-coded and users can swipe left or right to change dates and pinch to zoom in our out agendas.
In the phone app, a new visual voicemail feature integrates incoming messages, voice transcriptions, and audio files from one or more providers. Third-party applications can integrate with the Phone app to add their own voice messages, transcriptions, and more to the visual voicemail inbox.
