The user interface is refined in many ways across the system, making it easier to learn, faster to use, and more power-efficient.

The soft keyboard is redesigned and optimised for better typing experience. The keys are realigned and repositioned to sight them better and to press them accurately even at high speeds. The keyboard also displays the current character and word suggestions from the dictionary in a large, more vivid style that is easier to read.

The keyboard adds the capability to correct entered words from suggestions in the dictionary. The user can also switch to voice input mode to replace the selection.

When entering text or viewing a web page, the user can quickly select a word by press-hold, then copy to the clipboard and paste. Pressing on a word enters a free-selection mode — the user can adjust the selection area as needed by dragging a set of bounding arrows to new positions, then copy the bounded area by pressing anywhere in the selection area. For text entry, the user can slide-press to enter a cursor mode, then reposition the cursor easily and accurately by dragging the cursor arrow. With both the selection and cursor modes, no use of a trackball is needed.

The Android system takes a more active role in managing apps that are keeping the device awake for too long or that are consuming CPU while running in the background. By managing such apps — closing them if appropriate — the system helps ensure best possible performance and maximum battery life.

The system also gives the user more visibility over the power being consumed by system components and running apps. The Application settings provides an accurate overview of how the battery is being used, with details of the usage and relative power consumed by each component or application.

The user can make voice calls over the internet to other users who have SIP accounts.
An NFC Reader application lets the user read and interact with near-field communication (NFC) tags.

The Downloads application gives the user easy access to any file downloaded from the browser, email, or another application. Downloads is built on an completely new download manager facility in the system that any other applications can use, to more easily manage and store their downloads.

Now the camera application lets the device access multiple cameras. Like the front facing camera if required.
