Android Lollipop, Marshmallow and Nougat

This is a list of features in the

Android operating system.[1][2][3]

General

Messaging
SMS and MMS are available forms of messaging, including threaded text messaging and Android Cloud To Device Messaging (C2DM) and now enhanced version of C2DM, Android Google Cloud Messaging (GCM) is also a part of Android Push Messaging services.
Auto Correction and Dictionary
Android Operating System has an interesting feature called Auto Correction. When any word is misspelled, then Android recommends the meaningful and correct words matching the words that are available in Dictionary. Users can add, edit and remove words from Dictionary as per their wish[4].
Web browser
The web browser available in Android is based on the open-source
AOSP browser', 'stock browser', 'native browser', and 'default browser'. Starting with Android 4.4 KitKat, Google has mandated that the default browser for Android proper be Google Chrome.[citation needed
] Since Android 5.0 Lollipop, the WebView browser that apps can use to display web content without leaving the app has been separated from the rest of the Android firmware in order to facilitate separate security updates by Google.
Voice-based features
Google search through voice has been available since initial release.[5] Voice actions for calling, texting, navigation, etc. are supported on Android 2.2 onwards.[6] As of Android 4.1, Google has expanded Voice Actions with ability to talk back and read answers from Google's Knowledge Graph when queried with specific commands.[7] The ability to control hardware has not yet been implemented.
Multi-touch
Android has native support for multi-touch which was initially made available in handsets such as the HTC Hero. The feature was originally disabled at the kernel level (possibly to avoid infringing Apple's patents on touch-screen technology at the time).[8] Google has since released an update for the Nexus One and the Motorola Droid which enables multi-touch natively.[9]
Multitasking
Multitasking of applications, with unique handling of memory allocation, is available.[10]
Screen capture
Android supports capturing a screenshot by pressing the power and home-screen buttons at the same time.[11] Prior to Android 4.0, the only methods of capturing a screenshot were through manufacturer and third-party customizations (apps), or otherwise by using a PC connection (DDMS developer's tool). These alternative methods are still available with the latest Android.
TV recording
Android TV supports capturing video and replaying it. [12]
Video calling
Android does not support native video calling, but some handsets have a customized version of the operating system that supports it, either via the UMTS network (like the Samsung Galaxy S) or over IP. Video calling through Google Talk is available in Android 2.3.4 (Gingerbread) and later. Gingerbread allows Nexus S to place Internet calls with a SIP account. This allows for enhanced VoIP dialing to other SIP accounts and even phone numbers. Skype 2.1 offers video calling in Android 2.3, including front camera support. Users with the Google+ Android app can perform video chat with other Google+ users through Hangouts.
Multiple language support
Android supports multiple languages.[13]
Accessibility
Built-in text-to-speech is provided by TalkBack for people with low or no vision. Enhancements for people with hearing difficulties are available, as are other aids.

Connectivity

Connectivity
Android supports connectivity technologies including
IDEN and WiMAX
.
Bluetooth
Supports voice dialing and sending contacts between phones, playing music, sending files (
HID) support is available in Android 3.1+, and in earlier versions through manufacturer customizations and third-party applications.[14]
Tethering
Android supports tethering, which allows a phone to be used as a wireless/wired Wi-Fi hotspot. Before Android 2.2 this was supported by third-party applications or manufacturer customizations.[15]

Media

Streaming media support
RTP/RTSP streaming (
RealPlayer for Android,[17] and by the operating system since Android 3.0 (Honeycomb).[18]
Media support
Android supports the following audio/video/still media formats:
GIF, BMP, and WebP.[3]
External storage
Most Android devices include microSD card slots and can read microSD cards formatted with the
HFS Plus and exFAT
.

Hardware support

Android devices can include still/video cameras,

pressure sensors, thermometers, accelerated 2D bit blits
(with hardware orientation, scaling, pixel format conversion) and accelerated 3D graphics.

Other

Java support
While most Android applications are written in
J2ME
support can be provided via third-party applications.
Handset layouts
The platform works for various screen sizes from smartphone sizes and to tablet size, and can potentially connect to an external screen, e.g. through HDMI, or wirelessly with Miracast. Portrait and landscape orientations are supported and usually switching between by turning. A 2D graphics library, 3D graphics library based on OpenGL ES 2.0 specifications is used.
Storage
SQLite, a lightweight relational database, is used for data storage purposes.
Native Apps
Android apps are also written in HTML.
Instant Apps
Android apps are hosted on a specific website path and load instead of the website itself. They are part-apps and load almost instantly without the need for an installation. One of the first apps being developed with such functionality is the B&H app.[19][20][21]
