Abstract: Aspects of the present disclosure involve a system comprising a computer-readable storage medium storing at least one program, method, and user interfaces to facilitate electronic chat conversations between users via multiple modes of electronic communication. A conversation view is displayed on a touch screen display of a client device. The conversation view presents messages exchanged between a first user and at least one other user in an electronic chat conversation. A user input comprising a touch gesture corresponding to an interaction with the display of the conversation view is received. Based on the user input, a camera feed view is displayed on the touch screen display. The camera feed view comprises a display of image data and enables a user to create a message comprising one or more images. A message is generated, and an indication of the message is displayed in the conversation view.

Abstract: A method and a system include receiving indication of a user interaction within a pre-determined time period, determining that the user interaction is a contextual triggering event based on a plurality of triggering conditions, identifying a media content item associated with the contextual triggering event, generating a first user interface including a user-selectable element representing a content transmission proposal, in response to detecting a user selection of the user-selectable element, generating a second user interface, the second user interface including the media content item and a plurality of user-selectable entity icons.

Abstract: Systems, devices, methods, and instructions are described for generating and using expressive icons with status indicators for a map based graphical user interface (GUI). One embodiment involves accessing location information, map data icon information, and action indicator information associated with an account of a social media platform. A device then causes generation of a combined action icon generated using the icon information and the action indicator and causes display of a map interface with the map data and the combined action icon positioned at a location indicated by the location information.

Abstract: Systems and methods are provided for performing operations including: retrieving, by one or more processors, a plurality of content items; identifying a first content item from the plurality of content items to which a user has previously reacted; determining a category of the first content item; selecting a second content item in the plurality of content items that is associated with the determined category of the first content item to which the user has previously reacted; and presenting the second content item to the user in a presentation arrangement of a graphical user interface.

Abstract: Systems and methods to generate and cause display of a contextual navigation menu within a GUI, wherein the contextual navigation menu presents contextually relevant interface elements.

Abstract: The technical problem of automatically reprocessing an image captured by a camera in a manner that produces a personalized result is addressed by providing a customized image reprocessing system powered by machine learning techniques. The customized image reprocessing system is configured to automatically reprocess an image on a pixel level using a machine learning model that takes, as input, the image represented by pixel values, sensor data detected by the digital sensor of a camera at the time the image was captured, and, also, flash calibration parameters previously generated for that specific user.

Abstract: A messaging system comprises: one or more processors; and one or more computer-readable mediums storing instructions that, when executed by the one or more computer processors, cause the messaging system to perform operations. The operations comprise: receiving a message; displaying an in-application notification of the received message; displaying the received message upon receiving a user command in response to the displayed notification; the user command comprising touching the notification on a screen; wherein the displaying the received message displays the message in an upward motion from a bottom of the screen.

Abstract: A method and a system include receiving indication of a user interaction within a pre-determined time period, determining that the user interaction is a contextual triggering event based on a plurality of triggering conditions, identifying a media content item associated with the contextual triggering event, generating a first user interface including a user-selectable element representing a content transmission proposal, in response to detecting a user selection of the user-selectable element, generating a second user interface, the second user interface including the media content item and a plurality of user-selectable entity icons.

Abstract: The technical problem of enhancing the quality of an image captured in low light conditions by a front facing camera is addressed by providing an adaptive front flash system. An adaptive front flash system automatically adjusts configuration parameters of an overlaid view that operates in lieu of a front flash, termed a front flash view. The configuration parameters are adjusted based on characteristics of the output of the digital image sensor of the front facing camera. Examples of configuration parameters of the front flash view include one or more of brightness of the display, color temperature of the front flash view, and transparency of the front flash view.

Abstract: A social network image pool system can capture one or more image data items (e.g., image, video) in a temporary persistent post pool. The post pool enables for efficient capture of multiple image data items for publishing in a manner that allows multiple images data items to be captured while preserving the editability of the multiple items before they are published to a social network site.
