Abstract: Some embodiments of a method for withdrawal a message include receiving, by a mobile device, an input to send a first message to a first recipient, the first message containing at least one image or video. The mobile device processes the first message for transmittal to the first recipient. In response to detecting a request to withdraw the first message within a timeout period, the mobile device determines that the first message has not been sent from the mobile device and terminates the processing of the first message for sending.

Abstract: Systems, methods, and non-transitory computer-readable media can transmit at least a media content item to a recipient device. A response can be received from the recipient device. At least the media content item can be obscured to produce an obscured media content item. The response and the obscured media content item can be presented. The response can overlay the obscured media content item.

Abstract: A social networking system user identifies one or more social networking system users authorized to present content items to the user via the social networking system (“authorized users”). When an additional user requests presentation of a content item to the user, the social networking system determines if the additional user is an authorized user. If the additional user is an authorized user, the content item is presented to the user. However, if the additional user is not an authorized user, the social networking system identifies the additional user to the user along with a request to identify the additional user as an authorized user. If the user identifies the additional user as an authorized user in response to the request, the content item is presented to the user.

Abstract: A user interacts with a messaging application on a client device to capture and send images to contacts or connections of the user, with a single user interaction. The messaging application installed on the client device, presents to the user a user interface. The user interface includes a camera view and a face tray including contact icons. On receiving a single user interaction with a contact icon in the face tray, the messaging application captures an image including the current camera view presented to the user, and sends the captured image to the contact represented by the contact icon. In another example, the messaging application may receive a single user interaction with a contact icon for a threshold period of time, and may capture a video for the threshold period of time, and send the captured video to the contact.

Abstract: A user interacts with a messaging application on a client device to capture and send images to contacts or connections of the user, with a single user interaction. The messaging application installed on the client device, presents to the user a user interface. The user interface includes a camera view, and a face tray. The messaging application automatically populates the face tray with contact icons associated with one or more contacts. The messaging application identifies contacts associated with the user and attributes associated with the contacts. Based on one or more attributes, the messaging application may rank the contacts. Based on the rank associated with the contacts, the messaging application selects one or more contacts to include in the face tray to present to the user or to provide to the user from which the user can select contacts to include in the face tray.

Abstract: When a user requests to send a media message to a contact, a sending device retrieves the device parameter of a receiving device used by the contact to receive messages. Based on the retrieved device parameters, the sending device processes a media file to be included with the media message. The sending device processes the media file to reduce the size of the media file and for the media file not to exceed the display capabilities of the receiving device. The sending device sends the media message with the processed media file to the receiving device of the contact via a messaging system.

Abstract: A social networking system identifies one or more additional users to be presented with a content item to a user presenting the content item (“sending user”). Information maintained by the social networking system and describing prior interaction between the sending user and various additional users is retrieved. Based on the prior interaction between the sending user and the additional users, one or more additional users are identified to the sending user as potential recipients for the content item. For example, a frequency of interaction between the user and additional users, affinity between the user and various additional users, or other suitable information is used to identify potential recipients of the content item.

Abstract: A social networking system user identifies one or more social networking system users authorized to present content items to the user via the social networking system (“authorized users”). When an additional user requests presentation of a content item to the user, the social networking system determines if the additional user is an authorized user. If the additional user is an authorized user, the content item is presented to the user. However, if the additional user is not an authorized user, the social networking system identifies the additional user to the user along with a request to identify the additional user as an authorized user. If the user identifies the additional user as an authorized user in response to the request, the content item is presented to the user.
