Abstract: Aspects of subject technology provide systems and methods for generation and distribution of a stable identifier associated with multiple aliases of a user account. The stable identifier may be provided to various electronic devices by a server, responsive to requests associated with communications to those devices from one of the associated aliases. In this way, messaging applications can utilize the stable identifier to merge conversations from a single user having multiple aliases, and secure access to a secure device can be provided to an authorized user, even if the authorized user attempts access from an unauthorized account alias.

Abstract: A device implementing a system for packet loss management may include a memory and at least one processor configured to identify a plurality of categories of packets provided for transmission to an electronic device.

Abstract: Implementations of the subject technology provide for storing a temporary certificate on a mobile device for accessing services in association with a primary number. A device determines that a first subscriber identity module (SIM) card, previously used by the device, is not available for use by the device. The device determines that a second SIM card is available for use by the first device within a predetermined time period after the first SIM card is determined to be not available for use by the device. The device confirms that a communication identifier of the first SIM card is strongly tied to a user account associated with the device. The device stores a temporary certificate that attests to continued ownership of the communication identifier by the device and allows the device to access at least one service in association with the communication identifier.

Abstract: A messaging system, in one embodiment, can establish messaging accounts for a plurality of organizations (e.g., businesses) to allow customers or users of the organizations to conduct two-way messaging sessions between a customer and an organization. The messaging system can use a registration portal to allow an organization to set up a business/organization messaging account by providing account information. The account information can then be used to update one or more searchable databases that allow a customer to have multiple entry points into a messaging session with each of the registered businesses in the messaging system. For example, a search through a web browser or a map application can provide search results that contain or otherwise provide access to a selectable messaging option that is presented on a customer's device.

Abstract: Participant systems in an audiovisual (AV) conferencing can, in one embodiment, use methods to ensure that all participants have a common platform to support AV conferencing, such as a common codec, and also attempt to provide higher quality AV conferencing (e.g., better than the common codec) based on available bandwidth and other criteria. The participant systems can use the common codec as a fallback platform when bandwidth or other criteria dictate a reduction in the quality of the AV conferencing. Other embodiments are also disclosed.

Abstract: Aspects of the subject technology provide for shared experience sessions within a group communications session such as a video call. The shared experience session may be, as one example, a co-watching session in which the participants in the call watch a video together while in the call. Encrypted shared state data may be exchanged between the participant devices, with which the participant devices can provide synchronized and coordinated output of shared experience data for the shared experience session of the group communications session.

Abstract: A quick relay communication protocol is used by an initiating communication device (such as a wearable electronic device, e.g., a smart watch) and/or a recipient communication device (such as a companion electronic device to the wearable electronic device, e.g., a smart phone, a tablet computer or a laptop computer) to selectively communicate messages via different communication channels. Based on available connections and a communication constraint associated with a message, a processor executing a program module in an application layer in the initiating communication device provides transmission instructions to an interface circuit in the initiating communication device, which transmits a message to the recipient communication device based on the transmission instructions.

Abstract: Systems, methods and non-transitory computer readable media for allowing a user to switch between wearable items that have been paired or associated with an electronic device, such as a smartphone, are described. In one embodiment, the wearable items automatically detect a removal of a first wearable item from a user's body and an attachment of a second wearable item to the user's body. Messages from the wearable items are transmitted to the electronic device to allow the electronic device to switch the active wearable item from the first wearable item to the second wearable item. The switch can occur while the electronic device is in a locked state, and the electronic device can synchronize the second wearable item with data received from the first wearable item. Other embodiments are also described.

Abstract: Messaging between a companion device and an accessory device is controlled such that different modes of communication may be utilized. The different modes can implement different messaging strategies, each of which is intended for efficient power management, in view of the limited electrical power that is typically available at the accessory device. A received request message for sending from the companion device to the accessory device is sent if predetermined conditions apply, and similarly for messages from the accessory device to the companion device.
