May 2026 Summaries

Android Over-the-Air (OTA) updates involve cryptographically signed, partition-aware firmware deployments that execute various verification and rollback procedures to ensure the integrity and security of updates before they are installed on devices. A/B devices, which use dual system partitions, allow updates to be installed on the inactive partition while the device continues to operate normally, minimizing risk and allowing automatic rollback if issues arise. Non-A/B devices, however, go offline during updates and lack automatic rollback, posing a higher risk of rendering devices inoperable without manual intervention. Managing large fleets of devices, especially those with mixed hardware generations, requires advanced orchestration beyond the native Android OTA capabilities, which are limited to per-device self-correction and lack comprehensive reporting and observability at scale. Esper enhances OTA management by providing phased rollout controls, automated rollback policies based on fleet-wide failure rates, and real-time compliance reporting, turning individual recovery events into actionable insights to improve rollout intelligence. This infrastructure is crucial for enterprise deployments to ensure efficient, reliable, and secure updates across diverse device cohorts.

Managing devices at scale programmatically is revolutionized by the adoption of Esper API's capabilities: blueprints, converge, and automated app updates, which together streamline workflows that traditionally consumed hours into those that run automatically. Blueprints serve as versioned configuration objects defining device states, supporting Android, Apple, Windows, and Linux, and ensuring efficient deployment across entire fleets. Converge functions to align devices with their assigned blueprints, using the Commands and Operations APIs to manage configurations and app updates seamlessly across vast numbers of devices. The automation of app updates, from uploading new versions to blueprint modification and execution of converge commands, is simplified into a script, allowing integration into existing CI/CD pipelines. This automation provides an audit trail for changes, enhancing efficiency and scalability for teams managing extensive device fleets, ultimately offering a sustainable solution for enterprise device management.
