Over-the-air (OTA) updates let you deliver changes directly to your users, super fast and without any fuss. In this talk, we’ll explore various OTA update techniques, from simple tools to advanced methods like code push for instant fixes, feature flags for controlled rollouts and A/B testing, server-driven UI for dynamic content, and even generative AI for personalized experiences.
