FOTA updates on Android are a crucial aspect of keeping devices secure and up-to-date. The process involves downloading and installing OS updates Over-the-Air (OTA), without requiring a physical connection to a computer, which has become increasingly robust since the first public release of Android. FOTA updates can be used for security patches, feature updates, and Android version upgrades. There are two kinds of OTA implementations on Android: A/B (Seamless) Updates and traditional (non-A/B or A-only) Updates. A/B updates are considered better due to their quick and seamless process with minimal downtime, while traditional updates have advantages such as reduced space usage but also disadvantages like non-seamless updates and potential manual rollbacks. Most OEMs provide FOTA services for consumer Android devices, but this can be a challenge in enterprise scenarios. Esper platform offers a user-friendly cloud interface to deploy FOTA updates to any and all EEA devices on the schedule, abstracting away technical jargon and simplifying the process.
