Android 15 and 16 have introduced significant changes that impact how dedicated devices are managed, particularly in enterprise settings. For consumers, these updates may appear as minor enhancements, but for IT operators, they present substantial operational challenges due to stricter service rules and security protocols. Android 15, for instance, has altered how foreground services start, imposed stricter controls on PendingIntents, and restructured signature permissions, affecting both AOSP and GMS versions. These changes necessitate that IT teams adapt their management strategies, especially as OEMs like Zebra and Samsung implement new controls and policies. Meanwhile, Android 16 further tightens security and connectivity controls, introducing new features like advanced protection and refined provisioning. The distinctions between AOSP and GMS versions are increasingly pronounced, with Esper Foundation offering a solution that circumvents consumer-focused changes while maintaining security advancements. As Google continues to lock down the Android ecosystem, enterprise strategies must evolve to accommodate these shifts, prioritizing Device Owner mode as a reliable management foundation.
