Android 17 Blocks Apps from Detecting Developer Mode

Google has quietly blocked apps from accessing the status of Developer Options and USB Debugging in Android 17, a move that could impact how users interact with certain apps.

The change was discovered by developers who noted that apps would no longer be able to detect whether Developer Mode is enabled on a device, with Google stating directly in code commit notes that such information is not necessary for apps.

Developer Mode allows for debugging interfaces and communication between devices and development tools through the ADB protocol, but it also exposes system settings and can introduce security risks if misused by malicious apps.

In an effort to mitigate these risks, some apps will now actively detect whether Developer Mode is enabled on a device, terminating their processes or prompting users for exceptions if it is detected.
