Google is introducing a new security feature in its upcoming mobile operating system, Android 17, aimed at preventing malicious apps from abusing sensitive system permissions. The update blocks apps that are not genuine accessibility tools from accessing the Accessibility Services API when a special security feature known as Advanced Protection Mode is enabled. The change is designed to reduce the risk of malware exploiting this powerful interface to steal sensitive information or manipulate device behaviour.
The feature has been introduced in Android 17 Beta 2 and builds on the Advanced Protection Mode first introduced in Android 16. This security setting allows users to place their devices in a hardened protection state designed to defend against sophisticated cyberattacks. When activated, the system prioritizes security over convenience by limiting certain device functions to reduce potential attack surfaces that hackers or malicious apps might exploit.
Under the new restrictions, apps that are not classified as accessibility tools will no longer be able to access the Accessibility Services API when Advanced Protection Mode is turned on. If such apps previously had permission to use the API, those permissions will be automatically revoked once the protection mode is enabled. Users will also be prevented from granting accessibility access to these apps unless they disable the enhanced security feature.
The Accessibility API was originally designed to assist people with disabilities by allowing apps such as screen readers, voice-based navigation tools, and switch-access systems to interact with device interfaces. However, cybersecurity experts have repeatedly warned that the same capabilities can be misused by malicious applications. Malware can exploit the API to read screen content, capture login credentials, monitor user activity, or perform actions on behalf of the user without their knowledge.
Because of these risks, Google has gradually tightened restrictions around accessibility permissions over the past several years. The latest change in Android 17 represents a stronger enforcement approach by completely blocking non-accessibility apps from using the feature while the advanced protection mode is active. However, legitimate accessibility tools identified with the appropriate developer flag will still be allowed to function normally.
The security update may also affect certain automation, customization, and launcher apps that rely on accessibility services to deliver advanced features. Developers and power users may therefore need to choose between enabling enhanced security protections or maintaining the full functionality of some third-party applications. Despite this trade-off, security analysts believe the change is an important step toward reducing the growing threat of Android malware that relies on accessibility service abuse.
Android 17 is expected to include additional privacy and security improvements as Google continues to strengthen protections across the mobile ecosystem. With cyber threats targeting smartphones becoming increasingly sophisticated, the company’s latest measures highlight the importance of restricting sensitive system APIs that can potentially be exploited by malicious software.
