Starting with Android 10, Google killed call recording by default and on May 11, the company is implementing new Google Play Store policies preventing third-party apps from using the Accessibility API for recording the call audio stream.
Those changes are towards improved privacy and security as call recording laws across the world vary quite a bit. However, system, pre-installed apps that already have permission to tap on the Accessibility API won’t be affected by the change.
Pixel’s and Xiaomi’s dialers, for example, are two exceptions to the rule. This is considered a native call recording functionality. And although Google didn’t disclose plans on taking care of those as well, we would assume that some additional policies will be implemented in the future.
