How Shizuku is used

Can record phone calls with system audio via `app_process` scrcpy server through Shizuku.

This is an AI-assisted analysis of Shizuku-related usages in the app's public source code. It is best effort, so it may not catch every single usage.

How this app uses Shizuku

Shizuku is used to capture both sides of a phone call with system audio for call recording.

Record phone calls: during a call the app starts privileged audio capture through Shizuku, which launches a bundled audio server with the system call audio feed and saves the result as an audio file in the recordings folder, retrying with the microphone based voice communication feed when the call feed is unavailable on the device.

Android APIs or commands used

app_process

Notable details

If Shizuku is unavailable or disabled, the app still records with the normal microphone based recorder, so recording works without Shizuku at lower quality.
