BCR records phone calls on supported rooted Android systems as a basic call recording application.
About BCR
BCR (Basic Call Recorder) is an open-source Android app that records incoming and outgoing calls in the background once enabled. It is designed for rooted devices or devices running custom firmware, is installed as a system app, and works on Android 9 and newer. The project deliberately stays minimal: many features, such as workarounds for OEM battery optimization or support for unrooted stock firmware, are out of scope by design.
Key features
- Automatically records incoming and outgoing calls in the background
- Output formats: OGG/Opus, M4A/AAC, FLAC, WAV/PCM, AMR-WB/AMR-NB
- Stereo recording with separate uplink and downlink channels
- Records to SD cards and USB devices via Storage Access Framework
- Auto-record rules and a quick settings toggle
- Supports both Magisk and KernelSU installation
Best for: Android users with rooted devices or custom firmware who want a minimal, automatic call recorder.
Good for
- Open-source project with a deliberately simple, low-maintenance scope
- App requests no network access permission
- Direct boot aware, so calls can be recorded before the first unlock after a reboot
- No persistent notification unless a recording is in progress
Watch out for
- Requires root or custom firmware; stock unrooted firmware is not supported
- Stereo uplink/downlink separation is only known to work on Pixel devices running newer Android versions
- No workarounds for OEM-specific battery optimization or app killing behavior
- Support is dropped for older Android versions when maintenance becomes cumbersome

BCR FAQ
Which Android versions does BCR support?
Android 9 and newer.
Does BCR work on unrooted devices?
No. It is for rooted devices or devices running custom firmware, and it must be installed as a system app.
Does stereo recording work on every device?
It is only known to work on Pixel devices running newer Android versions. Other devices may not separate uplink and downlink, or may produce no audio at all, so test calls are advised before relying on it.
