Non-features

As the name alludes, BCR intends to be a basic as possible. The project will have succeeded at its goal if the only updates it ever needs are for compatibility with new Android versions. Thus, many potentially useful features will never be implemented, such as:

• Support for old Android versions (support is dropped as soon as maintenance becomes cumbersome)
• Workarounds for OEM-specific battery optimization and app killing behavior
• Workarounds for devices that don't support the VOICE_CALL audio source (eg. using microphone + speakerphone)
• Support for direct boot mode (the state before the device is initially unlocked after reboot)
• Support for stock, unrooted firmware
