TROUBLESHOOTING:

Problem: BSR records for a few hours in background, then stops.

Solution: Check your phone's power saving settings. Make sure the BSR app is "protected" and is allowed to work in the background indefinitely.

Problem: BSR doesn't start up when I reboot the phone.

Solution: Make sure that you had started the recording before you turned off the phone. Check if BSR can be found in the list of running apps (Developers' Options) after startup (without clicking the BSR icon). Check your phone's settings for "optimizations" that might block apps from running on startup. Try making the BSR app "protected".

Problem: Very bad sound quality even on highest settings

Solution: Make sure that your microphone is not obscured. Check if a leather or plastic casing of the phone obscures any of its microphones. Record a short audio speaking or knocking to different parts of your phone to find out where the most sensitive microphones are located. If the mic is on the bottom, put the phone up side down in the pocket so that the mic sticks out. Try an external microphone. Try a different phone, more expensive phones tend to have better microphones.

故障排除：

问题：BSR在后台记录了几个小时，然后停止。

解决方案：检查手机的省电设置。确保BSR应用程序处于“受保护”状态，并且可以无限期地在后台运行。

问题：重启手机时BSR无法启动。

解决方案：确保在关闭手机之前已开始录制。检查启动后是否可以在正在运行的应用程序列表（开发人员选项）中找到BSR（无需单击BSR图标）。检查手机的“优化”设置，这些设置可能会阻止应用在启动时运行。尝试使BSR应用程序“受保护”。

问题：即使在最高设置下音质也非常糟糕

解决方案：确保您的麦克风不会被遮挡。检查手机的皮革或塑料外壳是否遮挡了任何麦克风。录制简短的音频说话或敲击手机的不同部分，以找出最敏感的麦克风所在的位置。如果麦克风位于底部，请将手机朝上放入口袋中，以便麦克风伸出。试试外接麦克风。尝试不同的手机，更昂贵的手机往往有更好的麦克风。
