1. Due to microphone limitations on different devices the meter range is different, usually the low end of the scale cannot be achieved because of the microphone noise and the upper end of the scale is limited by the microphone distortion on high levels.
2. Devices employing AGC (Automatic Gain Control) will have significant measurement errors and limited range. This is not app's fault.
3. If sound meter stops working after the notification or vibration come then please exit the app and start it again.
4. The graph may take time to start plotting the values.
