How to record PW sound

*The heart beat sound (in PW mode) cannot be directly recorded via Leltek app due to OS authorization limited.
*We would recommend using other method, for example, usage of iOS inherent recording (can be found in shortcut) or android record app to record the sound. 

This is a sample video by iOS:

The shortcut of screen recording show up if you scroll from top-right corner down to center. Then start recording. The sound can be recorded with this iOS inherent function of screen recording. https://support.apple.com/en-us/HT207935 from apple website

If android, we will recommend the customer use “xRecorder” (screen +sound recorder to record that)
