Need to look that up. The Samsung S8 I have is OK as I put it on total silent mode when recording a meeting. However, I have to remember not to have it face up, because a blue light shows when recording if screen is on and for some odd reason, recently the mic has been having issues picking the voices up despite working fine so then the Samsung software can't detect audio it pops up a big, bloody message on the screen even when phone is locked.
