Which devices may not block internal microphone?

Currently no confirmation of any mobile device manufacturer found , confirming that if external microphone is inserted , internal microphone is blocked and can not record.

If such data will be published it will help users to be sure that their device is secure...

Looks like that some devices allow internal and external microphone works simultaneously or may not recognize external microphone ( so internal may work) , examples below: ^[1] ^[2] ^[3] ^[4] Davidy2001 (talk contribs‎) 12:56, 26 November 2018‎
