I got a mi max 3 with miui 10 8.8.3 china rom
The screen recording app does not have the option to switch to system sound , i got mute and mic option
anyone with mi max 3 could check their screen recording app and tell me if they have an option to select the system sound please
If the have an option which rom they use.
