options again, and set selinux to permissive.
I have a Galaxy S5 rooted, this was working great until a few days ago. I've done this many times and it still doesn't record and I still get this error message. Any help would be appreciated
Your Galaxy S5 has KNOX inside, because of it the selinux is set to the enforcing state, so Record Mode 21, 22, 23 and 24 in the app don't really work.
In V7.5 and older versions if Record Mode 21, 22, 23 and 24 don't really work it uses Record Mode 1 to record calls, no error message displayed.
In V7.6 and newer versions it displays an error message. In this case you can change to use Record Mode 1, or set selinux to permissive to make Record Mode 21, 22, 23 and 24 really work.
thank you! it worked!
