Recording phone calls - where is the file?

[avhakola]

Why wouldn’t it be safe?

If you want to copy the original file, @tuplasuhveli already told you how to find the files:

@tuplasuhveli

If you want to access the file itself, enable developer mode and write this command on CLI:

devel-su

and enter your password. Then:

cd /home/defaultuser/.local/share/system/privileged/Phone/CallRecordings/
