I recently discovered the Boldbeast call recorder, and have been very happy with it. So far, it's the only call recorder that works for the LG LS660 (Tribute) and LG LS665 (Tribute 2) Sprint prepaid phones.
Regardless, I recently upgraded to an LG LS675 (Tribute 5), and have been very happy with it. However, Boldbeast always fails to start a recording. I've been through all of the "Record Mode" settings (all the rooted options, too), and they all fail the same way. When I press the "Record" button, it tries to start recording (the Boldbeast icon appears in the notification area in white)...then it switches to red. When the notification is tapped, a "Boldbeast Recorder" message box comes up reading, "Cannot record calls, please change 'Record Mode' in settings and try again. (Note: you must uninstall all other recorder apps at first)" There are no other call recorder apps installed on the phone.
Is there anything that I could provide (logs/system info/whatever) that would help with this? As a programmer myself, I fully understand the need for specific details for any sort of bug tracking! I will be happy to send you screenshots of anything necessary.
