Call recorder for Galaxy S4 SGH-I337 (No root needed)

My phone is that exact model. I have Boldbeast version 7.1 registered. Record Mode was set to 4 by default at install and Record Format was AMR by default. But what are the Tune Samsung settings? I do not see them anywhere. It is working perfectly, but I was just wondering what they are and why I don't have them.

Yes, I did test a LOT of recorders and it was always the same thing. I gave up until this past week when I found yours. It is a godsend and I love it. I had a Pantech phone that had a Record button whenever you were on a call and you could press it at anytime to start and stop a recording of both sides. I got spoiled by it and wanted the same thing for my S4. Now I do. Thanks again.

Please set Tune Samsung 3 to "Enable Group 1" for following Android versions, it records calls perfectly.
Galaxy S4 SGH-I337 Android 4.2.2
Galaxy S4 SGH-I337 Android 4.3
Galaxy S4 SGH-I337 Android 4.4.2

Please set Tune Samsung 3 to "Enable Group 2" for Android 4.4.4, it records calls perfectly.

Thanks to Thomas Mitchell, he told us "Enable Group 2" works well for Android 4.4.4, if you use "Enable Group 1" you may meet following problems:
"the first time you dialed a number it would not go through but when you redialed it the call would go through. Other symptoms indicating a problem was that Boldbeast would not stop recording sometimes for a full minute or two after you ended the call. On an occasion or two it would give an error when you started to record either in memo mode or when attempting to record a call. The problem would exhibit itself whether you had it set to Manual or Auto recording. Funny thing was, when you dialed a number that didn’t go through, Boldbeast would indicate it was recording and the phone timer would start as if the call went through and when you hung up if you chose to save the recording then when you played it back you would hear the other side speaking even though you heard nothing on when the call was happening, and you couldn’t hear your side at all on the recording."

I don't know if this will help in troubleshooting or not, but I am going to mention it anyway. The volume for everything will be reduced to minimum, not just ringtones. Alarms, notifications, everything. And it still shows that it is on full volume too. But despite that, the volume will be so low that you cannot hear it unless you hold the phone up to your ear. But as mentioned, if you go back to version 7.1 you will not have any of these problems.

================
We have just released Boldbeast Recorder V7.7, it fixed the problem, now SGH-I337 works great.
Cheers!

I am using the registered version 7.9GP and while the recording works perfect with the settings mentioned in the post the volume for all everything went down significantly. Is there any way I can revert it back?

I had to reinstall the app, as the callers could not hear me at all. I wil get back to you if I run into issues again. thanks for the reply.
