Please disable the "Start Input Stream" option to avoid the problem in your LineageOS 15.1.

I edited my post. Disabling it makes it not crash, but audio is still heavily distorted and doesn't seem to record the other side. (Can't tell 100% because of the distortion though)

EDIT: With Start Input Stream off and using the second recording preset posted in the OP this is the quality I get. I can hear the other side.

Will be happy to buy the full version if I can actually get this app to record in good quality

I currently use lineage-15.1-20181122-nightly-bullhead-signed.zip, with appropriate vendor/radio/bootloader images. I rooted via LOS addon, Adaway works just fine, and seemingly even this app.

What doesn't work however is that at the end of the call, if it is being recorded by boldbeast, the call won't die. It will actually terminate the call but the screen will just get stuck saying "terminating" and the only way to get rid of it is forced reboot.

EDIT2: Looks like enabled Start Input Stream is the culprit. If I disable it, the audio records but heavily distorted, and seemingly only one side.

Tried to use the following settings to get the crash:

EDIT: Another bug - resetting settings to default will keep Record Mode set to Alsa instead of reverting to default. It also keeps root access, but I guess that is fine.

Great, thank you! This really helped!

I have an error, that "Unable to open database."

The reason and the solution: https://www.boldbeast.com/forum/topic16 … error.html

I wrote you in feedback. Now, I decided to write a post here, just because my issue is still actual.

My Nexus 5x has a root. I've installed the call recorder and even could successfully  record one call. Then I accidentally uninstalled the app.
After installing it again I have an error, that 'Unable to open database. Please reinstall the application (something like that in English, I'm from Russian location).

I reinstalled the application dozens of time, cleared the cache. Google doesn't backup the data for this application. I tried the older version. However, without any success.

Please help.

Now that Boldbeast has the root access, can't it do something to fix the problem directly?
No, it can't unfortunately. To fix the problem we need to talk to the baseband, but the baseband has no public APIs for third-party developers to use. Qualcomm (the baseband manufacturer) provided proprietary APIs to LG, so LG can use the APIs to fix it but we can't.

sounds distorted, please can you share properly configuration.
Seems that it is first complain about Boldbeast performance on Android Oreo.

@chavocarlos, were you able to eliminate or reduce distortion? I'm having the same problem. My voice is clear, incoming voice is loud and distorted. And no "Enhanced 4G LTE Mode" option to turn off.
@boldbeast, can you share the config you gave to @chavocarlos. Thanks.

Because the ROM doesn't provide interfaces to programmers to do so.

Ok, any advice, what parameters to play with, to try to improve this situation?

Everything is latest: Boldbeast Recorder v.11.0, Android 8.1.0 with April security patch. The mic gain is way too high, the other party's voice is distorted. Why not let users adjust it on their own?

Because the ROM doesn't provide interfaces to programmers to do so.

For example,
- if Boldbeast asks the ROM "please tell the baseband to unblock the caller's voice in the capturing stream" the ROM says "OK".
- if Boldbeast asks the ROM "please tell the baseband to decrease the caller's volume in the capturing stream" the ROM says "No, I don't accept the request".

I can record without any problem until i activated the proximity sensor when i put my ear on my phone and the screen going black which result with 8min call to only 30sec recording file for example.

If i turn off the screen manually or using speaker or just keeping the screen on, the app records everything. It's only when the proximity sensor is activated that the recording going bad.

Has anyone experience the same problem i have with their phone?

The previous configuration don't work well on Nexus 5X with Android Oreo September Security Patch, sounds distorted, please can you share properly configuration.

Can you please:
- send a recording to me, let me listen to it.
- click the "Call Settings - Fix Recording Issues - Ask New Parameters" item in Boldbeast Recorder to send log files to me, let me have a look at them.
Thanks.

It seems Nexus 5X Android 8.0 Oreo works very well, so far no one complain about it.

Android 8.0 needs root.
Please update Boldbeast Recorder in your phone to the latest version (currently V9.7). The MP3 format is supported now.
