Moto X4 Android 7.1.1 doesn't need root, it records calls loud and clear in two sides.
Please use these settings to record calls:
- Record Mode: 1 or 5
- Record Format: MP3
- Tune Audio Effect: No
- Tune Audio Route: Group3
Android 8.0 Oreo
If you have upgraded the ROM to Android 8.0 Oreo you must have found all recorders in the market no longer work well - in recordings the caller's voice is weak.
The good news is, Boldbeast Recorder V11.1 can fix the problem perfectly, no root needed, just install the app and go, recorded calls are crystal clear in two sides.
We have just released the new version V11.0. Google Play may need some time to publish it, if at this moment the new version is not available in your area please download it from our web site: https://www.boldbeast.com/android/call_recorder.html
After installation please click "Set Default Settings" in Boldbeast Recorder, then it works at once.
