Google Pixel 3 / Pixel 3 XL Android 9.0 need root, otherwise you can only record your own voice, the caller's voice is very weak in recordings, no matter what recorder you are using in the market. Boldbeast Recorder can fix the problem perfectly if you root the phone.
After root the phone please use following settings to record calls:
- Record Mode: 1
- Fix Recording Issues - Change Audio Controls: Yes
- Fix Recording Issues - Start Input Stream: No
Or use these settings to record calls:
- Record Mode: Alsa
- Alsa Device: Auto
- Alsa Bits: 16 Bits
- Alsa Channels: Auto
- Alsa Sampling Rate: Auto
- Fix Recording Issues - Change Audio Controls: Yes
- Fix Recording Issues - Start Input Stream: No
Recorded calls are crystal clear in both sides.
Update 1
=======
Some users said the recordings sound like "slow motion" or like "fast forwarding" using the Record Mode 1 above. This indicates there is a bug in the AudioServer inside your ROM - sometimes the AudioServer wrongly resamples the audio stream and that made the problem. In this case please use the Alsa settings above to record calls. The Alsa engine is made by us, it doesn't rely on the AudioServer, so it can perfectly bypass the bug.
Update 2
=======
From users' feedback, in some market areas (for example China mainland) the call recording feature is not disabled by Google. In this case no root needed, just install Boldbeast Recorder and go, recorded calls are very good.
Update3
======
Pixel 3 / Pixel 3 XL have a new feature named ""Call Screening", some users said the feature doesn't work well when the recorder is working. Please change following settings in Boldbeast Recorder to perfectly fix the problem:
Call Settings - Incoming Calls - Auto Detect Answered State: No
Call Settings - Incoming Calls - Answered State Delay (Seconds): 3
