Huawei Mate 20 Pro, does it work without root?

2

Huawei Mate 20 / Mate 20 Pro 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 if you root the phone.

After root the phone please use following settings to record calls:

- Record Mode: Alsa
- Alsa Device: Auto
- Alsa Bits: Auto, 16 Bits
- Alsa Channels: Auto
- Alsa Sampling Rate: Auto
- Fix Recording Issues - Change Audio Controls: No
- Fix Recording Issues - Change Audio Driver: No

Great news! Thanks to Kuldeep Clair, he figured out following settings in Boldbeast Recorder works well:

- Record Mode: 12
- Fix Recording Issues - Tune Audio Route: Group1

Recorded calls are clear in both sides, no root needed.



Update 2018-11-27
===============
Some users confirmed settings suggested by Kuldeep Clair above work great without root. However some users reported their phones still don't work well with the settings.

The manufacturer enables or disables features according to market areas, therefore the ROM is a little different from country to country, from area to area. This is the reason why in some countries the settings work great, in some countries they don't work. If they don't work, you should root the phone and use the Alsa settings above.

Any ETA when non-rooted variant could be available? Or is it a limitation of Android 9.0? At the moment there is AFAIK no known public solution how to root the device.

I'm afraid there will be no solution without root. Android 9.0 limits the call recording feature very strictly, it's impossible to bypass the limit. Root is the only way to go.

If suggested settings by Kuldeep Clair still don't work for you, I'm afraid you should root the phone.
