We have a Wileyfox Swift 1st Gen running stock Android 7.1.2.
No matter what settings we try the recorder simply won't work. It fails with the "there can only be one recorder" message.
It seems something is either hogging or denying access to the microphone.
The device is stock and *not* rooted and we would like to keep it that way if possible.
If you have the same or similar device then please help us work this problem: how do we find out where the stop is.
If on the other hand you have rooted your device and got this to work, then please tell us which root tool you used.
Thanks.

I have received your log files and checked them.

There is something in your phone occupying the microphone, as a result all recorders in the market can't work, you can test and confirm the fact yourself.

You should find out the app occupying the microphone, and remove it. If you don't know what app is occupying the microphone, I suggest you reset the phone to factory settings to remove all apps, then test again. If the problem is still there, that indicates the app is inside the ROM that is made by the manufacturer, so you can't remove it. In this case please ask the manufacturer for helps.
