Upgrade Android REC application

There is a call recording application for Android developed by our company,

Along with OS update (Ver 6.0 or later)

The acquisition of the other party 's voice became unstable, and it became impossible to take recording at all by the environment of the opponent.

I tried all published all audio APIs, but it does not work well.

I thought It seemed that it became impossible due to specification change,

but Even in the latest environment there was an application that was able to record all calls clearly.

In this application there is probably no problem so there should be a way

I am looking for someone who can update the our recording application just like this.

There is already an application, and it will be in the form of updating it.

It is a requirement to be able to record phone calls stably with

AondroidOS Ver 7.1.1 or later

Thank you for your consideration.
