Automatic Call Recorder
Record any phone call you want and choose which calls you want to save. You can set which calls are recorded and which are ignored. Listen to the recording, add notes and share it. Integration with Google Drive™ and Dropbox allows calls to be saved and synchronized to the cloud as well.
Google Drive integration works on Android versions 3.0 and above.
Please note that call recording does not work on certain handsets and can result in inferior quality recordings. We therefore suggest that you try the

Call Recorder

free version before purchasing the paid app.
If you encounter any recording issues or wish to improve voice quality, try recording from a different audio source, or use auto-on speaker mode.
