All over the function of this dialer app is very good and easy to use, but one thing is strongly needed to change that call recording when in action it announces a sound "call recording has been on/ended". This sound is audible to the caller/reciever whom I talking to. Also the file is not saved in the files manager unable to accesss it later. I strongly recommend to put the announcer tune off and also save the file in the files manager. The responsible team read this take into Cosideration.
