I only wish to change some of user interface to make an easy for people to change from phone to speaker
And to choose video or voice. Easy
User interface development process



I just hope you will continue improving the app, its like FaceTime almost of apple, one more thing I notice is, while using the app it causes my device to heat fast and also drain my battery faster, I hope u guys can fix this issue
