It has many problems and bugs the picture and video quality is very very poor and it is very important thing for video calling it is always blurred u even can’t see in such good Internet connection so plz fix it up all this problems it lags at some times so it can be better. The layout and design is also very bored of the imo it can be improved and can be even better as it now. The quality of video should be improved rather than it is not useful and worthy.
