It needs constant updates which it doesnt improve, there are a lot of bugs 1. The call just drops or just reconnecting 2. There are messages that cant be seen but there is a invisible message I need to close the app before it functions properly. 3. When playing a 2 minute or so video the bar line of the video is on the screen and it doesnt remove unless u close the app and re open it again. Since there is updates i hope there is an IMPROVEMENT NOT BUGS
