The imo is one of the best app which works in india and as well as in arab countries
It has both voice calling and video calling feutures
But I have one problem that if we type any msg the opposite person can see that what we are typing
some times we will type some thing and thinks that we should not send these and again we will delete it but in these application the opposite person is knowing every thing that what we are typing
You need to remove these feuture
