As I already told in the review on the instagram app .as like my 2 nd fvrt app is watsapp the clarity in the video call and voice call is super .we can put the status .when strangers come to chat with us unknowingly we can block them .for business purposes watsapp is improving daily .and even the teachers are not giving notes .notes are shared in to the watsapp? .technically all have been improving .for soul mates without any delay they canmsg quickly limited mb is needed .all should use it .its being wonderful app all should try it.?
