Taking about concept of whatsapp messenger is a nice choice to stays connected with your friends and loved one via internet .But being a modern day messenger whatsapp lack some of the following aspect:
1." Moving out permanently form a particular group":Its quite irritating to be in some groups because of unwanted sharing of unwanted trolls, videos and musics or files. If you exit the group the other members who are admins again add you in the group which is also irritating .Thus whatsapp messenger must find a solution to tackle such situation.
- "Offline messaging features are also missing": Yes offline messenger can be consider as modern day messenger feature. If your device is connected to internet and your friend’s device is not but your friend is in network range so you can send your friend texts messages as that your can do in "hike messenger".
Thus if some one wants a modern day messenger I will recommend "Hike Messenger " not "whatsapp messenger"
