Whatsapp is very famous app and almost every android phone user using this app. I don’t like this app so much because there is nothing to change in this app. like.
no theme to make it more attractive.
no stickers to make chat more enjoyble.
no changes always same.
no video call facility
If you will see other app they will give you other attractive and useful facility to make chat more enjoyable.
I am using whatsapp just because its famous and almost everyone using this app. you can connected with everyone
