Hello friends,
whatsapp is the oldest online chatting application we know, and it was very good until it was takeover by facebook inc.
From that time its updates are coming almost every month and they are way too heavy.
My phone always hangs just because of whatsapp itself and I have uninstalled it many times but have to retrieve it again and again.
The reason behind retrieval is that around 80% of my contacts uses it.
Talking about its voice & video calling feature, both of them are useless, quality of video call is pathetic and voice calling is also not upto the mark.
Whatsapp is necessity now a days otherwise the qualty of features are not that good.
