I have been using whatsapp from a very long time of 5 years. The old version of this was much better in working field and type of smileys used.But the newly upgraded has a worst choice and disgusting smileys .The smiley should be lovely to see and send others but in this it is over exaggerated and made sense less.The other new feature is message deleting option after sending also , this is the most stupidest and unnecessary feature. This does not have a proper security for example if I send a msg and then delete it and can pretend that I hav not sent any msg to him or her.Overall performance is quite good but it gets its server down which also happend in the new year day which is unacceptable and annoying.
The audio calling the voice is not audible in most of the cases and holding of calls takea place un nesesarily.
The video calling is also poor compared to other video calling applications.
