WhatsApp is a social network by virtue of any sort of message is sent or receive in between two social users and more than two social users. it is also able to provide voice call via internet connection, at there sometimes call is interrupted due to lower internet speed and somehow not good design of whatsapp and at present whatsapp became bad to voice call and zero percent efficiency.
And just now add a new video call feature, where quality of pixels is not good so that use of whats app, video call can not be done with good pixels resolution of video calling from one whatsapp user to another to cause of it marketing value of whatsapp somehow is going to decrease. when it opens in a android smartphone then it takes more time to open and new contacts can be refreshed very past than other messengers. one most complex thing is that when we take a photo of something through camera when we have opened it.
in icons box that indicates various symbols for various expression just like happiness, sad, worries, and so many others are available but some of expressions whatsapp has missed and it is major problem of whatsapp that’s why it is losing a few whatsapp users. sometimes a photo is uploaded by a user with a caption, where as added caption is become combined part of photo or video. then if we wish to remove added caption wherever caption can not be removed.
if we talk about grouping system then whatsApp is to be a app that is not fulfilling wishes and requirement.
