Hey there, I am using WhatsApp from past two years and now I am thinking ro quit WhatsApp for some issues.
The main problem of WhatsApp is there is not delete chat feature for everyone. If I send anyone any message by mistake then I cannot delete the message from the recipents phone. This is why I faced many problems for this. The another main problem of WhatsApp is if any admin of any group quit his own group Whatsapp selects randomly any person and make him admin. It is a very bad feature.
For this reasons I am quiting WhatsApp finally. If you are thinking to engage yourself in a messaging app then I recommended you to use any other messaging app instead of WhatsApp
