I had started use this app from my collage life. now I complete 6 years with whatsapp. and whatsapp never dis pointed me. I like it.it wasvery very important to now for all. but some feature I think will change and even make batter than now. like theme, sticker, characters etc. but after all whatsapp is very useful to connected with friends family and relative. now whatsapp is updated and we can also do free call. the call quality is very poor as compare with other free call apps. but it’s ok to use. and nice app.we will hope now the whatsapp give some new surprise and something new to us.:).
