I have used WeChat for about a week only and uninstalled it then. I downloaded it for a change only. This app is not at all comparable to whatsapp, messenger or even hike.
It has so many features like chatting, calling and video calling but they dont work as smooth as in whatsapp or messenger.
Calling and video calling in Wechat are the worst that I have used ever. Also, on shaking it should show u the people in nearby area but it shows the results of china or korea . how the hell they are near! Dont even waste your time to have a try.
