Worse... App... Ever! I don't use this app but I had people ask if I can help. Nope! I almost threw the phone in frustration. Main issue is getting the verification code that never arrives! If I can't get pass that, how am I supposed to register for an account. And recovering password. Mind as well just give up and use another app that is user friendly.

Absolutely horrendous excuse of an app, for some unknown reason it takes up around 20 gigabytes of storage on my device, sometimes the message sent to me just doesn't trigger a notification, files sent on the chat can just cease to exist after a period of time and you couldn't download them. I have absolutely no idea how the majority of the Vietnamese population could use this thing and not messenger or telegram or something.

This app is very restricted and doesn't have necessary functionality of a messaging app, the messages will be disappeared randomly when I travel and photo quality is very low (not even a megapixel). In-app purchases and subscription is needed for your data retention. They also disabled your account randomly without consent. Some international credit cards are not accepted for payment. New Terms of Service stated that they have all rights to sell your data to third-party, please be careful.
