As a Vietnamese, don't use this app. It's popular mainly due to nationalism and support for domestic products, not quality. Unlike normal chat apps, it stores everything locally on your device, filling up storage, deleting the app deletes all your chat history. It's riddled with system pop up ads notification disguised as ambiguous messages to inflate engagements (eg.You have new messages!) forcing you to either tolerate spam, open to check, or silence the app and risk missing actual messages.

This app has bug, please fix it. It does not ring at all during Do Not Disturb even it was allowed. The Facebook Messenger and Phone calls are ringing fine when allowed in Do Not Disturb.

This app is terrible. It uses your phone’s storage to store its own data, taking up a huge amount of space on your device. We end up losing so much storage space because of this poorly designed app.
