Worthless. Worse than useless. I wish Thailand would get rid of this POS crapware. Stupid thing never gives notifications, unless I just drift to sleep after forgetting to turn my phone off. And then it will be about old messages. Damn thing refused to tell me I had messages today. Nothing's changed in years so they obviously don't care. I have no choice because of network effects. Switch to KakaoTalk or something less malicious.
