It was already installed on my new Samsung phone. Right after I enabled it by following instructions, granting access to my phone's contacts, microphone, usb storage,... it sent an install message to my contacts, and installed itself on my contact's phone. It behaves like a malware. Also, it is popping up advertisements on my screen. I did not have time to experience if this app is useful or not. I am uninstalling this right away due to obvious security issue and lack of privacy respect. bye bye.

Adware. It inserts ads in message. Also constant crash. Freeze. Spam block doesn't work well.

안녕하세요 후후이용자님 광고가 많이 불편하시다면 하기 경로를 통해 통화종료/부재중 알림창을 off 후 이용해 주시기를 부탁드립니다. 1. 전화알림 후후 앱 실행 > 설정(우측하단)> 전화 알림 > 후후 알림창에 표시 > 전화알림창 실행 > 통화종료/부재중 '실행 안 함' 2. 문자알림 후후 앱 실행 > 설정(우측하단)> 문자 알림 > 문자 알림창 '실행 안 함' 참고로, '광고없는 후후'정기구독시 후후앱을 광고없이 이용하실 수 있습니다. 후후 서비스를 이용해 주셔서 감사합니다. 후후팀 드림

UI looks horrible and cluttered, and only 1/4th of the app is translated (it would literally cost less than 10만원 to get these simple words and sentences translated) but I'm interested in the features so I'm reserving judgment for now. Off to a bad start though.
