Interface completely in Korean and cannot be changed. Intrusive ads throughout the app. Does not detect spam or previously blocked calls at all. Wants overreaching access to your data and provides virtually nothing but ads in return. TPhone app is hands down better in every way. Hate that Fold 4 with current carrier forces this down your throat to use the Bixby Call feature. Horrid app. Uninstalled a 3rd time. Keep hoping it will improve, only to be seriously disappointed. 😔

안녕하세요, 함께 쓰면 더 좋은 후후입니다. 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. 더 나은 서비스 제공을 위해 노력하는 후후가 되도록 하겠습니다. 감사합니다.

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.
