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.

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. 😔

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.

Mamy nice features. A little less clear how to greenlight previously flagged numbers, e.g. kt english service gets all kinds of warnings but I really wanted to talk to them and they were legit!

Fantastic app that really proves useful in Korea. It really filters out the riff raff and helps me block unwanted spam. I hope to see this in other countries!
