This app was installed by Samsung/Android without my permission - It just appeared on my phone, and there is no uninstall option. Not a happy "customer".

안녕하세요. 모바일 T world 담당자입니다. 먼저, 이용에 불편 드린 점 죄송합니다. 모바일 T world 기본 탑재 단말의 경우는 삭제가 아닌 앱 숨기기를 통해 숨김 처리 가능합니다. 휴대폰 설정 → 홈 화면 → 애플리케이션 숨기기 → T world 선택 후 완료 부탁드리며, 해당 내용은 단말 기능으로 삼성 AS 센터로 문의 필요합니다. 삼성 AS 센터 1588-3366 이니 번거로우시더라도 문의 부탁드립니다..

The only disaster app of my Android experience. Once installed can never be removed, EVER! Took control over everything and NEVER let me use root of the Samsung Phone. It works as the agent of SKTelecom to ruin android authority over Samsung in South Korea.
