Never change phones

I spent an hour, and I am completely unable to move my conversations to the new phone. They have got this so that you can move your ID and your contacts, but you cannot move your conversations, so I’ve lost everything for the last year all because I bought a new phone! Total junk!

문자 자동삭제 기능

대화방 별로 보낸 문자 혹은 읽은 문자가 자동으로 삭제되도록 설정할수 있으면 더 좋을것 같습니다. 6시간 12시간 24시간 이런 단위로요!
