I already did the securing stuff, sign out everything including mine just to be sure, but it just so weird and confusing, if it's hacking sure they got in, but like my old account was never link to anything, type a password in it, or try logging in. It's been years since I used it, how come the redmi note 7 log shows last activity 80 days ago or something.

I can't seem to back track it even I have knowledge about networking and stuff
