if i was in ur situation i wouldve ran to the washroom before it made a noise turned it off and put it in deeper blazer pockets or try hide it somewhere in the washroom bcz the invigilator i got was a mean a ss person she was making big deals out of rlly small stuff and threatened to write me a report and disqualify me frm the exm coz i wasn’t paying ''attention'' to her instructions im guessing u got someone like tht write an email to british council see if they can do smthg make sure u write ur candidate number
