My screen is locked by a virus and I cant tun it off
so I tried to download a video from instagram on an app called documents. I got a pop up on the app from scammers that listed a number claiming to be Apple tech support which I know is false. I tried to turn my phone off to see if the virus would go away and I am unable to. the screen is locked and I am unable to use my phone. all that works is the volume, power, silence and home button but I'm unable to turn my phone off. please help.
iPhone SE, I dont update my software often
