Random devices connecting to bluetooth on iphone XR
Whenever I use bluetooth, random devices keep connecting to my iphone XR such as 'Edward's A12','Pixel 8a' or 'iPad'. This happens specifically in college which constantly freezes and switches off my music, and these devices never have the little i icon to forget them. Is there any way to permanently get rid of them, or block random devices from connecting to my phone?
iPhone XR, iOS 18
