Blue status bar with gear and rotating arrows?
Appeared on iPhone SE2, iOS 18.2 while scrolling through social media comments in Safari over LTE. Nothing plugged in, not screen mirroring or hotspotting, automatic updates off, location services off, etc. etc. No apps running in the background afaict.
I then closed Safari, turned on Airplane mode, yet blue bar + symbol remained. Tapping the bar did nothing. Rebooted the phone and it went away.
Never seen this before in my life. Kind of creeped out. Any ideas?
