I must be going crazy. I’d swear while driving today; Heard a phone pickup beep. Asked Better Half if she heard it and she said, “Let me check my phone”
Probably lost signal or regained connection.
Android foans beep in response to both.
Mine is on vibrate, so it only beeps through the earpiece.
Signal bounces here like an angry kangaroo.
Or a jerboa on crank.
