I’ve encountered a UI/UX “soft lock” issue involving the GNOME Lock Screen and iOS device mounting. If the screen is locked and I connect my iPhone to charge or sync, GNOME detects the device and triggers a mounting notification (“Device Locked: Please unlock your iPhone to trust this computer”).
This notification banner overlays the password input field, making it difficult to click into the prompt or see what I am typing. To my mind, the notification should not appear at all until the session is successfully unlocked.
As a temporary fix (being a newer user), I found that I can go to Settings → Notifications and toggle “Lock Screen Notifications” to OFF. While this stops the iPhone prompt from blocking the login, it is not ideal as it hides all other useful notifications as well.
