Apple’s latest iOS update (26.4.2) fixes a critical security flaw that allowed deleted push notifications to remain accessible on iPhones and iPads – and law enforcement agencies like the FBI reportedly exploited it.
Key takeaways:
✅ Update now if you’re on iPhone 11 or later, or eligible iPad models
✅ Deleted notifications were unexpectedly retained on-device
✅ The FBI used a tool to view local Signal data post-deletion
✅ Signal asked Apple to patch this – and Apple finally did
✅ EFF: Limit notification content on the lock screen for extra privacy
🔒 Worried about your notification privacy?
Go to Settings → Notifications → Signal (or any sensitive app) → disable “Show Previews” or set to “When Unlocked.”
