Here’s the crux of the article in video form

New updates are being added at the bottom of this story…….

Original story (published on January 30, 2023) follows:

The recently released iOS 16.3 update introduced Security Keys for Apple ID, along with other enhancements, bug fixes, and security updates for the iPhone.

It also adds support for the 2nd generation HomePod. The update also addressed some issues where the Lock Screen’s wallpaper sometimes appeared black and Siri did not properly respond to music requests.


However, it appears that the update has introduced some bugs as well, which are affecting one’s ability to use the phone properly.

Notifications not working or don’t show up in iOS 16.3

According to reports (1,2,3,4,5,6,7,8,9,10), some iPhone users are facing an issue where the notifications don’t pop up on their device after the recent iOS update.

Some claim that even though both the in-settings and in-app notifications are turned on for their Gmail app, they are unable to get any notifications for emails received.

Another user on Reddit complained that they don’t get any WhatsApp notifications unless the app is opened.


iOS 16.3 is so awesome it locked up my iPhone on reboot as I was typing in my code. Still can’t get notifications for Apple messages on my Apple Watch. Great work @AppleSupport

iOS 16.3 major notification issues across calls, WhatsApp msgs, iMail. Any idea why? @Apple @AppleSupport

Even though re-installing affected apps on solved the problem for some time, the issue often pops up after a while. Also, this issue is now affecting other apps as well.

Some have even tried resetting the apps and their smartphone but to no avail.

Notifications not playing sounds

Some iOS 16.3 users (1,2,3,4,5) are also complaining about an issue where neither the notification is displayed, nor sound played.

A user complains that they face this issue when Bluetooth is turned on. It is alleged that this issue affects different iPhone models.


Updated last night and now I have zero notification through headphones or speaker. Cycle silent switch does nothing. Force reset nothing all notification setting look unchanged. Volume maxed out. Coming from iOS 14 on an xs max this 14 pro max is like a windows 98 computer

I have a 13 pro max, just recently my notifications have no sound. I have tried everything and still none of them have sound. Any ideas?

This glitch is preventing users from getting access to sensitive notifications for emails, messages, and much more.

iOS 16.3 Jittery/stuttery notification center

Some (1,2,3,4,5,6) are also facing an issue where the notification center appears to be jittery or stuttery for some. The problem is affecting different iPhone models.

Users also complain about the lag and screen flickering issue in the notification center. Also, when one expands or swipes up to expand notifications, its appearance stutters a lot.


Anyone else experiencing problems with iOS 16.3? Cause I’ve been having issues with the Notification Center being delayed and lagging also the performance is absolutely unstable.

Does anhyone else encountering a lag in the notification centre? More specifically, in home screen when you swipe up to show you the notification centre, the bar “notifications centre” goes up and then down.

No official response

Unfortunately, Apple has not officially responded to the matter, but we do hope that they acknowledge and fix the notification glitch soon.

That said, we’ll keep an eye on the issue where notifications are not working or broken for some iOS 16.3 users and update this article as and when something noteworthy comes up.

Update 1 (February 14, 2023)

12:38 pm (IST): Some users are reporting (1, 2, 3) that the issues with notifications persist even after iOS 16.3.1 update.
