Perhaps as many as 999,999 out of a million people think that an "update"
to Android is only in the Android version number; but that's not the case.

Android is updated in asynchronous layers, only 1 of which is the OS version.
Another of the asynchronous layer updates is the "Google Play system update".

To wit...
(important given Samsungs account for more than half of Google Play revenue),

*Some Samsung phones haven't been getting Google Play system updates for months*

"First things first, what is a Google Play system update?
Distributed outside of major Android updates, a Google Play system update
handles certain system features, often tied back to Google products.
For instance, the latest Google Play system update includes changes
to the Play Store, support for QR code scanning in Wallet, and more.
Often, these updates can even bring bigger improvements.
In October, for example, Google delivered support for pairing Wear OS
to multiple Android phones, disabled Nearby Share in work profiles,
and more."

"As reported by GalaxyClub, some Samsung Galaxy phones have been sitting
on the same Google Play system updates for several months or even
longer. The issue seems to be encompassing many different Galaxy
devices across different versions of Android."

"It was found that the Galaxy Z Fold 5 and Galaxy S23 Ultra were both
stuck on the July 2023 update, while Galaxy S22 and Galaxy S21
were on the October update. Meanwhile, Galaxy A52 was on the
September update, while Galaxy A34 was stuck on the August update.
In all cases, checking for updates was either met with a message
saying that "your device is up to date" or that
"updates are temporarily unavailable."

The exact cause of this is unclear, but it's apparently not the
first time this has happened. It was noted early this year that
the exact same thing happened, with a variety of Galaxy devices
struck on older updates.

For affected users, there's nothing to be done, as Google Play system
updates can't be manually installed or sideloaded. That said,
since it was fixed once before, it can presumably be fixed again."
