Notification content is not showing after latest software update

[Novgorod]

Since the latest June 2025 update a few days ago, my S22 Ultra is not showing the content of notifications anymore, just the app name. It's supposed to show e.g. a portion of the message content in a messenger app notification, but it's disabled or hidden:

As you can see, this is the normal notification drawer in the unlocked state, not on the lock screen (I have notification content enabled on the lock screen anyway). It happens for all apps (Signal is just an example) and a reboot didn't change anything. All notifications are shown in the notification history with the content, so the content is being correctly recorded, just not displayed in the popup. It worked correctly just before the recent ...7FYF1 update, which was already One UI 7. Any idea how to fix that?

Try this I found on my S23u.
Go to SETTINGS - NOTIFICATIONS - Notification pop-up style
And then chose detailed.

This didn't help. After setting it to "detailed", I get no notification popups at all, only the notification symbol appears on the top bar next to the clock. There's also still no content shown in the notification drawer (exactly the same as in the initial screenshot).

Ok, it was caused by new Google "privacy" horseshit in Android 15, which was disabled by default but now it has been silently enabled in the most recent Samsung update. Now the content of notifications is hidden by default during screen sharing (e.g. using a remote control app like Rustdesk to remote into your phone) for "privacy" - nevermind that you can just tap on the notification to read the message in the app if you're remote controlling the phone anyway, whatever... To disable this farce, check the option "turn off screen share protections" in the developer options and everything will be back to normal.
