The User-Agent string has been reduced in Chrome on Desktop and Chrome on Android platforms since Chrome 107. Beginning in Android 16, the default User-Agent string in Android WebView will be similarly reduced.
Updated User-Agent string
The default, reduced WebView User-Agent string will have the OS, CPU, and Build information reduced to the static "Linux; Android 10; K" string. Minor/build/patch version information is also reduced to "0.0.0". The rest of the default User-Agent remains unchanged (and is unchanging) as seen in the following diagram:
