Android 8.0 Oreo-based Samsung Experience 9.0 changes its previously employed screenshot naming scheme by including the names of the apps shown in one's screengrabs, thus making them more informative in the context of file lists with tiny or non-existent thumbnails which couldn't help you recognize individual images. Whereas the previous versions of Samsung's mobile software would primarily name screenshots based on their capture date and offer little instantly identifiable information in such monikers.
The screenshots taken on the Galaxy S8 and Galaxy S8 Plus running the fourth preview version of Samsung's take on Android 8.0 Oreo all have names that start with "Screenshot_" and continue with the actual name of the app that's depicted in any given image, as seen below. Screengrabs of one's home screen or app dock will simply insert the name of the launcher that's one display, with the default option being Samsung Experience Home. It's presently unclear how the software handles multi-window mode screenshots, i.e. whether it includes names of all apps shown in an image or just the last one that recorded user input. The latest beta build of Samsung Experience 9.0 became available to a limited number of testers in Germany, France, Poland, and Spain just yesterday and should soon roll out in China and India. Besides changing the screenshotting mechanics of the operating system, the new firmware also introduces a broad range of bug fixes and performance improvements and is generally presented as a near-final variant of Android 8.0 Oreo for Samsung-made handsets. The software is presently scheduled for an early 2018 release and will most likely start rolling out in late January, though minor delays aren't out of the question as Samsung has yet to thoroughly test every aspect of the OS and verify no severe bugs are present in its code. The latest experimental version of Oreo-based Samsung Experience also disables the DeX functionality on third-party docks as the Korean tech giant is now seemingly taking more proactive steps to prevent manufacturers from profiting on cheap alternatives to its DeX station.
While the newer iterations of MIUI already support a similar screenshotting functionality, stock Android doesn't, with the newly uncovered feature being yet another example of Samsung's efforts to improve on every iteration of Google's operating system. While the firm's proprietary software builds generally aren't as smooth as their native Android peers, the debut of Samsung Experience 8.5 already introduced a wide variety of improvements and significantly enhanced the overall performance of Samsung's flagship devices.
