When a phone gets upgraded to a new version of Android, there are a lot of noticeable changes and most of them are positive. Some are more subtle, however, and often just go unnoticed. Samsung introduced one of those subtleties with their version of Android 8.0 Oreo as screenshots are now being identified based on where they were taken.
A screenshot of the home screen or app drawer will now have the file name, Screenshot_Samsung Experience Home. A YouTube screenshot will be Screenshot_YouTube and so on.
The current date and time will still be there, just as before. Only the names are changing to be more specific. This is again subtle and most users either won’t notice or care, but if you take a lot of screenshots for work, etc., it could come in handy. Samsung is making this change itself with the Oreo update and it’s not an official change from Google.
Screenshots are stored in both the Gallery and Google Photos, and can also be accessed from the My Files app (or third-party file manager) – DCIM » Screenshots folder.
