If you’re wondering, “Where do screenshots go?”, you can easily view them using Samsung’s Gallery app. Open it, go to Albums, and tap Screenshots.
Now you see a gallery with all the screenshots taken on your Samsung phone or tablet.
Alternatively, you can use the Photos app that’s made by Google and found on all Android devices, including Samsung’s. Open Google Photos, and the screenshots are displayed alongside your Photos in descending chronological order.
If you can’t see them in the Photos section, tap Library and then Screenshots to view them.
