20200128 Screenshot capture is generally a function of the operating system, and so does not require an additional application. A common approach is to press and hold down the VolumeDown and Power buttons simultaneously. On some versions holding the Power button down includes Screenshot as one of the options. On the Samsung Galaxy S7 and earlier models, press and hold the Home and the Power buttons simultaneously until a screenshot is taken.
The screen image is often saved into a Screenshots folder
under Pictures on the internal storage. This can be auto
uploaded to the cloud (e.g., through Nextcloud).
