What does the green or yellow icon mean?

As you may have noticed, a small green icon next to the keyboard icon sometimes appears on the upper right margin, followed by a yellow round icon.

Both symbols display the update process of the KORONA POS software. That is, when you see the first green icon with the loading arrow, the POS has downloaded the latest version from the cloud.

To perform the update, press the yellow icon. The POS then reboots and executes the update.
