Hello there, junclejeffllc. I know an option to modify your screen display so you can utilize your keyboard and work with your sales transaction in QuickBooks Online.
With a tablet as big as the Samsung Galaxy S8, you may want to rotate the screen using the Auto-Rotate screen option. Thus, whenever you move it vertically and horizontally, it will automatically adjust.
To enable it, go to your Settings app or scroll down until you reach the Home Screen, then choose Rotate to landscape mode. Tap to turn it on. Alternatively, you can easily find this feature from your home screen. You'll have to scroll it down to see it.
If you use the QuickBooks mobile app but it doesn't affect the display upon enabling it, you can use any supported, up-to-date browser.
For future reference, you can read through these resources to personalize and add specific information to your sales forms and then account for your customer's payments moving forward:
