How to Delete Empty Rows on Google Sheets on Android

Steps

Open Google Sheets on your Android. The Sheets app looks like a green document icon on your Apps menu. It will open up to a list of all your saved spreadsheet files.
Tap the file you want to edit. This will open the spreadsheet in full-screen.
Tap and hold a row number. Find the empty row you want to delete, and long-press the row number on the left-hand side of your spreadsheet. This will highlight the entire row, and open a pop-up toolbar above it.
Tap the three dots icon on the toolbar. A new menu will pop-up.
Select Delete on the menu. This will delete the entire row from your spreadsheet.
