What should I do if Huawei nova3 shear board is not easy to use?

How to open the mobile phone clipboard:

Method 1: Open the SMS and enter the editing page. Press the phone screen in the blank area of the SMS editing area (in the box of "Enter information"), and the "Paste" and "Clipboard" menus will appear. (The clipboard cannot be empty at this time, otherwise it will not appear. )

Method 2: Open the mobile phone browser. In the blank space of the search bar (or other input box where text can be entered), pressing the phone screen will also pop up the "Paste" and "Clipboard" menus. (The clipboard cannot be empty at this time, otherwise it will not appear. )

Method 3: Open the mobile phone browser. Press and hold the phone screen in the blank space of the search bar (or other input box where text can be entered), and the "Clipboard" and "Long Text" buttons will appear above the input method keyboard (in this case, whether the clipboard is blank or not does not affect).

PS: If the above method doesn't work in one input box, please try it in different input boxes on different pages, and it will usually succeed.
