Mobile and Tablet screen – Arrows not working

Hi @guruk2k5,
We’re sorry for late response.
FYI, it’s default setting for mobile and tablet that users are just enable to use options for product quality. If you need to use arrows like your demand in small devices, you can use this jquery: https://www.jqueryscript.net/form/Customizable-Number-Input-Spinner-Plugin-with-jQuery-Spinner-js.html
