Hi webteamkingdom,
can you please provide more details of the issues you are facing? Our Free Themes work fine on mobile (specially the flat one) but our Club Themes provide a much better user experience in mobile. We even provide a Mobiel theme to our Silver and Gold Members:

I am using "flat" theme, but it does not work well in smartphone view... http://dsklv3.digiweaver.com/index.php/de/component/jevents/monthcalendar/2017/4/-?Itemid=1

Any clue? I want to remain the existing design, if I change the calendar to "Smartphone" theme, I have to work out all the design again including the module which display the event list, which I want to avoid doing so.

Regards,

As another has pointed out, the Flat theme is not mobile responsive, not is the ext theme, geraint, or anything in the JEvents package.

I think Flatplus Theme is your best option. You may take a look on how it works on our demo site:

http://www.jeventsdemo.net/all-events

You may actually change the theme on that page (check the module on the right) to test our other themes.

Best!
