I have checked the forms in your account and I can see they load responsively in an Samsung Galaxy s6 device, I have also tested the form in other devices with Android 6 and I can see the forms load fine.

Have you embedded your forms in a website?
May be that this happens when you embed them, please do note that the style applied to the webpage where the form is embedded may also affect how it looks in a mobile device.
Please share us the link to your webpage so we can further check how the forms look in mobile devices, we will be glad to help.
