Touchmove / scroll or something problem

Hi everyone,

I try to learn ionic framework. I have some problem. Maybe you can help me. I’m learning how to code newer. I checked many people’s code. They didn’t do anything special for touchscreen or I couldn’t understand…

My problem is that I can move screen down/up with touch.

If you help me I’m so happy.

Thanks for helping.

Are you testing this in Browser or in Device

I’m testing both of them
