Links going crazy

I am trying to add a link on my WordPress site but every time I click the button the link editor pops up and calls the keyboard on my android device up. The keyboard then hides itself. Then reappears. And this goes on in a loop. I can’t add any links. It just goes crazy.

I only have this device to edit my site so I need the solution to be in specific for editing on an android device. My apologies.

Thanks
