The page shrinks when clicking on the textbox

In my project, I have added a plugin that is a textbox, after I convert it into an apk file, and when I run it on an Android device, by clicking on the textbox the page size decreases, help me overcome this ???

I made a project, where I added the textbox plugin, where when I clicked on the textbox, the page display on the PC looks fine. but after being exported it becomes an apk and I run it on android the page display shrinks when clicking on the textbox and if I release it from the textbox then it will return to normal or zoom again. please help me solve this problem .. ????

Two ways to deal with this:

1) Change full-screen scaling mode to Scale Outer or Off. You may need to re-design some things in your project for this..

2) Don't use TextBox control, create your own text box and keyboard:
