how to fix the screen position on Android 7.0 smartphones

[Android Central Question]

When playing sudoku on my CAT S41 (Android 7.0) the screen is allways moving around, depending on where I want to enter a digit.

This behaviour has started only these days, last week I could arrange the screen so that the entire game was visible

What can I do to stop this?

Welcome to Android Central! Is it only on that sudoku game? Are you saying that the screen seems to shift position, or that it's zooming in on its own?
