So randomly the button with the 3 lines. The pause button I think it is. Is not working.

When using the ps2 emulation, normally you would hold that button along with the right arrow and it would change screen size. Now all I have to do is press the arrow and the screen changes, making me think the pause button is stuck?

Is there a way of checking this? Because testing the buttons on settings, the pause button is not one of the buttons to test. I’ve also paid for a repair when I dropped it so in the past so would I have to pay again? Even though this time I haven’t dropped it. Please help i’m getting stressed
