Interface difficult to use on small screens (you can hardly see the current operation)

[jumase]

Steps to reproduce

On a 540×940 px screen, the display is too small to read numbers, as you can see in the screenshot.
Possible workaroud: horizontal view. But, this way, trigonometric functions names can't fit with that big font. Could it be smaller?

Expected behavior

Vertical view should have enough room to read current operation and result.
Horizontal view may display functions in smaller font size to fit inside the button.

Actual behavior

User can hardly see what's being written.

Calc You version

1.2

Android version

Android 10

Other details

Device: Motorola E2
To compare, I attach a screenshot of android calculator. As you can notice, the main numeric keyboard is as big as CalcYou numeric keyboard. I don't know if this is useful, but it seems not to be a coincidence, is it?
