I don't know what will happen on your 5S, but on the XR if you rotate the phone to landscape position you will at least get a wider, larger keyboard. It does not occupy the entire screen, but it is more keyboard.
On a Mac since 1984. Currently: 24" M1 iMac, M2 Pro Mac mini with 27" BenQ monitor, M2 Macbook Air, MacOS 14.x; iPhones, iPods (yes, still) and iPads.
