If real keyboards on a phone were such a good idea, why does nobody still make them and why does everyone that tries get 0 sales.

If you enjoy this stuff, or if there is an accessibility angle, then go with my blessing. Otherwise the touchscreen keyboard is better for most people. If you must type on a real keyboard use a full sized Bluetooth keyboard, which will be better in every way.

interesting, but more practical to just get a bluetooth or usb-c full-size keyboard. And those will work with any computer and be easier to use.
