It's not "on Android", it's whichever keyboard came with your phone. On iOS extremely small number of people use non-standard keyboard(it was later allowed), but on Android the keyboard was always an app and there are many.
The Google keyboard on a Google phone for some locales can be very different. Notably, the keyboard for Japanese doesn't do the spacebar thing, on the other hand, it contains actual keys to move left and right.
