Unlike GA, Samsung tells you upfront its a 3rd party app. It can do some things, macros, that GA can't. GA, using a more developed language recognition, is helped by thousands of app developers.
It will get better much quicker with the new ai development. In the meantime, you get a included shortcut hardware button. I use it to bring up my phone dialer. If you don't want to use it, just don't. I doubt any of us use all of the functionality of the mini computer we say is a phone anyway. Heck, Apple won't even put a back button on anything, so annoying looking for the 'back' word or an x, and you complain because it's not up to HAL standards yet. What's all the emotion about an optional to use button. It's not like it's blocking the screen or something, iykwim.
