I really miss Palm's zen. Great sweet spot of discoverability with a clutter-free design that didn't sacrifice functionality. I could even make the buttons do useful things instead of just opening a Bixby TOS I've declined a dozen times.
I use an app called bxAxtions, and I'm pretty sure I didn't need to set up Bixby at all or agree to any terms of service (I can't remember for sure). I had to run some ADB commands to grant it extra permissions, and I think Bixby doesn't run at all.
