That's unfortunately a huge security risk just to fix a stupid keyboard flaw

No...

I see lots of people posting that this 5s key truck worked for them, but it's always for a different tablet, the FE, the s8, etc., than what the thread is supposed to be about. I don't think I've seen a single post that showed this works with the s7+...

Did the 5s key thing work for you?

5s thing totally didn't work for me. I have a S7+ with three keyboard. Wonder if there's something wrong with this keyboard.
