[Fire HD 8 and HD 10 General] mistermojorizin:
I tried that method. It didn't work. I've tried to research it and it seems the lock screen is really backed into the rom pretty deep. I've read someone mentioned they got an app that keeps your device unlocked and that's how they get around it, but i didn't want to run another app.

I had them disabled this way before root, but too many of the amazon functions didn't work. I like alexa, and prime video and appstore, for example. Also, you can uninstall the amazon launcher. That was the first thing I did when I got root (I had *no* launcher at all for a little while, and it was pretty funny, I couldn't figure out what was going on for a minute, but easy enough to solve - install nova).

also, someone asked about making "ok google" work.....I don't recall if it worked, but I know that once I disabled the above listed apps, google became my default assistant, and would ope with the longpress of home button. I *think* the main one that needs to be uinstalled is alexa for that.

I got live wallpapers to work by installing a livewallpaper picker as a system app, then updating it through apk mirror (wouldn't work until I did that). I messed with trying to get gmail or inbox to work, but gave up on that and installed 9 mail (i had bought it back when my organization was using outlook, but now we use gmail for business).
