[Fire HD 8 and HD 10 General] DragonFire1024:
These are the Amazon Items, for the moment, I left 'installed'. This may or may not have the same effect you would like so please be aware: you're choosing to make these modifications and I'm not responsible if you don't get the same results. If this list differs from what you 'uninstalled' or left 'installed', you'll have to factory reset in order to maintain the same list.

With that having been said, this list may or may not allow you to do several things: Install and use Netflix on the device (I've not done any work on my screen mirroring project in some time so I don't know if that will work), use Gmail without crashing, install and use VLC Medis Player to watch pretty much any video you place on the device (I just got caught up with 'Game of Thrones' and am now on 'Fear The Walking Dead').

Note: Gmail is give or take if it will work. With the list I am providing, Gmail works perfectly on this device. It's inability to operate may be due to one of the Amazon apps purposely force closing Gmail. Which app? I've no idea. The other Apps I listed above may already work without the modifications. I installed them after I settled with the current list below.

use App Inspector to get package names.

This is what I left installed thus far:

- Accessory Notifier

- Amazon Bluetooth Internals (Note: I had previously uninstalled this on other occasions and I didn't notice any change in Bluetooth operations, though I just use it for music streaming).

- Amazon Backup and Restore Internal SDK (I also had this uninstalled previously, but I honestly don't know if it has any effect on backing up or restoring).

- Amazon Bluetooth DFU (I don't recall ever uninstalling this)

- Amazon Device Middleware Debugging Tool (No idea what it's used for. Only uninstalled it once).

- Amazon Device Settings (I believe uninstalled this a few times before, though not 100% sure).

- Amazon Device Settings Internal SDK

- Amazon Facebook Share (Uninstalling these removes Facebook, Goodreads etc from the list that allows you to share to an app).

- Amazon Metrics Service Application (Function unknown)

- Amazon Platform (I've seen this hidden and or disabled in previous OS versions while reading older threads. I've never uninstalled it though. Effect of doing so is unknown, if any).

- Amazon Recess (Uninstalled previously and didn't notice any effects. Function unknown).

- Amazon Whispersync SDK

- AmazonKKWebViewLib (See Amazon WebView)

- Backup and Restore (I am pretty sure you need this to backup data using Google's Servers).
