[Samsung Galaxy A3, A5, A7 (2017) Guides, News, & D] mindlery:
sm-a520w oreo rooted and cautious debloat

Here's my list. Obviously you will have to make up your own mind as to what you want. I am waiting for hades to be fully functional on my lame "w" variant.

I did twrp, magisk and INSTALLED IN RECOVERY the debloater downloaded from magisk. Still running pretty much everything I used to such as email, playstore and phone/messaging and a game.

Installed a terminal emulator to run the module... called... terminal emulator but was told to try termux. Get Termux if you prefer larger text. Not a power user by any means so both work great for me.

I don't think you will want to uninstall much more than 3 or 4 apps at once. I just knocked off families like the knox clan, facebook clowns but for google i knocked them off in pairs so they could watch themselves get eaten. My first successful root involved titanium and I just went nuts and was not rebooting and by about the 20th app my screen did some neat swirly effect and I think I saw the screen throw files at me. Then I got a message that root was removed. Oh well.

Don't be signed into anything that you're uninstalling might be important. If you're on the W variant you'll notice 2 programs not listed with FIDO in the name. Be careful because I got locked out deleting one or two of those and it probably was also a bad idea having a pin on the lockscreen because that was most likely what I damaged. Luckily I easily fixed it in twrp. Just do the obvious ones first if you are new.

You will see two Sim Services if you go to remove it but I only did one. I picked the first one and left the one underneath it. They will be numbered different on your screen unless you do it in the same order as me, which you won't. So, when I did it they were 66 and 67. I chose 66 and did a reboot. Yeah the other one is on the list in the terminal still, but I don't get the icon anymore anywhere so I was rather pleased and just left it like that for now. It is now seen as sim toolkit in your apps in system view. I don't want to even talk about it in case it hears me and puts an icon in the app drawer.

What did I notice? Phone is definitely a little bit quicker. By a little I mean you may not notice if you use animations. RAM is definitely happy with the weight loss and needs a new wardrobe. It sometimes boots up around 2 but will rest around 1.5 if idle. It never did that before and obviously this device is not being sold and used properly with all this crap on it and when you don't take these measures, well there ain't much room for more crap so might as well get an S9 and abuse that sucker until it runs worse than a device years younger. I will add more as I find out what exactly my plans are and more importantly after fully understanding what I am removing. If you want to follow someone's list that somehow has so much removed it doesn't make sense... it's because they have apps to use in place for what they want. If that is appealing just tell me what app you crashed and burned on and when you're sick of 7 or so fixings grab a custom ROM :)

Keep lock screen security off and sign out/detach yourself from apps as much as possible. You can delete the keyboard with a current working one but I put it back as the message app lost smiley faces :(

I use Virgin and deleted their useless crap. Some weird rogers stuff I knew was there but a little old for a recent update...?

Encrypted Sim? I hope not. Do Enterprise SIm/Vpn together and power off. Take out your SIM and power on. I just waited until it was done the 30-60 second warm up and put the SIM back in and carried on. If you don't do this you'll want to do it when the phone reboots and chokes and.... just take it out.

Some apps will downgrade and need to be uninstalled (like they should be) in your apps after reboot and others may linger in the debloater. Just do'em again.

Not the order I did but as it was exported and from 1 and 2 menu options

You can uninstall Dictionary NOT User Dictionary. Settings will not function at all. Instant fc. User Dictionary can be disabled though. I am sure it can be done but other apps not listed here like contacts most likely need to go with it.
