Look, this is a comnon issue.

But, the real nitty gritty of it you may not want to hear.
Even so, it is what it is, and there is no way to change that.

The bloatware that you have is put there by your carrier and/or device manufacturer.

Depending upon the device, the carrier, the manufacturer, and whatever deals that the bloatware devs may have reached, the apps may or may not be able to be disabled, uninstalled, either, or neither.

But here is the thing- even if you could uninstall them all, none of that space would be available for your useage anyway.

That is just how it works.

Yes, it is sometimes possible to root the device, and then you may be able to use some of that space- but devices nowadays are very often found to be not rootable anymore.

The device needs to be popular, and desireable enough for developers to want to invest the effort to find exploits in the operating system- and these exploits need to exist in the first place.

As far as what is realistic and simple, uninstall whatever bloat you can.
Disable what you cannot uninstall.
The rest is going to stay there.

When you do things that require more RAM, the OS will turn off apps that are not needed or that have not been used lately in order to make room.

It does this on its own, with no direct input from you.

There is a method to keep bloatware from being active at all, but it requires connecting to a computer and changing some commands.
There are videos on Youtube describing this.

The apps remain on the device, but command changes prevent them from starting at boot and from appearing in your app drawer.

An app that may help you is called Greenify.

I use it myself.

It can automatically forcestop apps when the screen turns off.

A paid version allows the forcestopping of system apps as well.
But, you will find that the majority will soon restart.

There is a FOSS app that does the same thing for free, but it is not as simple to set it up and use, called SuperFreezZ.

Personally, I use Greenify, the paid version.
I uninstalled and disabled whatever crap I could, let Greenify control the rest, and moved on with my life.

There really is much fun to be had with Android once you get over the bloatware hangup.
Like I said, that space will never be available for your use- even if it was empty.
I wish it were different, but it is not, and that is just the way it is unless you can root the device.
And rooting opens up a whole new can of worms.

So here are the apps I mentioned.

Download both of them, and try them both one at a time.

I think you will find as I have that Greenify is the best choice.
