Why does the T-mobile app take up so much space?

Scroll until you find Device Manger or T-Mobile Device Manager (whatever it’s called) and select it

Select OK to Replace the App with the factory version

 

I have no idea what T-Mobile was tracking, but rolling back to an earlier Android version of the app cleared out all the user data and hasn't caused a problem since. Maybe T-Mobile was  taking snapshots or something to make restoring the phone easier. Whatever it was, it should have never been implemented this way.

So this worked, BUT THEN an "extra-hidden" system app called com.tmobile.pr.adapt did the same thing within 24 hours. And you can't "Uninstall Updates" - no such option exists. So it's just stuck taking up 99% of my phone storage, whether disabled, enabled, or force-stopped.

Also, for some reason, I had to use a third-party "service disabler" from the Play Store to find it again after disabling it the first time. Thought that might be important to note.
