Thanks so much to all who replied to my question with advice. For future reference though, I have one more question; what does device administrator mode do, and what is it actually intended for? I was unaware the app was, itself an 'administrator' and misunderstood the meaning when I initially saw the word in relation to the app. In all honesty I thought it meant a mode I had accidentally set my device as a whole into, or something along those lines.
Excellent! Glad it helped! Device Administrator is a permission that gives an app special privileges to perform some actions. In some cases, like with 'Find my device', gives you remote access to your phone (add a password or wipe the device if stolen). In other cases, like with custom launchers or toggles apps, it gives permission to add shortcuts to lock the phone.
I'm not sure what's the case with that 'Update Service' app but I guess it's part of Verizon bloatware. Let it unchecked as Device administrator for now and see if you get a prompt to enable that permission again.
