Hopmedic-
I'm using an 8x and I had unnecessary problems with Verizon's Backup Assistant Plus. My problem was not seeing any changes when I try to edit my contacts even though phone allowed me to go through the steps of editing. Exhausted pretty much every option from un syncing any email accounts with Tech support from Verizon, Logging onto my Verizon wireless account and removing or editing my contacts, and even restoring to default factory settings. Nothing helped so I decided to just use my outlook for contacts and removed / deactivated "Backup Assistant Plus."
For the 8x:
1. go to settings and at the very top swipe left to view "applications"
2. Scroll down until you see "people" and go into that.
3. Once In "People," scroll down to the very bottom where you will see "accounts."
Below, you should be able to see all your email accounts that you have added to your phone.
4. In that section you should be able to see "Backup Assistant Plus," hold onto "Backup Assistant Plus" and you should be able to see the option to delete / remove.
5. Once you accept you should get one more confirmation telling you something about deleting will remove all of your contacts blah blah blah.
That should do it. Hope this helps. I was able to remove BAP without receiving any updates for it.
If you want to use it again, just go to settings/system/, scroll all the way to the bottom and you'll see BAP"activate your free Verizon service"
