I finally got my phone re-flashed and my Sprint security update and all Sprint stuff is gone. I was told even though I switched to Verizon with unlocked phone it still had some of Sprints network and my software said April but it was from the Sprint April 16th update which didn't fix LTE problems and we now have Verizon. We were still having problems. The Verizon tech said get a new sim card to be safe so I did. Hope this fixes LTE problem my husband's phone was worse he will get his re-flashed Saturday. Mine was intermittent and I want to go back to the one place I didn't have signal before tomorrow and see. But we have unlocked so I am not expecting to get the update yet but I will check. I know carriers get theirs 1st.
