I updated my phone to 4.3 this morning, and the Device Management notification came up and I cannot make it disappear. Anyone else have this problem?
Q: Does this method factory reset your phone?Had the same issue with "Device Management is running" notification in the status bar for over an hour. Restart option from Power button selection didn't work. Finally did a hard restart (Press the down volume and power buttons at the same time for a few seconds until a message pops up saying your phone will restart - It's like pulling out the battery on other phones) and when the HTC One restarted, after a few moments I got the "Upgrade Successful to Android 4.3" message and the "Device Management is running" notice is gone.
Hope this works for you.

Not listed in mine.Another thought is disable it, unless your using it. Its listed in apps..
