Wi-Fi won't stay off I have a Motorola Droid and have just installed the latest update. 

The Wi-Fi network at my workplace is temperamental, so I prefer to simply turn off the Wi-Fi and use 4G. 

The issue is, when I turn it off (in Settings ~> Wi-Fi ~> move the slide bar to "off") it shows as off, however the next time I turn the screen on, the Wi-Fi is back on. 

How can I stop this?
This is strange behavior, and one I have not actually seen before.

Do you by any chance have an app installed that could be turning the Wi-Fi on? Also, how long do you wait between sliding the slider and turning the screen off - it may not have had time to update.

I have only ever since this issue once, and I believe that it was a software issue.

If you cannot fix it, I would recommend 'forgetting' your works Wi-Fi network, so that Android does not automatically connect to it. You can do this by long pressing on the Wi-Fi network in the Wi-Fi settings menu.
