I thought it was strange, so I turned wifi back off and the same thing happened. I rebooted, tried again, and got the same result. I was trying to think of a way to see what was happening, so I tried using the Screen Record function in Gravity Box, which didn't help much, because it happens so fast, and no info is displayed, just a black window that goes away quickly.
I then turned on the CPU usage in Developer Options to see if anything consistently came to the top when toggling. I saw a few apps each time Plume (Twitter), and Maildroid (email) were two of them. Both of these apps behave differently on wifi and 3G/4G (push vs. pull), so thought -maybe- it could be something with that. I uninstalled both of those, rebooted and tried again, getting the same result.
I recorded the screen when this was happening with the CPU usage displayed, and was wondering if anyone has any ideas? I don't really want to uninstall and reinstall EVERY app on my phone, so I was hoping someone may have seen this before or see something I'm missing when watching it happen.
Thanks for any input anyone can offer!
