[Q] Weird Post-root behavior
So, I recently rooted my Verizon GS4 running VRUAMDK Everything was going as expected for a while, life was good, all of my root apps worked perfectly. Also, the boot logo was what I expected: the samsung logo, with the unlock icon and the word custom to signify that I had flashed custom firmware. Over the past few days, I have been in rural areas with extremely spotty and intermittent data, cell, and wifi coverage. I was walking out of a building, where I think I had cell coverage and wifi. I got a text from 910-090-009000, which included some random foreign characters that I can only assume should have been binary data followed by "com.vzwdmserver".
After this, my phone's cell signal indicator showed bars, and appeared to have a symbol over it that was not in the icon glossary, it may have been a house, I don't recall exactly. I then rebooted. When I rebooted, all of my apps were gone from the drawer and the home screen, it showed
"safe mode" in the bottom left, and I got force close messages from a couple of apps. I then rebooted again, and everything was mostly back to normal except that all of my accounts were logged out, accessibility for the app LightFlow had been turned off, and the "custom" boot logo had been replaced with the stock one again.
Moral of the story is that I haven't a clue what any of this means, or whether I should be concerned about it. Anybody else experienced this, or know why it might have happened?
