The most insane thing which I wouldn't believe if I hadn't experienced it myself, but Samsung will periodically just install random apps and games on your phone. You delete them, then a month later, new apps show up. It's one of the most aggressive anti-consumer thing I've seen and it's coming from such a large player.

I'd guess it's happening during silent updates to your android OS. Those can come packaged with anything Samsung wants. I had a similar fight lately with HP's printer software which insists on waking your computer up for a printer health check and reenables the scheduled task randomly even without updates. Finally excised it from my PC.
