LG G8 II Tablet with Android OS

[Android Central Question]

LG G8 II Tablet with Android OS and the question is how in the world can we allow from an Android perspective remote control attacks from Cellular data? (Not WiFi or Bluetooth) I thought that Android would be far more advanced by now with this but I’ve seen it today. Even after doing a factory reset the hacker had control even before I could put password into WiFi. It was no APP, no flaw of mine etc they had direct control over the tablet over only a 4G connection via cellular carrier. Disappointing Android...
