system administrator Bogdan Alec from the Dutch IT-company Levi9 year ago exposed the vulnerability of the line smartphones Nexus, which he has since thoroughly tested. Devices Galaxy Nexus, Nexus 4 and 5 new Nexus can get reboot without desire for its owner or to deprive him of access to the Internet via a cellular connection.
These problems affected all models of Nexus on Android from version 4.0 to 4.4. In about twenty tested smartphones from other manufacturers such deviations were found. Alec repeatedly reported the problem to Google, and which promised to fix it in version 4.3, which was not done. As a result, he decided to talk about it publicly at the conference held in Bucharest DefCamp.
If send data to the so-called smartphones Flash SMS or Class 0 SMS with up to 30 pieces, it will lead to specific violations in their work. These SMS messages are distinguished by the fact that immediately appear on the screen, blocking of all other applications. At the same time they come completely silent, even if the machine is turned on in the settings of SMS notification sound. Therefore, the user is unable to immediately reject the arriving message.
Thus, the most likely outcome of such an influx of SMS is to reboot your smartphone. If you need to enter this PIN-code, the machine after downloading can not connect to the network. Another consequence could be “fall” of the “Messages”, although she immediately restored. Also, the unit can not restart, only to lose connection to the network, then it is restored – without the possibility of accessing the Internet. Next, you need to reboot your smartphone to restore full operation.
