Google Nexus phones are vulnerable to malfunction due to repeated SMS attacks. This flaw in the devices has become an issue that Google is looking to fix for the sake of its valued clientele.
A hacker or anyone wanting to disrupt the normal working order of a Google Nexus phone just has to send a large number of special text messages. Hacker can reboot or disrupt the mobile's Internet connectivity via SMS attacks. The problem first came to the attention of Bogdan Alecu, a system administrator at Dutch IT Services Company Levi9. He noticed that Nexus phones are vulnerable to denial-of-service attack via SMS. On Friday, he is presenting this vulnerability at the DefCamp security conference in Bucharest, Romania.

The piling up of one special SMS upon another causes a dimming effect to take place on the Google Nexus phone. And there is no audio signal to let you know that this treacherous act of sabotage is taking place under your nose. Unless the owner looks at his phone he won’t know about it. The moment the number of text messages exceeds the 30 unit limit, the phone starts acting up.
For one thing it reboots. It will stop receiving any calls or text messages. Even notifications will not be entertained by the device. Or it might lose its link to the mobile network. What that means is that the Internet connection is severed. You will have to start all over again. At other times, the messaging app goes haywire.
Alecu has been noticing such a malfunctioning in the Nexus phone since a year or so. The strange behavior has been seen on the Galaxy Nexus, Nexus 4 and Nexus 5. They include those running Android 4x versions and also the latest Android 4.4 or KitKat versions too.
