Google’s new test on the security of smartphones powered by the Android operating system has raised questions about the software’s data encryption capabilities. A group of German researchers recently reported that the secret contents of the set were leaked when the Android device was cooled in the fridge. Possible Maybe.

Google launches data scrambling system for the first time on Android with the Ice Cream Sandwich version. While the feature works well to protect the personal information of ordinary users, it can be a “nightmare” for law enforcement and forensic personnel.

M মller, Michael and Flex, researchers at Frederick Alexander University, first put a Samsung Galaxy Nexus handset in the fridge and cooled it to a temperature of -10 (minus 10) degrees. They then noticed that the device became very unusual when the set’s battery was quickly connected and disconnected, and then a custom-built operating system could be installed on it. The three researchers used their own custom code, “Frost (Forensic Recovery of Scrambled Telephones)”.

Data retrieved by Frost software can be copied to a computer and analyzed. In this way, researchers have been able to hack the Android phone’s contacts list, browsing history and photos.

Although the Samsung Galaxy Nexus was used to test the performance of Android’s disk operating system, the researchers said that other Android devices may have similar flaws. The same error has been observed in desktops and laptops before. Mr Mueller claims they are the first to conduct such research on a phone.
