Companies that create tools for “rooting” Android phones may be within the law, but they may be inadvertently paving the way for malware developers. This allows users to get rid of pre-installed apps that are otherwise impossible to remove, to personalize their phones beyond what is allowed by the official limits, to get better backups, or better power management tools. “It’s actually a legitimate business to distribute these exploits. It can be used to do good things,” said Qian. “In practice, however, it means that users are, in effect, hacking into their own phones,” he said.”]
