A cyber security firm is warning Android device users of the largest smartphone flaw ever discovered.
95 percent of Android smartphones can be hacked with one, simple message, according to technology experts.
Malicious code can take over the device and allow hackers to have access to personal information.
950K Android devices made in the last five years may be affected.
No devices have been hacked at this point.
"Google already has a patch for this. The carrier has to deploy it. You don't have to do anything but in some cases you have to initiate the security upgrade. By the way, you should always do the security upgrade,' said Palmer.
