Researchers in Sweden and the UK have revealed that anyone will be able to steal the unlocking pattern of your Android phone by switching your device to an improvised Sonar system. Using the speakers and microphones in the phone, where the sonar will be able to capture finger movements in the screen and identify the possible patterns that can open the phone.
This technique is called SonarSnoop and exploits the attacker first to install malware on the victim's phone. This malicious code transfers the sound waves from the speakers on the phone, and will pick up the waves again from the microphone mode fingers to locate them. The method will detect the lock pattern used to close the phone.
This new technology was successfully tested on Samsung Galaxy S4. For protection, as now, you should not rely on the patterns of locking your phone and protecting it. Most phones are now supported by fingerprint sensors, which are safer than unlocking. If you're using an old phone, we recommend placing a strong passcode instead of the unlock pattern, even if the latter is more convenient for you. You can also set up your phone to clear all data after a number of unsuccessful screen lock attempts.
