Lockscreen Security Vulnerabilities

iOS 7 Lockscreen has been under scrutiny for its security loopholes and vulnerabilities. Apple recently rolled out an iOS 7.0.2 bug-fix for Lockscreen passcode glitch that allowed unauthorised access to Phone services. However, another bug was unearthed a few days ago that lets anyone bypass the lockscreen passcode and gain access to the Phone app.

Fix: To disable Siri from Lockscreen, go to Settings > General > Passcode Lock. Scroll down to Allow Access When Locked section and choose Disable Siri option.

Miscalibrated Motion Sensors

iPhone 5s is reportedly affected by a miscalibrated motion sensor glitch that results in erroneous motion-related data being sent to apps. It is still unclear if this issue is hardware or software-related that could be fixed via a simple update.
