One of the amazing features in iPhone 4S is the intelligent voice assistant Siri. It lets you send messages, make calls, set reminders, locate places and many more awesome features, yet not without a major flaw.
Some iPhone 4S users have complained that Siri can still be activated to make calls, send messages or set reminders even with the passcode enabled which renders the whole passcode “protection†process ineffective.
No worries folks, it has an easy fix. Go to your settings > GeneralAllow Access to Siri > off.
