I cant turn off my voice control
i dont know how to turn off the voice control
第四代iPhone。维修过程直观易懂，但前置玻璃和LCD面板无法分开，只能作为同一零件更换。GSM版本， 8, 16, or 32 GB 容量 / 型号 A1332 / 黑色或白色
Also applicable to iPhone 4C (iPhone 4 CDMA).
This setting seems to have been removed. Prior to 7.1 it was in:
Settings > General > Passcode > Voice Dial > OFF
Since 7.1 things have moved around a bit in settings, and the equivalent area would now be:
Settings > Passcode
… only the option is absent. Hopefully it will be returned, as my sticky home buttoned iPhone 4 is also occasionally dialling nonsense for me.
So, to summarise, there seems to be no way to turn it off for iOS 7.1 on a non jailbroken iPhone.
