Can Siri be disabled within an app?

I'm working an on iOS game and recently tested on an iPhone 4S. Siri activates sometimes when my thumb covers the proximity sensor. This is a feature of the 4S. Instead of holding the home button, users can put the phone to their ear to activate Siri. But in my game the activation is not intended and it interrupts gameplay.

Can Siri be disabled within an app? Is this an iPhone 4S bug?

How do I restrict Siri on iPhone?

To restrict Siri features: Go to Settings and tap Screen Time. Tap Content & Privacy Restrictions, then tap Content Restrictions. Scroll down to Siri, then choose your settings.

Is Siri listening to me all the time?

No. Apple says that Siri is not eavesdropping at all. Instead, the software's ability to respond to a voice command is programmed in. So, it's not really listening at all times.

Setting :

[UIDevice currentDevice].proximityMonitoringEnabled = YES;

Disables Siri from activating when you activate the proximity sensor. As a result although, it blacks out the screen when the proximity sensor is activated instead.
