Phonegap version 4.2.0-0.24.2
Emulators (empty library):
iPhone Retina (4-inch), iOS 6.1: immediate response
iPhone Retina (4-inch), iOS 7.1: immediate response
iPhone Retina (4-inch 64-bit), iOS 7.1: immediate response
iPad, iOS 7.1: approx. 6s before response
iPad Retina, iOS 6.1: approx. 6s before response
iPad Retina, iOS 7.1: approx. 6s before response
iPad Retina (64bit), iOS 7.1: approx. 6s before response
Devices (filled library):
iPhone 6, iOS 8.4: immediate response
iPad Air, iOS 8.4: approx. 25s before response
So it seems to occur on iPad only. Android devices are working as expected. I'm working with Xcode 5.1.1 on Mountain Lion, I don't know if that's of any influence.
I hope someone can shed some light on this.
Kind regards,
Bernard
