I hava a BLE device which can be found by andrioid 4.4 and 6.0 smartphone, but cannot be found by apple iphone5s iOS 9.3, what could be possible wrong with it?

I am not sure about the iPhone 5S but, Apple broke the BLE functionality in iOS9 for the iPhone 4S and don't seem to be interested in fixing it.

I went to an Apple store with my iPhone 4S to complain and they said the only options were for them to replace my phone with an iPhone 6 (I would have to pay for this) Or I could swap my phone for an older iPhone 4S which still had iOS 8 on it. (but the phone would be used and possibly scratched etc)

So basically my iPhone 4S is no longer usable for BLE testing ;-(
