InCallManager.start(ringback:"") make setInterval() to %50 speeder on real devices but not emulators (Emulators looks like not have a call manager).
Tested on Android 12 (MIUI 13) and Android 11 (LineageOS 18.1) Xioami devices.
When ı use react-native-background-timer not fix it but maybe some slower but causes crash WebRTC connection and some times console warnings new NativeEventEmitter() was called with a non null argument without the required removeListeners method.
