Large Inbound Latency on Android

Hi,
I’m developing an audio conferencing app for android and iphone and the former has large inbound audio latency (350ms) as compared to the iphone (200ms). The latency seems to be worse on Samsung phones. A react based version of the app, running in chrome, works much better, keeping the latency to 200ms or less. Are there any known webrtc latency issues with androind and react-native?
Regards,
Maciej
