I used this plugin to send message to android, so far so good, thanks. But I found one issue, don't know if this is intended. If my device is on, which means, the screen is on, or just off, message can be received in the phone, no problem, but if my phone is in inactive status for couple minutes, message can no longer be delivered. I googled a lot, someone said it is because GCM is using TCP port xxx, and if the phone is inactive, network will be disconnected. Time varies based on different network provider. have you guys experienced this senario? If so, this might be a biggest issue for GCM. But my iPhone has no issue at all, it can instantly receive message no matter if user is active or not. Thanks

This is a client-side issue, that you need to resolve in the receiving app. You used to have to use a WakefulBroadcastReceiver, but I think this has recently changed with Android M.
