Often when my screen is off, I won't get notifications for messages, IMs, emails on my phone. As soon as I turn my screen back on, they all come through at once. This completely breaks any sort of "push" functionality and makes the phone useless for real time messaging.
Connection type makes no difference (WiFi or Data).
Keep WiFi on during sleep is set to Always.
WiFi optimisation is set to OFF (turning it on makes no difference)
Anyone facing similar issues? There were some related threads on XDA about WiFi driver bugs but none that applied to Mobile data as well. For me the phone just sort of actually sleeps when screen is off.
