What this com.qualcomm.qcrilmsgtunnel does. I stopped it service and process nothing really happened. I restarted the phone and it is back running. Anybody know what this app does. My phone is Nexus 5, 4.4.3.
Its the stock phone dialer app.
If you have enabled 'Fast Dormancy' on a device it may cause a spike in activity / battery use for this process, it appears to be a confilict with this option.
