I'm now trying to record images at approximately 10Hz on a Samsung Galaxy SIII phone using the android SDK, but my program always suffers from large delays regularly. When I looked at the logcat, I found the following message associated with every time delay:

03-05 20:20:07.875: E/SMD(196): DCD ON

Could someone tell me what this message stand for? and how can I disable it?

  • could you please post the complete logs. I suspect some out of memory issue here, but not for sure. – Sdr Apr 17 '13 at 20:38

It seems the message E/SMD﹕ DCD ON is a part of inter process communication which is issued by SMD port due to DCD (data carrier detect), when the phone is searching for a mobile network to connect to. It only seems to happen on Qualcomm chipsets.

This message is probably not coming from your app.
