CommCenter watchdog timeout on iPhone: causes

A CommCenter watchdog timeout means the CommCenter system process did not respond within the allowed time, so the watchdog forced the iPhone to restart and wrote a Panic-Full log. It falls under Baseband / Cellular, with Medium severity. Not every hang is a hardware fault: read the other lines in the log to tell a software problem from a failing part. Scan the log with the Panic Scan app to get a verdict for your phone.
