“Be patient” is what Google is asking for. Google is working on issues for the Galaxy Nexus after the last major update. There have been minor issues pertaining to the handset’s volume control adjusting on its own as well as the device’s touchscreen not responding properly. There was also a 4G signal issue with strength and availability after the Verizon LTE version hit.
Now we hear of users experiencing random device resets. Lots of users have sent devices back hoping to receive a non-defective device, but soon find out the same issues are plaguing both HSPA+ and LTE versions. It’s unclear how, why, or even when these anomalies are occurring. Others find peace of mind when changing their system hardware.
Wait for Google to find a fix or change your hardware? That’s up to you.
