Android 4.0.4 update causes network issues on Galaxy Nexus

Samsung Galaxy Nexus owners are in trouble again. The much awaited Android 4.0.4 ICS update rolled out to Galaxy Nexus and two other devices last week. After this, the users have found the device to lose the signal once it enters the sleep mode.

Usually, when there are no active applications in the background, the phone enters sleep mode. The speed of processor will drop below a particular point and the phone loses the signal. This indicates that the users cannot receive messages or calls until they wake the phone.

This problem can be solved by running some resource heavy application in the background. It also be handled by setting the minimum clock speed of the CPU to 700 MHz instead of 350 MHz. The third way to prevent this issue is to have the sleep mode disabled completely. Remember, none of these options will be kind to the battery life of the handset.

Users who have experienced this issue have mentioned that this happens only with the 4.0.4 build of the Galaxy Nexus. They claim that going to the 4.0.2 ROM resolves the issue.
