"Android.process.media has stopped unexpectedly" error when I boot my Galaxy Nexus Every time I boot my phone it gives the error message android.process.media has stopped unexpectedly. Why?

I am using 4.0.2 on my Galaxy Nexus.
The process error you are getting is android.process.media
The clue is in the media part. 


You should go to Settings > Applications > Manage Applications > Then make sure you look under the ALL tab. It is MEDIA what you are looking for. 
Clear the data and cache for this one. Then Force-stop it and restart your device. 


When it restarts, it should restart normal and the media will start again automatically without the issue.
