Hello Dear Android Users. I have a strange problem with my Nexus 7. It mostly crashes while i was playing NFS or FIFA games about five-ten minutes. It also crashes while other apps are running but not that much. I don't know what was wrong but i take photo of the screen maybe somebody had this. When it crashes, sounds are like television which doesn't show things properly.(I don't know how to call this sound.) I bought Nexus about ten days ago. I have an antivirus app and similar security and performance apps. Thank you.
