Both of my Razr Maxx's have lost their sounds. Can't hear incoming calls (no ringing) sounds do not work and when I'm in a call, the speakerphone will not work. Is this a hardware problem. Neither phone has had any abuse whatsoever. It's strange that they both started acting up at the same time. Tried different troubleshooting with no luck. The speaker rub thing did work on one of my phones temporarily. Can I get replacement phones???
