Since accepting a forced update on 5/20/14 on my Droid Maxx, my text message notification sound does not work properly. The original Droid sound stopped working after the update. I am able to change to different text notification sounds and each newly selected sound works for a day or so then becomes inaudible again. I can then select a different audible sound and it will work for a day or so and then stop working as well. Multiple restarts of the device has not stabilized the text notification issue either.
The update forced to my device on 5/20/14 was 196.3en obake-maxx-verizonVerizon.enUS. Other phone info is as follows:
I did this trick I learned on Youtube...on the back (below the camera), rub across hard enough (like 3 times?). See if that works. It worked for me. There's a guy on Youtube that shared this amazing trick and it really worked for me! No joke. Razr Maxx sound fix - YouTube
