Just to test the water resistance of SXZ i drop while playing music half of the phone in a glass of clean water and... the speaker now plays like when you put your finger over the speaker to "fast silence". So: is my first water test, i only drop 3 cm button down (none of the covers USB, SIM, SD or Headphones where underwater). everything works fine even the mic that was also underwater. Any ideas apart sending it back to sony? EDIT: is back on, maybe a security when it detects water?.....
