Default [Q] Microphone problems

Hi there, proud new owner here, a tiny bit dissapointed with washed out colours /Im coming from an unbeatable amoled screen of Samsung Galaxy Tab 7.7/ and not being able to sync my Jawbone Up /did anyone manage to find a solution for that?/, but my main problem is facebook messenger crashing when attempting a voice messege. Im C6833 14.2.A.0.290. I've noticed that initiating voice recording in facebook messenger disables the microphone until I restart the device? wtheck? Does that happen to any of you? THANKS!
