Hello all. I am a new user of the Huawei Ascend Y (I think it's what I have..H866C) from straight talk. Anyway, I seriously need to figure out how to disable the alarming sound that comes from my phone when one of those CMAS alerts comes through. Even the test messages have that alarming, loud sound like the test of the emergency broadcast system. I always have my phone on silent/vibrate and it still makes the sound which is very disruptive at my workplace. Help
