I just updated to jellybean last week and one thing I have noticed is that in google now if I search for something like the weather it usually speaks back the result. Today it has stopped speaking all together. I checked the google now settings and it is set to always speak yet I hear nothing except the sound it makes when you finish speaking. it did this a while ago too and since I was already having many problems after the upgrade I did a factory reset and it started speaking again until today. So far the only way I can get it working is to factory reset and i don't feel like doing this every couple of days for just a little feature. Is this a bug with samsung devices with JB?
