Have had my SG2 for 2 months and strangely tonight when a text from my son came through there was a voice announcement telling me I had a message from him. I was a bit shocked as not heard this before and am not aware of altering any settings. My husband has since tried texting me and there was no voice announcement whereas when I asked my son to do it again, I did get the voice but he has no idea why it happened either. (We both have a GS2 but he has been texting me regularly and this has never happened until tonight).
I would love to know what has caused this and obviously then I can choose whether to cancel it.
