I had this happen twice today. I have become pretty reliant on BT and today it dropped two phone calls "in call". I noticed during one of the drops that some automatic app updating was occuring during my call. I really like that I can surf the web while in call but I can't forsake or forgive if my lte is going to drop bluetooth in call while some random app thinks it needs to download an update. Anyone else notice a similar issue. I'm going to keep track of it for a while to see if it occurs again and if so what is going on at the time.
