Re: Text message "FROM" issue on 8.4 Nav
Same issue here using the HTC One on AT&T with the 4.4.2 kit kat update.
What I have found is if you delete and repair, you will receive messages for the first engine cycle or so, then you will stop being notified of texts again after that.
The only thing that seems to work is to completely clear your text history and limit the number of messages to 10 for any conversation. This seems to get the texting notification to work longer. I think it's a memory issue on UConnect's part. Perhaps it can be updated in future software versions.
Remember, in order to create free form texts via voice, you have to subscribe to Uconnect for $20 a month and this only works on certain phones. I do not think the S4 will work with free form - the HTC does and that's why I got the phone. Just wish I could get the receiving feature to be more consistent!
