I went from the 4 to a 5s and it is great. My problem is that Siri doesn't work half of the time. I can be in my car with windows up and radio off trying to dictate a simple 5 or 6 word sentence in a text and all I get is the blue circle showing me Siri is trying to create the text. The issue is the blue circle will keep going and no text pops up. If I open Siri and try to open up an internet search I get the I am sorry I can't take any requests right now. Please try again later. What is going on? Turning Siri off and on again doesn't help. Reboot helps sometimes. Any help or suggestions would be appreciated.
