I tried to use the dictation voice-to-text feature (press picture of mic when composing email), but the phone allowed only about 2 seconds of silence before terminating the dictation. Unfortunately, I cannot say anything worthy of dictation without any 2-second pauses and I get disappointed when I look back at the phone and see that it has ignored everything I said after the first inhale. How can I put the phone firmly into dictation mode so it will stay there until I am done talking?
