I have 4 Blue ones. 2 are now activated. Crazy fast restore from Google Drive and CM Backup.
1. I am with you about the Sprint Voice Mail. Had to set up my voice greeting once again. I am not used to the Google phone app.
2. Boom sound is pretty good. Not as loud as the M8 playing the same song on Spotify, but sound is clearer.
3. Ultrasonic headphones definitely noise cancel well, and I think they sound better than the HK headphones on the M8 Harman Kardon edition.
4. Phone is slippery.
5. Sprint LTE download speed at my house is 35 MB/sec vs 17 on my M8. Nice radio. A little slower than my iPhone 7 Plus download speed on Verizon at 50 MB/sec.
6. I miss the IR remote control on my M8.
7. FM radio with Next is a big NO GO.
8. Initial camera thoughts are that it is as good as the iPhone 7 Plus, but the portrait mode on 7 Plus still is better.
