It's only the first time you need to use the end call button. Otherwise your phone is "sleeping", and the top button wakes from sleep, however if you pull the battery or kill it for a full power-down, you'll need to use the end call button once again to turn it back on.

The stock rom is freaking incredible, best I've ever used. I don't miss 6.5, because 6.5 for me offered nothing more than performance improvement over 6.1, and that isn't a problem on this phone. I didn't use the fancy interface of 6.5 or anything like that, always back to the normal, or spb mobile shell.

The stock speaker is amazing. The clarity and volume which it plays music is outstanding. Really blows me away. It's the type of sound quality you'd expect out of a nice set of powered speakers for your computer to replace your internal poor quality speakers. This, of course, also means speakerphone quality is awesome. And ringer volume.

Also, I have fat fingers. I have found that the diamond keyboard works beautifully with my fingers, and took no getting used to, when using my 6900/touch. Down side, it takes up 60% of the screen.
