As far as the seeing the songs in the album together you should be able to go to Folders>Library>Albums and see them by the Album and not the artist. Same with Stock player. As the charging goes I didn't see any problem with my Epic. I wonder if it is an issue with with the DX and something.
It be great to have a notifications on the unlock screen for things like emails, texts and missed calls. Also make it so you can click on them and go straight to the message. I think that is will look better with a few icons than having the bar with the lock screen.
