Slide2Play is a S2 series application. S2P is a stylus-free MP3/WMA player application. It simply lets you browse your music files & play.

Changes:

– added support to HTC Diamond’s shake gesture – ShakeAction: 0 to disable; 1 to go to next song; 2 to go to next shuffle song.
– added support to switch to Album View if your device has a button for changing orientation or a slide out keyboard.
– more “even” shuffling on playback.
– auto-pause the playback when headphone (either Bluetooth or wired) is disconnected (need S2U2 running in the background).
– all graphics support high resolution, i.e. truely VGA.
– simplified the AVRCP trick for Diamond (no need to manually start WMP).
– fixed the system speaker issue when the playback is paused & resumed after a while.
– some graphics changed.
– some minor bugs fixed.
