Here are symptoms of my Touchpad 3.0.4, I dont want to doctor it rite now since I hop it help to record the problem
1- my music app does not work: I can launch the app, but when I select a song, the I icon show it's playing but no sound and not progress at the bar. I work after restarting my TP, but it happens again
2- I want to restart my touchpad but it took a long time to the touchpad start the restart process. after Choosing restart from device info, my TP hang in there for 5 mins before restarting. This is weird because the touchpad usually restart immediately after the i tap the restart button.
