For some reason when I press app icon in the dock the whole dock disappears and at times all of my screens will go blank. Rebooting the phone fixes the problem temporarily. Ive already done a hard reset but for some reason I cant even do the 16mb update. Could it be apex launcher? Seems to me the hard reset didn't fully take it back to factory.
