Slider apps (I'm assuming) that first poster is referring to are the ability to add a slide action to the icons on your phone desktop so you can add custom action for the app besides just to open it. They
are usually available with premium versions of launcher apps. So, to the first poster: is your custom launcher still installed and is it set as default? Dumb question perhaps, but have to ask...

Sorry, what I meant was the slider on the lock screen. On it there are several different positions where if you slide to them an app can be opened. On my lock screen the only thing the slider will do is unlock the tablet. I know there is a way to add maybe the camera or contacts to it. The was a way to do it in the previous version of PA but it is missing in 3.0
