Question from Glenn_43 : "hyow to connect a sub woofer"

can and how can u connect the vizio sub woofer by itself or to a android phone

Without the model number of the sub itself or the soundbar or HTS it came from we can't know how it was supposed to be connected.
Very unlikely and not useful if you could. If you connected it to a phone would you want to listen to lower bass only?
