We have a Verizon Arris VMS1100 cable tv box for my fios service.

Is there an app or a way that I can remotely control using my Samsung Android phone when I’m not in the house?  My elderly mom sometimes has problems changing the channel or raising the volume using her factory remote control.   If I can do this using my phone for her, then this would save me a lot of time and aggravation with this!

Thanks.
