Verizon - My phone gets hot when it's on the charger and when my grand daughter watches movies is?

This happens alot actually truth be told even if your phone is new, having it plugged in , you should just let it charge up, its not like a laptop computer, that might not overheat at first....but eventually youll notice slower performance.

My tip to you is, let it fully charge then take it off the charger IMMEDIATELY when its done charging youll retain optimal battery life this way.
