My phone went dead in class i get back home put it on the charger and it says charging, i go downstairs and eat i comeback up stairs and my phone is not turning on or charging i did not drop it today or it did not come in contact with water. Please help!!

I’m going to lean towards a battery replacement, probably due to a poor quality aftermarket charger. It’s not impossible. Just takes a little doing Parts Galaxy S7 Battery Guide Samsung Galaxy S7 Battery Replacement

Try holding volume down + power and home button for 10 seconds and try turning it on again.
