How do I uninstall a system update on my s7 edge

[AC Question]

I don't like the new update. I can't find my flashlight on my phone now. I just to could pull my screen down and it would have all of my options to choose from.

Welcome to Android Central! You can't uninstall updates. You might be able to flash the previous firmware using Odin: http://forums.androidcentral.com/am...w-flash-stock-rom-via-odin-new-interface.html

Is the flashlight issue the only reason, or are there a lot more?

Yes indeed, you can downgrade or upgrade your OS with Odin 3 , Kies 3 or smart switch.
But be aware , installing a custom OS will void warranty and permanently lock your acces to KNOX containers.
