How do I uninstall lollipop, the new system update, from my samsung galaxy s5?

[AC Question]

I hate this update and it is impossible to use my phone since the update. How do I uninstall it?

Welcome to the forums. It may be possible to roll it back. You need a ROM file and a PC program called Odin. I would check online to make sure your device can be rolled back. Sometimes, the phone can be bricked if it can't be.
