The new update for the android cell phones 4.4.3 is sucking alot how could you uninstall or remove the update?

Question

I already did the factory reset and reset everything and there seems to be no difference. The update is just making my phone so slow and laggy. Before I had the update, my s4 was so fast and there was no lags until the update came and ruined my phone. Please help!!
