I downloaded the Android 5.0.1 update yesterday, but it still feels really half-baked and a lot of my apps (especially my messaging app) freeze, lag, or otherwise run very slowly. I want to know if there is a way I can revert to Android 4.4.4, what I had before the update. I've found plenty of guides on how to revert on stock Android (Nexus) devices, but nothing for my specific phone. All I've found is some custom ROMs, but I was hoping to go back to exactly what I had or very close to it.
Since I would most likely need to root my device to do this, maybe I'd be better off with a custom version of Android? Or, should I just wait for updates?
