Already updated to Lollipop. So far it's. One thing I noticed is that the battery is draining fast just like my experience on the Kitkat update because of the Android system that's been consuming the battery.. And on my Nova launcher, stock apps (Calendar, Calculator, and the likes) their normal logo is not originally shown, since I only use the default logo theme. And there's some data waste in the storage that really uses up my storage. So I factory reset it and walah! It was better than ever annd I boy I will be stressed in restoring it xD. But the update is very beautiful. It's so worth it. So to those who plan to update, do it. Just back-up your data on your phone and factory reset it after the update. Resetting it would remove most of the issues in my view.
