Moto E on Lollipop has KitKat's boot animation I have a Moto E 1st Gen. When I updated to Lollipop, my boot animation updated too, but a few months later I did a hard reset to my Moto E. All was great, but yesterday I noticed that my boot animation is back to what it was on KitKat.

Is there a problem, and what can I do?
My Moto X did this same thing for almost a month after Lollipop was released. Eventually, Motorola Boot Services updated through Google Play and the animation updated. It also introduced a few bugs Motorola has yet to fix, but give it time, and you will receive that update again relatively soon.
