When looking for a phone many in here (at least the ones active in the Axon 7 forum ) are searching for a flagship device with the best hardware in order to have the best performance and to have their apps start very fast.
As I like my phone fast as well, I have taken a litte extra step to achieve this: I have reduced the animation scale.
When opening an app there always is an animation so the app is not simply put on the screen but more or less fills the screen fluently. But it takes some time.
If you also want to tone that down and make your phone feel snappier, this is the way to go:
That's it! Your phone should feel a little snappier now than it did before!
Hope that helps
