iPhone has many miscellaneous animations. For example, there is a “maximize window” animation whenever we open an app, and a “minimise window” animation whenever we close an app.
On Android, we can opt to disable animations via Settings → Display → Animations → No animations.
How do we turn off animations on iPhone?
The only way I'm aware of to do this is to use a jailbreak tweak called Springtomize. Apple will not allow you to do this natively since it affects the aesthetic quality of the device. That's just Apple!
Since iOS7 there are a couple of options for reducing animations and other UI effects such as translucency:
Settings > General < Accessibility > Increase Contrast: On/Off and
Settings > General < Accessibility > Reduce Motion: On/Off
I also had the same problem on my iPhone 5s.
When I checked my Reduce Motion setting, it was disabled. Which means there must be motion.
So I powered off my iPhone and powered on it again. After that everything was back to normal.
