Android phone animations have stop working As title suggests it is a very strange problem I am facing. My phone has stopped showing usual animations instead it just gives jerk effects, or freezes,

1) for example the traditional google play store animations when you click on any apps,

2) another example is of loading bars, which just freezes and doesn't perform its regular animation.

I have attached small video files to make this more clear with both aforementioned examples. 

Another examples to support this are in my android applications which I develop, none of the progress bars or animations work. All loaders just freezes like mentioned in the videos, I use some reveal animation libraries and fancy loaders libraries as well and their animations also don't work.

I checked to see the settings whether I messed up any settings or not but could not find it. Can anyone help me make solution out of this. 
My model is samsung S5 neo running Android 7.0. 

Thank you in advance.
The animation scale options are turned off in developer options and by turning it on it works as expected..
