After UI 2 and Android 10 update on A50 many of the features are been removed from the Phone..
One of such feature was motion effect while setting wallpapers in A50.
I would Request the developers team of Samsung India, kindly provide Updates to enhance the features of phones/ handsets and not to remove or deteriorate the highlighted and any key features of the set.
This feature uses Accelerometer and Gyroscope to execute so it might have some ill effect on battery. They have removed this feature in ONE UI entirely.
