Android gameport slow when loading new screen

1

I had one windows game I ported really easy for android I implemented bluetooth low energy communication in it,but when I move from one screen to another I wait everything to load several seconds and while that I experience black screen(I am using screenManager in order to move between different screens.)

Is it possible images to slow the game from the windows version do I need to scale them down ?

Or change anything else ?

Please,help

Are you loading new images when you change screens? You probably want to look at how many images you have and how big they are.
Smaller images = faster load times.

Also processing them with the content pipeline will make them load much faster.

Well I have the following ScreenManager :

Is there a way to load the screen once and just reset the main logic of it in order to escape loading it each time ?

My images of the screen that is loading slow are ~300
