My app lags for a second on Snapdragon 435 devices

Hello I want to make my smooth as smooth as possible currently I have 3 pages in my app 1. Home, 2. Settings 3. Main
Home and Settings page are in one screen
Main page is on another screen.

I have a list view on home page so whenever a user select list item from snapdragon 435 device or below that processor then my app takes a 1-2 seconds pause before opening the another screen (main screen) it takes noticeable amount of time which I want to minimize or completely remove this lag. So please tell me what can be done regarding this.
