Beginner Level 2
I own a Galaxy M31s since 4 to 5 months. But since the last software update, I experience some lags with my phone's display. 
When I open or close or browse through the task manager, I feel some lag like that of an FPS rate drop. I am not a professional in this matter so maybe FPS would be wrong. But it could be a refresh rate problem also. So if anyone has solutions to this kindly reply. 

Thanks a lot! Have a great day.

As we all know exynos processor are not that good for gaming. Except 2100 cause I don't know about that chipset yet. So while gaming i suggest you to clear all the background application. It might help you.
