I am creating a 2d game to android
When i am sending versions of the game to my phone
I open the gane and i am playing a while
And suddenly the game slowly starts to slow down even though the fps is on 50( i have a text with code that show this to me)
What is the problem?

If the game feels laggy while the FPS is on 50 then you may have frame spikes, to make sure you need to record 1% lows and 0.1% of the FPS, if those are dropping to 30 or below then that would explain why the game feels slow.
