Consumed from excessive memory

Normally my device does not consume as much memory and It consumes only between 150 MB or 250 MB the game but in this beta number 6 I will have more of that and causes it to close or break and goes to 340 or 400+ MB and it is not normal that the normal FPS are 30 or 40 But it does not go to that alone it reaches 10 or if it is not that 5 I hope to solve that p
