i have an accelerometer object in my game it works but when i try 2 remove it

display.remove(acce)

acce=nil

the accelerometer does not work…

i ned to remove my object with the use of accelerometer because when im not remove it or i use group:insert(acce)

my game is becoming to lag…

thats why i ned to use 

display.remove(acce)

acce=nil

to prevent lag.

 

but the problem is after removing my object and i go to other scene or i restart my game the accelerometer does not work…
