I have just recently bought the Moto g 3 the one with 8gb memory and 1 gb of ram. So there are to ways in closing apps 1 is when the little X appears on the right corner and there's the other way where I can swipe left or right to close apps well I notice there are times when swiping the apps to close it doesn't close smoothly I get some lag or stutter then there are times is closes quick ?
