Making your samsung galaxy s6 faster can be done in a couple of different ways. The first one is to go into the settings and scroll down to about device and click build number and click it 7 times to turn developer options on. Go back and developer options will be opened up so click on it. Then scroll down to the animation scales and turn all of these options off. Basically turning these options off will make sliding from right to left faster, and going back to the home screen faster as well. It basically gets rid of any lag on your galaxy s6 which in turn makes it faster. Another thing you can do to speed up your galaxy s6 is turn off the auto sync option.
