Install an app called "Clean Master" available on the Play Store. It will clear out the thousands of junk files the phone builds up in the onboard memory, slowing it down. i bet your sister never clears out old messages or transfers photos to her memory card rather than keeping them on phone memory.

Doing a "Re-Set" accomplishes all that as well. Just make sure to make a list of the favorite apps you'll need to reinstall and save any pictures or data you don't want to loose.
