Troubleshooting Lagging and Stalled Apps:
A. Close All Apps:
These Apps may be open. So, save any information that need be, and then close all apps. Hold you finger down as you swipe up form the bottom-left corner of your screen. Then, close all of these open apps, by sweeping up quickly for all apps.
B. Perform a Force Restart:
