Did you clear all your active background tabs and then restart the phone. A lot of times, a simple restart fixes any glitches or hiccups.

Why don't hit "close all" reboot your phone and see if the behavior continues?

Try wiping the cache partition. 

1. Power off your Galaxy phone.  Hold Power and vol up buttons until Samsung Logo appears

2. Let go of both buttons when you see the Samsung Logo appear on screen. There will be a delay while it enters recovery mode.

3. Use the volume buttons to navigate through recovery menu options and highlight “Wipe Cache Partition.” Press power button to select this option . Confirm by navigating to the yes response and tapping the power button to select.

5 .When wiping cache partition is complete, "reboot system now" should be highlighted; press power key to select it. The phone will reboot as normal.
