Why is my internet not connecting despite strong 4G signal?

AC Question

Device: Samsung S5

Today I've noticed that all my widgets were not displaying any information and my google search bar would not establish an internet connection. My phone had a strong 4G signal strength. I am able to use the phone as well as refresh apps like Facebook and Twitter. As well my texts conversations are not displaying in chronological order. Instead my messages flash once I send and then disappear or appear at the very top of my conversation while my received messages appear one after another at the bottom of the conversation.
