When I receive a call and I miss it, the notification will pop up on my lock screen then disappear after about 3 seconds. If I unlock my phone, I don't have any notification whatsoever that I missed a call. The only way to tell is to open the phone icon and view missed calls. This is not normal, how do I fix this? Messages and other notifications work like they are supposed to.

Correct! Safe mode disables third-party apps from running in the background. I recommend deleting the most recent apps you have downloaded and keep testing until you are able to see your notifications pop up.
Before you start troubling your phone, do this; remove CCleaner if you have it on your phone: Cache cleaner, Ram Cleaner, Booster by Piriform or similar app, and try again. It blocks notification for phone missed calls and some other notifications.
