Hello shonna225,
Let's use the steps below to make sure that your iPhone is all up to date:
1. Back up your device using iCloud or your computer.
2. Plug your device into power and connect to the internet with Wi-Fi.
3. Go to Settings > General, then tap Software Update.
4. If you see more than one software update option available, choose the one that you want to install.

5. Tap Install Now. If you see Download and Install instead, tap it to download the update, enter your passcode, then tap Install Now. If you don't know your passcode, learn what to do.
You can also find those steps in this resource: Update your iPhone or iPad - Apple Support
If your iPhone is all up to date, let's restart using the steps from this resource: Restart your iPhone - Apple Support
Updating and restarting can sometimes help address odd behaviors.
Should that still persist you'll want to reach out to Apple Support so they can look into this further: Contact - Official Apple Support
Take care.
