Hi Alyssa_A951,
If you haven't done so yet, it's a good idea to make sure your iPhone is running the latest iOS version, since this can help with overall performance and often fixes unexpected behavior: Update your iPhone or iPad. If an update is available, be sure to create a backup before installing it.
Update your iPhone or iPad wirelessly
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.
If you need more help, reach out to Apple Support directly so they can look into this with you further. They can be contacted here: Get Support or by calling the most applicable phone number from this list: Contact Apple for support and service.
Regards.
