Hello Tomas,
I understand wanting to use the zoom feature without the alert notification being on your screen all the time. Since restarting your iPhone SE did not resolve the issue, the next step I would recommend is creating a backup file and then resetting all the settings.
We have 2 ways to backup your iPhone. This link provides the steps for both options:
How to back up your devices using iCloud or iTunes
Once you have backed up your iPhone, you can then reset all the settings.
Reset all settings by tapping Settings > General > Reset > Reset All Settings.
Reset All Settings reloads all the default settings. This is why you want to create a backup file first. This step will forget your Wi-Fi networks, remove any changes to your Alert Styles in Notifications and turns off Locations Services for third-party apps. It also sets Sounds, Brightness, and Wallpaper back to original configurations, removes Battery Usage statistics, and turns off Siri. In addition it turns off Cellular Data, disables Wi-Fi sync, sets Auto-lock back to 1 minute, and removes added International keyboards. All Accessibility options will be turned off as well.
This option does NOT delete anything like pictures, contacts, music or apps. All media and contents will remain after the device resets.
Thank you for using Apple Support Communities.
