Hi there, kinger75002.
I see that you're having an issue with the Maps application after updating your iPhone to iOS 11.2.5. I'm happy to help.
If the screen doesn‘t rotate on your iPhone, iPad, or iPod touch -- Follow the steps in this support article if you've found the issue is happening with other applications as well.
Force an app to close on your iPhone, iPad, or iPod touch -- If the issue only happens with the Maps application, force close the Maps application if it's open, then -- Restart your iPhone, iPad, or iPod touch -- Restart your iPhone. Once it's returned to the Home screen, test the issue.
How to back up your iPhone, iPad, and iPod touch -- If restarting your phone didn't resolve the issue, please be sure to have a fresh backup to keep your personal information safe. In order to back up your Health data, the backup needs to be encrypted. iCloud does this automatically, but iTunes doesn't. If you'd like to use iTunes to back up your phone, refer to this article: About encrypted backups in iTunes
How to check the storage on your iPhone, iPad, and iPod touch -- Go to Settings > General > iPhone Storage. After the list populates, scroll down to "Maps", then tap "Offload App". Once the application has been removed, reinstall it again and test.
Let me know how that goes.
Take care!
