Hi ShystaZeb,
It sounds like you had a question about rotate working for your iPhone, and I want to help.
Does the screen rotate the controls if you are using the Camera app? That's a good indicator that rotation is working.
Check out these steps here:
If the screen doesn't rotate on your iPhone, iPad, or iPod touch - Apple Support
If you've taken those steps and restarted your iPhone and the issue persists, I recommend contacting Apple Support or visiting the nearest Apple Store or Apple Authorized Service Provider to assess the situation further:
Contact - Official Apple Support
Apple - Find Locations - Location Selector
Good luck!
Thanks for using the Apple Support Communities.
